如何从C#运行PowerShell作为管理员?

我想通过C#执行一些PowerShell脚本,但它需要管理员权限。这是我的代码(我得到了here):

using (new Impersonator("user", "domain", "password"))
{
    // create Powershell runspace
    Runspace runspace = RunspaceFactory.CreateRunspace();

    // open it
    runspace.Open();

    // create a pipeline and feed it the script text
    Pipeline pipeline = runspace.CreatePipeline();
    pipeline.Commands.AddScript(scriptText);

    // add parameters if any
    foreach (var parameter in parameters)
    {
        pipeline.Commands[0].Parameters.Add(parameter.Key, parameter.Value);
    }

    // add an extra command to transform the script
    // output objects into nicely formatted strings

    // remove this line to get the actual objects
    // that the script returns. For example, the script

    // "Get-Process" returns a collection
    // of System.Diagnostics.Process instances.
    pipeline.Commands.Add("Out-String");

    // execute the script
    Collection<PSObject> results = pipeline.Invoke();

    // close the runspace
    runspace.Close();

    // convert the script result into a single string
    StringBuilder stringBuilder = new StringBuilder();
    foreach (PSObject obj in results)
    {
        stringBuilder.AppendLine(obj.ToString());
    }

    return stringBuilder.ToString();
}

无论如何,这在我的机器上不起作用。例如,如果脚本文本为“Set-ExecutionPolicy Unrestricted”,那么我会收到“Access to the registry key 'HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\PowerShell\1\ShellIds\Microsoft.PowerShell' is denied.

就我而言,它无法通过Get-VM命令获取虚拟机列表。 (我发现Get-VM只有在管理员权限下运行时才返回结果。)

我做错了吗?这个问题还有另一种解决方案吗?

答案 0 :(得分:3)

这将以管理员身份启动PowerShell:

var newProcessInfo = new System.Diagnostics.ProcessStartInfo();
newProcessInfo.FileName = @"C:\Windows\SysWOW64\WindowsPowerShell\v1.0\powershell.exe";
newProcessInfo.Verb = "runas";
System.Diagnostics.Process.Start(newProcessInfo);

如果您需要传入要运行的脚本,请使用:

newProcessInfo.Arguments = @"C:\path\to\script.ps1";
