Question

比如如下的VBS语句应如何改成C#的: 
strComputer = "." 
Set objWMIService = GetObject("winmgmts:" _ 
    & "{impersonationLevel=impersonate}!\\" & strComputer & "\root\cimv2")

Answer 1

    ConnectionOptions options = new ConnectionOptions();
    options.Impersonation = ImpersonationLevel.Impersonate;                          //<----
    ManagementScope scope = new ManagementScope(@"\\.\root\cimv2", options);         //<----    ObjectQuery query = new ObjectQuery("SELECT * FROM Win32_OperatingSystem");
    ManagementObjectSearcher searcher = new ManagementObjectSearcher(scope, query);    foreach (ManagementObject o in searcher.Get())
    {
        string s = "";
        foreach (PropertyData p in o.Properties)
        {
            s += p.Name + ":" + p.Value + "\n";
        }
        MessageBox.Show(s);
    }
