C# WMI类引用

我有以下问题： 我想使用WMI类获取登录用户的权限。 所以我试了一下：

    try
    {
        ManagementObjectSearcher searcher = new ManagementObjectSearcher("root\\CIMV2", "SELECT * FROMWin32_LoggedOnUser");
        foreach (ManagementObject queryObj in searcher.Get())
        {
            accounttype += queryObj["Antecedent"];
        }
    }
    catch
    {
        accounttype = "error";
    }

但这不起作用，因为queryObj返回对

Win32\u帐户的引用

！ 我不知道如何读取此

Win32\u帐户的值

reference

顺便说一句， 我知道还有其他方法（比如

Environment.UserName

），但我想大致了解这些尊重

谢谢！

WMI类的

Antecedent

和

Dependent

属性返回a，这是WMI类实例的唯一id，您可以访问该类的数据，创建对象的实例，然后设置从对象获得的属性

路径

试试这个样品
