WMI Win32_OperatingSystem OSArchitecture 字段导致异常

发布于 2024-08-26 02:02:44 字数 768 浏览 0 评论 0原文

我正在尝试从 WMI 获取有关安装的 Windows 版本的信息。大多数领域都有效。我可以获得操作系统“名称”和“版本”，两者都是我拥有的 Win32_OperatingSystem 对象的字段。

但另一个字段“OSArchitecture”生成异常（“未找到”）。

    strScope = "\\" + strServer + "\root\CIMV2"
    searcher = New ManagementObjectSearcher(strScope, "SELECT * FROM Win32_OperatingSystem")

    For Each mo In searcher.Get

        strOSName = mo("Name")
        strOSVersion = mo("Version")
        strOSArchitecture = mo("OSArchitecture")
        strStatus = mo("Status")
        strLastBoot = mo("LastBootUpTime")

    Next

该文档说该字段应该存在并且是一个字符串：

有什么想法吗？

I am trying to get information on the version of Windows installed from WMI. Most fields work. I can get the operating system "Name" as well as the "Version", both are fields of the Win32_OperatingSystem object I have.

But another field "OSArchitecture" generates an exception ("Not found").

    strScope = "\\" + strServer + "\root\CIMV2"
    searcher = New ManagementObjectSearcher(strScope, "SELECT * FROM Win32_OperatingSystem")

    For Each mo In searcher.Get

        strOSName = mo("Name")
        strOSVersion = mo("Version")
        strOSArchitecture = mo("OSArchitecture")
        strStatus = mo("Status")
        strLastBoot = mo("LastBootUpTime")

    Next

The documentation says that the field ought to exist and is a String:

http://msdn.microsoft.com/en-us/library/aa394239(VS.85).aspx

Any ideas?

您最初的问题有这样一行：

strOSArchitecture = mo("Architecture")

应该是：

strOSArchitecture = mo("OSArchitecture")

现在您已经确认这是问题中的一个简单拼写错误（不是您的实际代码），另一种可能性是您正在服务器 2003、2000、NT4、 XP 或 Me/98/95，其中文档将 OSArchitecture 键列为不可用？

Your original question had the line:

strOSArchitecture = mo("Architecture")

which should have been:

strOSArchitecture = mo("OSArchitecture")

Now that you've confirmed that was a simple typo in the question (not your actual code), the other likelihood is that you are running on either Server 2003, 2000, NT4, XP or Me/98/95, where the documentation lists the OSArchitecture key as unavailable?

要查看可用属性的当前（运行时）列表，请查看 Properties 属性。
在控制台应用程序中，它看起来像：

For Each mo In searcher.Get
    Console.WriteLine("..." + mo.Properties.Count.ToString() + " properties")
    For Each prop In mo.Properties
        Console.WriteLine(prop.Name)
    Next
    '...

在我的 XP 安装中，列出的 61 个属性名称中没有出现 OSArchitecture。

To view a current (runtime) list of available properties, walk the Properties attribute.
In a console application, it looks like:

For Each mo In searcher.Get
    Console.WriteLine("..." + mo.Properties.Count.ToString() + " properties")
    For Each prop In mo.Properties
        Console.WriteLine(prop.Name)
    Next
    '...

On my XP installation, no OSArchitecture appears in the 61 property names listed.
