如何以编程方式确定已安装的 IIS 版本

发布于 2024-07-10 20:18:01 字数 237 浏览 9 评论 0原文

以编程方式确定当前安装的 Microsoft Internet 信息服务 (IIS) 版本的首选方法是什么？

我知道可以通过查看 HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\W3SVC\Parameters 中的 MajorVersion 键找到它。

这是否是推荐的实现方式，或者是否有任何更安全或更美观的方法可供 .NET 开发人员使用？

public int GetIISVersion()
{
     RegistryKey parameters = Registry.LocalMachine.OpenSubKey("SYSTEM\\CurrentControlSet\\Services\\W3SVC\\Parameters");
     int MajorVersion = (int)parameters.GetValue("MajorVersion");

     return MajorVersion;
}

public int GetIISVersion()
{
     RegistryKey parameters = Registry.LocalMachine.OpenSubKey("SYSTEM\\CurrentControlSet\\Services\\W3SVC\\Parameters");
     int MajorVersion = (int)parameters.GetValue("MajorVersion");

     return MajorVersion;
}

要从 IIS 进程外部识别版本，一种可能性如下...

string w3wpPath = Path.Combine(
    Environment.GetFolderPath(Environment.SpecialFolder.System), 
    @"inetsrv\w3wp.exe");
FileVersionInfo versionInfo = FileVersionInfo.GetVersionInfo(w3wpPath);
Console.WriteLine(versionInfo.FileMajorPart);

要在运行时从工作进程内部识别它...

using (Process process = Process.GetCurrentProcess())
{
    using (ProcessModule mainModule = process.MainModule)
    {
        // main module would be w3wp
        int version = mainModule.FileVersionInfo.FileMajorPart
    }
}

To identify the version from outside the IIS process, one possibility is like below...

string w3wpPath = Path.Combine(
    Environment.GetFolderPath(Environment.SpecialFolder.System), 
    @"inetsrv\w3wp.exe");
FileVersionInfo versionInfo = FileVersionInfo.GetVersionInfo(w3wpPath);
Console.WriteLine(versionInfo.FileMajorPart);

To identify it from within the worker process at runtime...

using (Process process = Process.GetCurrentProcess())
{
    using (ProcessModule mainModule = process.MainModule)
    {
        // main module would be w3wp
        int version = mainModule.FileVersionInfo.FileMajorPart
    }
}

您可以构建一个 WebRequest 并将其发送到环回 IP 地址上的端口 80，并获取服务器 HTTP 标头。

HttpWebRequest myHttpWebRequest = (HttpWebRequest)WebRequest.Create("http://127.0.0.1/");
HttpWebResponse myHttpWebResponse = null;
try
{
    myHttpWebResponse = (HttpWebResponse)myHttpWebRequest.GetResponse();
}
catch (WebException ex)
{
    myHttpWebResponse = (HttpWebResponse)ex.Response;
}
string WebServer = myHttpWebResponse.Headers["Server"];
myHttpWebResponse.Close();

不确定这是否是更好的方法，但这肯定是另一种选择。

You could build a WebRequest and send it to port 80 on a loopback IP address and get the Server HTTP header.

HttpWebRequest myHttpWebRequest = (HttpWebRequest)WebRequest.Create("http://127.0.0.1/");
HttpWebResponse myHttpWebResponse = null;
try
{
    myHttpWebResponse = (HttpWebResponse)myHttpWebRequest.GetResponse();
}
catch (WebException ex)
{
    myHttpWebResponse = (HttpWebResponse)ex.Response;
}
string WebServer = myHttpWebResponse.Headers["Server"];
myHttpWebResponse.Close();

Not sure if that's a better way of doing it but it's certainly another option.

我是这样做的（使用Powershell）：

function Validate-IISVersion([switch] $ContinueOnError = $false)
{
if ($ContinueOnError)
{ $ErrorActionPreference = "SilentlyContinue" }
else
{ $ErrorActionPreference = "Stop" }

# Using GAC to ensure the IIS (assembly) version
$IISAssembly = [System.Reflection.Assembly]::LoadWithPartialName("Microsoft.Web.Administration")
$IISVersion = $IISAssembly.GetName().Version
$IISVersionString = [string]::Format("{0}.{1}.{2}.{3}", $IISVersion.Major, $IISVersion.Minor, $IISVersion.Build, $IISVersion.Revision)
if (!$IISVersionString.Equals("7.0.0.0"))
{
    if ($ContinueOnError)
    {
        Write-Host  "`nConflicting IIS version found! [Version: $IISVersionString]`t    " -NoNewline -ForegroundColor Red
    }
    Write-Error "Conflicting IIS version found [$IISVersionString]! @ $(Split-Path $MyInvocation.ScriptName -leaf)"
    return $false
}
else
{
    return $true
}
}

I did it this way (using Powershell):

function Validate-IISVersion([switch] $ContinueOnError = $false)
{
if ($ContinueOnError)
{ $ErrorActionPreference = "SilentlyContinue" }
else
{ $ErrorActionPreference = "Stop" }

# Using GAC to ensure the IIS (assembly) version
$IISAssembly = [System.Reflection.Assembly]::LoadWithPartialName("Microsoft.Web.Administration")
$IISVersion = $IISAssembly.GetName().Version
$IISVersionString = [string]::Format("{0}.{1}.{2}.{3}", $IISVersion.Major, $IISVersion.Minor, $IISVersion.Build, $IISVersion.Revision)
if (!$IISVersionString.Equals("7.0.0.0"))
{
    if ($ContinueOnError)
    {
        Write-Host  "`nConflicting IIS version found! [Version: $IISVersionString]`t    " -NoNewline -ForegroundColor Red
    }
    Write-Error "Conflicting IIS version found [$IISVersionString]! @ $(Split-Path $MyInvocation.ScriptName -leaf)"
    return $false
}
else
{
    return $true
}
}
