用于返回计算机上 .NET Framework 版本的 PowerShell 脚本?

发布于 2024-09-14 02:21:17 字数 126 浏览 2 评论 0 原文

返回计算机上 .NET Framework 版本的 PowerShell 脚本是什么?

我的第一个猜测是涉及 WMI 的东西。还有更好的吗?

它应该是一行,为每次 .NET 安装[在每一行]仅返回最新版本。

What would a PowerShell script be to return versions of the .NET Framework on a machine?

My first guess is something involving WMI. Is there something better?

It should be a one-liner to return only the latest version for each installation of .NET [on each line].

如果您要使用注册表,则必须递归才能获取 4.x 框架的完整版本。早期的答案都返回我系统上 .NET 3.0 的根编号(其中嵌套在 3.0 下的 WCF 和 WPF 编号更高 - 我无法解释这一点),并且无法返回 4.0 的任何内容。 编辑:

对于 .Net 4.5 及更高版本,这再次略有变化,因此现在有一个很好的 MSDN这里的文章解释了如何将 Release 值转换为 .Net 版本号,这简直就是一场灾难:-(

这对我来说看起来很正确(请注意,它为 WCF 输出单独的版本号& 3.0 上的 WPF 我不知道那是什么)。它还在 4.0 上输出 ClientFull(如果您安装了它们)

Get-ChildItem 'HKLM:\SOFTWARE\Microsoft\NET Framework Setup\NDP' -recurse |
Get-ItemProperty -name Version,Release -EA 0 |
Where { $_.PSChildName -match '^(?!S)\p{L}'} |
Select PSChildName, Version, Release

: MSDN 文章中,您可以构建一个查找表并返回 4.5 之后版本的营销产品版本号:

$Lookup = @{
    378389 = [version]'4.5'
    378675 = [version]'4.5.1'
    378758 = [version]'4.5.1'
    379893 = [version]'4.5.2'
    393295 = [version]'4.6'
    393297 = [version]'4.6'
    394254 = [version]'4.6.1'
    394271 = [version]'4.6.1'
    394802 = [version]'4.6.2'
    394806 = [version]'4.6.2'
    460798 = [version]'4.7'
    460805 = [version]'4.7'
    461308 = [version]'4.7.1'
    461310 = [version]'4.7.1'
    461808 = [version]'4.7.2'
    461814 = [version]'4.7.2'
    528040 = [version]'4.8'
    528049 = [version]'4.8'
}

# For One True framework (latest .NET 4x), change the Where-Object match 
# to PSChildName -eq "Full":
Get-ChildItem 'HKLM:\SOFTWARE\Microsoft\NET Framework Setup\NDP' -Recurse |
  Get-ItemProperty -name Version, Release -EA 0 |
  Where-Object { $_.PSChildName -match '^(?!S)\p{L}'} |
  Select-Object @{name = ".NET Framework"; expression = {$_.PSChildName}},

事实上,由于我必须不断更新此答案,因此这里有一个脚本用于从该网页的 Markdown 源。这可能会在某个时候中断,所以我保留上面的当前副本。

# Get the text from github
$url = "https://raw.githubusercontent.com/dotnet/docs/master/docs/framework/migration-guide/how-to-determine-which-versions-are-installed.md"
$md = Invoke-WebRequest $url -UseBasicParsing
$OFS = "`n"
# Replace the weird text in the tables, and the padding
# Then trim the | off the front and end of lines
$map = $md -split "`n" -replace " installed [^|]+" -replace "\s+\|" -replace "\|$" |
    # Then we can build the table by looking for unique lines that start with ".NET Framework"
    Select-String "^.NET" | Select-Object -Unique |
    # And flip it so it's key = value
    # And convert ".NET FRAMEWORK 4.5.2" to  [version]4.5.2
    ForEach-Object { 
        [version]$v, [int]$k = $_ -replace "\.NET Framework " -split "\|"
        "    $k = [version]'$v'"
    }

# And output the whole script
@"
`$Lookup = @{
$map
}

# For extra effect we could get the Windows 10 OS version and build release id:
try {
    `$WinRelease, `$WinVer = Get-ItemPropertyValue "HKLM:\SOFTWARE\Microsoft\Windows NT\CurrentVersion" ReleaseId, CurrentMajorVersionNumber, CurrentMinorVersionNumber, CurrentBuildNumber, UBR
    `$WindowsVersion = "`$(`$WinVer -join '.') (`$WinRelease)"
} catch {
    `$WindowsVersion = [System.Environment]::OSVersion.Version
}

Get-ChildItem 'HKLM:\SOFTWARE\Microsoft\NET Framework Setup\NDP' -Recurse |
    Get-ItemProperty -name Version, Release -EA 0 |
    # For The One True framework (latest .NET 4x), change match to PSChildName -eq "Full":
    Where-Object { `$_.PSChildName -match '^(?!S)\p{L}'} |
    Select-Object @{name = ".NET Framework"; expression = {`$_.PSChildName}}, 
                @{name = "Product"; expression = {`$Lookup[`$_.Release]}}, 
                Version, Release,
    # Some OPTIONAL extra output: PSComputerName and WindowsVersion
    # The Computer name, so output from local machines will match remote machines:
    @{ name = "PSComputerName"; expression = {`$Env:Computername}},
    # The Windows Version (works on Windows 10, at least):
    @{ name = "WindowsVersion"; expression = { `$WindowsVersion }}
"@

If you're going to use the registry you have to recurse in order to get the full version for the 4.x Framework. The earlier answers both return the root number on my system for .NET 3.0 (where the WCF and WPF numbers, which are nested under 3.0, are higher -- I can't explain that), and fail to return anything for 4.0 ...

EDIT: For .Net 4.5 and up, this changed slightly again, so there's now a nice MSDN article here explaining how to convert the Release value to a .Net version number, it's a total train wreck :-(

This looks right to me (note that it outputs separate version numbers for WCF & WPF on 3.0. I don't know what that's about). It also outputs both Client and Full on 4.0 (if you have them both installed):

Get-ChildItem 'HKLM:\SOFTWARE\Microsoft\NET Framework Setup\NDP' -recurse |
Get-ItemProperty -name Version,Release -EA 0 |
Where { $_.PSChildName -match '^(?!S)\p{L}'} |
Select PSChildName, Version, Release

Based on the MSDN article, you could build a lookup table and return the marketing product version number for releases after 4.5:

$Lookup = @{
    378389 = [version]'4.5'
    378675 = [version]'4.5.1'
    378758 = [version]'4.5.1'
    379893 = [version]'4.5.2'
    393295 = [version]'4.6'
    393297 = [version]'4.6'
    394254 = [version]'4.6.1'
    394271 = [version]'4.6.1'
    394802 = [version]'4.6.2'
    394806 = [version]'4.6.2'
    460798 = [version]'4.7'
    460805 = [version]'4.7'
    461308 = [version]'4.7.1'
    461310 = [version]'4.7.1'
    461808 = [version]'4.7.2'
    461814 = [version]'4.7.2'
    528040 = [version]'4.8'
    528049 = [version]'4.8'
}

# For One True framework (latest .NET 4x), change the Where-Object match 
# to PSChildName -eq "Full":
Get-ChildItem 'HKLM:\SOFTWARE\Microsoft\NET Framework Setup\NDP' -Recurse |
  Get-ItemProperty -name Version, Release -EA 0 |
  Where-Object { $_.PSChildName -match '^(?!S)\p{L}'} |
  Select-Object @{name = ".NET Framework"; expression = {$_.PSChildName}}, 
@{name = "Product"; expression = {$Lookup[$_.Release]}}, 
Version, Release

In fact, since I keep having to update this answer, here's a script to generate the script above (with a little extra) from the markdown source for that web page. This will probably break at some point, so I'm keeping the current copy above.

# Get the text from github

# Replace the weird text in the tables, and the padding
# Then trim the | off the front and end of lines
$map = $md -split "`n" -replace " installed [^|]+" -replace "\s+\|" -replace "\|$" |
    # Then we can build the table by looking for unique lines that start with ".NET Framework"
    Select-String "^.NET" | Select-Object -Unique |
    # And flip it so it's key = value
    # And convert ".NET FRAMEWORK 4.5.2" to  [version]4.5.2
    ForEach-Object { 
        [version]$v, [int]$k = $_ -replace "\.NET Framework " -split "\|"
        "    $k = [version]'$v'"
    }

    `$WindowsVersion = "`$(`$WinVer -join '.') (`$WinRelease)"
} catch {
    `$WindowsVersion = [System.Environment]::OSVersion.Version

为脚本添加了 v4.8 支持:

Get-ChildItem 'HKLM:\SOFTWARE\Microsoft\NET Framework Setup\NDP' -recurse |
Get-ItemProperty -name Version,Release -EA 0 |
Where { $_.PSChildName -match '^(?![SW])\p{L}'} |
Select PSChildName, Version, Release, @{
  name="Product"
  expression={
      switch -regex ($_.Release) {
        "378389" { [Version]"4.5" }
        "378675|378758" { [Version]"4.5.1" }
        "379893" { [Version]"4.5.2" }
        "393295|393297" { [Version]"4.6" }
        "394254|394271" { [Version]"4.6.1" }

        {$_ -gt 528049} { [Version]"Undocumented version (> 4.8), please update script" }
      }
    }
}

Added v4.8 support to the script:

Get-ChildItem 'HKLM:\SOFTWARE\Microsoft\NET Framework Setup\NDP' -recurse |
Get-ItemProperty -name Version,Release -EA 0 |
Where { $_.PSChildName -match '^(?![SW])\p{L}'} |

[environment]::Version

为您提供 Version 的实例对于当前 PSH 副本正在使用的 CLR(如此处记录< /a>)。

[environment]::Version

Gives you an instance of Version for the CLR the current copy of PSH is using (as documented here).

gci 'HKLM:\SOFTWARE\Microsoft\NET Framework Setup\NDP' |
sort pschildname -des                                  |
select -fi 1 -exp pschildname

如果已安装,此答案不会返回 4.5。下面来自 @Jaykul 的答案和使用递归确实如此。

gci 'HKLM:\SOFTWARE\Microsoft\NET Framework Setup\NDP' |
sort pschildname -des                                  |
select -fi 1 -exp pschildname

This answer doesn't return 4.5 if that is installed. The answer below from @Jaykul and using recurse does.

梦里人 2024-09-21 02:21:17

正确的语法:

[System.Runtime.InteropServices.RuntimeEnvironment]::GetSystemVersion()
#or
$PSVersionTable.CLRVersion

GetSystemVersion函数返回一个像这样的字符串:

v2.0.50727        #PowerShell v2.0 in Win 7 SP1

或者像这样

v4.0.30319        #PowerShell v3.0 (Windows Management Framework 3.0) in Win 7 SP1

$PSVersionTable< /a> 是只读对象。 CLRVsion 属性是一个结构化版本号,如下所示:

Major  Minor  Build  Revision
-----  -----  -----  --------
4      0      30319  18444   

Correct syntax:

[System.Runtime.InteropServices.RuntimeEnvironment]::GetSystemVersion()
#or
$PSVersionTable.CLRVersion

The GetSystemVersion function returns a string like this:

v2.0.50727        #PowerShell v2.0 in Win 7 SP1

or like this

v4.0.30319        #PowerShell v3.0 (Windows Management Framework 3.0) in Win 7 SP1

$PSVersionTable is a read-only object. The CLRVersion property is a structured version number like this:

Major  Minor  Build  Revision
-----  -----  -----  --------
4      0      30319  18444

我通过 osx 的 powershell 中的选项卡补全找到了这一点:

[System.Runtime.InteropServices.RuntimeInformation]::get_FrameworkDescription()
.NET Core 4.6.25009.03

I found this through tab completion in powershell for osx:

[System.Runtime.InteropServices.RuntimeInformation]::get_FrameworkDescription()
.NET Core 4.6.25009.03

不错的解决方案

尝试使用可下载的 DotNetVersionLister 模块 (基于注册表信息和一些版本到营销版本的查找表)。

可以像这样使用:

PS> Get-DotNetVersion -LocalHost -nosummary


ComputerName : localhost
>=4.x        : 4.5.2
v4\Client    : Installed
v4\Full      : Installed
v3.5         : Installed
v3.0         : Installed
v2.0.50727   : Installed
v1.1.4322    : Not installed (no key)
Ping         : True
Error        :

或者像这样,如果您只想测试某些 .NET 框架 >= 4.*

PS> (Get-DotNetVersion -LocalHost -nosummary).">=4.x"
4.5.2

但它不会工作(安装/导入),例如 >PS v2.0Win 7Win Server 2010 标准)由于不兼容...

下面的“遗留”功能的动机

(您可以跳过阅读并使用下面的代码)

我们必须在某些计算机上使用PS 2.0,并且无法安装/导入上述DotNetVersionLister
在其他计算机上,我们想要更新(从PS 2.0)到PS 5.1(这又需要.NET Framework >= 4.5)两个公司自定义 Install-DotnetLatestCompanyInstall-PSLatestCompany 的帮助。
为了很好地指导管理员完成安装/更新过程,我们必须确定所有计算机上这些功能的 .NET 版本以及现有的 PS 版本。
因此,我们还使用以下函数在所有环境中更安全地确定它们...

旧 PS 环境的函数(例如 PS v2.0

因此以下代码和下面(提取的)使用示例非常有用此处(基于此处的其他答案):

Nice solution

Try using the downloadable DotNetVersionLister module (based on registry infos and some version-to-marketing-version lookup table).

Which would be used like this:

PS> Get-DotNetVersion -LocalHost -nosummary


ComputerName : localhost
>=4.x        : 4.5.2
v4\Client    : Installed
v4\Full      : Installed
v3.5         : Installed
v3.0         : Installed
v2.0.50727   : Installed
v1.1.4322    : Not installed (no key)
Ping         : True
Error        :

Or like this if you just want to test it for some .NET framework >= 4.*:

PS> (Get-DotNetVersion -LocalHost -nosummary).">=4.x"
4.5.2

But it will not work (install/import) e.g. with PS v2.0 (Win 7, Win Server 2010 standard) due to incompatibility...

Motivation for "legacy" functions below

(You could skip reading this and use code below)

We had to work with PS 2.0 on some machines and could not install/import the above DotNetVersionLister.
On other machines we wanted to update (from PS 2.0) to PS 5.1 (which in turn needs .NET Framework >= 4.5) with the help of two company-custom Install-DotnetLatestCompany and Install-PSLatestCompany.
To guide admins nicely through the install/update process we would have to determine the .NET version in these functions on all machines and PS versions existing.
Thus we used also the below functions to determine them more safely in all environments...

Functions for legacy PS environments (e.g. PS v2.0)

So the following code and below (extracted) usage examples are useful here (based on other answers here):

        Get-DotNetVersion 
          from DotNetVersionLister module (https://github.com/EliteLoser/DotNetVersionLister), 
          but it is not usable/importable in PowerShell 2.0 
        Get-DotNetVersionByReg
          reg(istry) based: (available herin as well) but it may return some wrong version or may not work reliably for versions > 4.5 
          (works in PSv2.0)
      Get-DotNetVersionByFs (this):  
        f(ile) s(ystem) based: determines the latest installed .NET version based on $Env:windir\Microsoft.NET\Framework content
        this is unreliable, e.g. if 4.0* is already installed some 4.5 update will overwrite content there without
        renaming the folder
        (works in PSv2.0)

请参阅页面用于查找远程工作站上安装的 .NET 版本的脚本

那里的脚本可能有助于查找网络上多台计算机的 .NET 版本。

Refer to the page Script for finding which .NET versions are installed on remote workstations.

The script there might be useful to find the .NET version for multiple machines on a network.

以下是我对这个问题的看法 msft 文档

$gpParams = @{
    Path        = 'HKLM:\SOFTWARE\Microsoft\NET Framework Setup\NDP\v4\Full'
    ErrorAction = 'SilentlyContinue'
}
$release = Get-ItemProperty @gpParams | Select-Object -ExpandProperty Release

".NET Framework$(
    switch ($release) {
        ({ $_ -ge 528040 }) { ' 4.8'; break }
        ({ $_ -ge 461808 }) { ' 4.7.2'; break }
        ({ $_ -ge 461308 }) { ' 4.7.1'; break }
        ({ $_ -ge 460798 }) { ' 4.7'; break }
        ({ $_ -ge 394802 }) { ' 4.6.2'; break }
        ({ $_ -ge 394254 }) { ' 4.6.1'; break }
        ({ $_ -ge 393295 }) { ' 4.6'; break }
        ({ $_ -ge 379893 }) { ' 4.5.2'; break }
        ({ $_ -ge 378675 }) { ' 4.5.1'; break }
        ({ $_ -ge 378389 }) { ' 4.5'; break }
        default { ': 4.5+ not installed.' }
    }
)"

此示例适用于所有 PowerShell 版本,并且将永久有效,因为 4.8 是最后一个 .NET Framework 版本。

Here's my take on this question following the msft documentation:

$gpParams = @{
    Path        = 'HKLM:\SOFTWARE\Microsoft\NET Framework Setup\NDP\v4\Full'
    ErrorAction = 'SilentlyContinue'
}
$release = Get-ItemProperty @gpParams | Select-Object -ExpandProperty Release

".NET Framework$(
    switch ($release) {
        ({ $_ -ge 528040 }) { ' 4.8'; break }
        ({ $_ -ge 461808 }) { ' 4.7.2'; break }
        ({ $_ -ge 461308 }) { ' 4.7.1'; break }
        ({ $_ -ge 460798 }) { ' 4.7'; break }
        ({ $_ -ge 394802 }) { ' 4.6.2'; break }
        ({ $_ -ge 394254 }) { ' 4.6.1'; break }
        ({ $_ -ge 393295 }) { ' 4.6'; break }
        ({ $_ -ge 379893 }) { ' 4.5.2'; break }
        ({ $_ -ge 378675 }) { ' 4.5.1'; break }
        ({ $_ -ge 378389 }) { ' 4.5'; break }
        default { ': 4.5+ not installed.' }
    }
)"

This example works with all PowerShell versions and will work in perpetuity as 4.8 is the last .NET Framework version.

这纯粹是因为当它应该广泛可用时我不得不花时间制作/编辑它,所以我将它提供给其他人。

以下脚本将向 TEMP 输出几个 CSV 文件,其中包含所选(代码中)OU 中每台计算机的版本和漏洞状态。您将能够远程“安全审核”计算机的 OU。

连接测试线需要Powershell 7.0
获取AD模块需要RSAT
Visual Studio Code 需要获取 powershell 7.0(在 win7 上)

当您阅读本文时,文件中的版本列表可能已经过时。使用此网站 https://learn.microsoft .com/en-us/dotnet/framework/migration-guide/versions-and-dependencies 添加较新的 dotnet 条目。它只是“DotNet4Builds”中的一堆关键值。

如果在 CompromishedCheck.csv 中,一台机器显示为 =0,则表明它的安全性已手动关闭,您应该提出是否是供应商干的,或者是可疑员工干的。

我希望这可以帮助那些正在寻找其业务的人。

This is purely because I had to spend time making/editing this when it should be widely available, so I'm providing it to everyone else.

The below script will Output a couple of CSV files to TEMP with the versions and vulnerability status of each machine in a selected (in the code) OU. You'll be able to remotely "security audit" an OU of machines.

Powershell 7.0 needed for the connection test line
RSAT needed to get the AD module
Visual Studio Code needed to get powershell 7.0 (on win7)

By the time you read this, the version list will probably be out of date within the file. Use this website https://learn.microsoft.com/en-us/dotnet/framework/migration-guide/versions-and-dependencies to add newer dotnet entries. It's just a bunch of key values in "DotNet4Builds"

If within CompromisedCheck.csv a machine shows as =0, it's had it's security turned off manually, and you should raise whether the supplier did it, or a suspect employee.

I hope this helps someone searching for it for their business.

不漂亮。 绝对不太好:

ls $Env:windir\Microsoft.NET\Framework | ? { $_.PSIsContainer } | select -exp Name -l 1

这可能有效,也可能无效。但就最新版本而言,这应该是相当可靠的,因为旧版本(1.0、1.1)基本上是空文件夹,但新版本没有——这些文件夹只有在安装了适当的框架后才会出现。

不过,我怀疑一定有更好的方法。

Not pretty. Definitely not pretty:

ls $Env:windir\Microsoft.NET\Framework | ? { $_.PSIsContainer } | select -exp Name -l 1

This may or may not work. But as far as the latest version is concerned this should be pretty reliable, as there are essentially empty folders for old versions (1.0, 1.1) but not newer ones – those only appear once the appropriate framework is installed.

Still, I suspect there must be a better way.

目前,从 v8x 开始,dotnet.exe --info 返回当前 shell 的版本。

Well currently as of v8x dotnet.exe --info returns a version for the current shell.

我会在 PowerShell 中尝试这个:
为我工作!

(Get-ItemProperty "HKLM:Software\Microsoft\NET Framework Setup\NDP\v4\Full").Version

I would try this one in PowerShell:

(Get-ItemProperty "HKLM:Software\Microsoft\NET Framework Setup\NDP\v4\Full").Version

总体思路如下:

获取 .NET Framework 目录中的子项,这些子项是名称匹配的容器
图案v号点号。按名称降序对它们进行排序,取第一个对象,
并返回其 name 属性。

这是脚本:

(Get-ChildItem -Path $Env:windir\Microsoft.NET\Framework | Where-Object {$_.PSIsContainer -eq $true } | Where-Object {$_.Name -match 'v\d\.\d'} | Sort-Object -Property Name -Descending | Select-Object -First 1).Name

Here's the general idea:

Get child items in the .NET Framework directory that are containers whose names match
the pattern v number dot number. Sort them by descending name, take the first object,
and return its name property.

Here's the script:

(Get-ChildItem -Path $Env:windir\Microsoft.NET\Framework | Where-Object {$_.PSIsContainer -eq $true } | Where-Object {$_.Name -match 'v\d\.\d'} | Sort-Object -Property Name -Descending | Select-Object -First 1).Name

如果您的计算机上已安装 Visual Studio,则打开 Visual Studio 开发人员命令提示符并键入以下命令:
clrver

它将列出该计算机上所有已安装的 .NET Framework 版本。

If you have installed Visual Studio on your machine then open the Visual Studio Developer Command Prompt and type the following command:
clrver

It will list all the installed versions of .NET Framework on that machine.

这是上一篇文章的衍生版本,但在我的测试中它获取了最新版本的 .net Framework 4。

get-itemproperty -name version,release "hklm:\SOFTWARE\Microsoft\NET Framework Setup\NDP\v4\FULL"

这将允许您调用命令到远程计算机:

invoke-command -computername server01 -scriptblock {get-itemproperty -name version,release "hklm:\SOFTWARE\Microsoft\NET Framework Setup\NDP\v4\FULL" | select pscomputername,version,release} 

这使用 ADModule 和命名约定前缀设置了这种可能性:

get-adcomputer -Filter 'name -like "*prefix*"' | % {invoke-command -computername $_.name -scriptblock {get-itemproperty -name version,release "hklm:\SOFTWARE\Microsoft\NET Framework Setup\NDP\v4\FULL" | select pscomputername,version,release}} | ft

This is a derivite of previous post, but this gets the latest version of the .net framework 4 in my tests.

get-itemproperty -name version,release "hklm:\SOFTWARE\Microsoft\NET Framework Setup\NDP\v4\FULL"

Which will allow you to invoke-command to remote machine:

invoke-command -computername server01 -scriptblock {get-itemproperty -name version,release "hklm:\SOFTWARE\Microsoft\NET Framework Setup\NDP\v4\FULL" | select pscomputername,version,release} 

Which sets up this possibility with ADModule and naming convention prefix:
