从C#调用远程powershell命令

Question

我正在尝试使用C#运行invoke-command cmdlet,但我无法找出正确的语法.我只想运行这个简单的命令:

invoke-command -ComputerName mycomp.mylab.com -ScriptBlock {"get-childitem C:\windows"}

在C#代码中,我完成了以下操作:

InitialSessionState initial = InitialSessionState.CreateDefault();
Runspace runspace = RunspaceFactory.CreateRunspace(initial);
runspace.Open();
PowerShell ps = PowerShell.Create();
ps.Runspace = runspace;
ps.AddCommand("invoke-command");
ps.AddParameter("ComputerName", "mycomp.mylab.com");
ps.AddParameter("ScriptBlock", "get-childitem C:\\windows");
foreach (PSObject obj in ps.Invoke())
{
   // Do Something
}

当我运行它时,我得到一个例外:

Cannot bind parameter 'ScriptBlock'. Cannot convert the "get-childitem C:\windows" value of type "System.String" to type "System.Management.Automation.ScriptBlock".

我猜我需要在某处使用ScriptBlock类型,但不知道该怎么做.这只是一个简单的示例,真正的用例将涉及运行一个包含多个命令的更大的脚本块,因此任何有关如何执行此操作的帮助都将受到高度赞赏.

谢谢

啊,ScriptBlock本身的参数需要是ScriptBlock类型.

完整代码:

InitialSessionState initial = InitialSessionState.CreateDefault();
Runspace runspace = RunspaceFactory.CreateRunspace(initial);
runspace.Open();
PowerShell ps = PowerShell.Create();
ps.Runspace = runspace;
ps.AddCommand("invoke-command");
ps.AddParameter("ComputerName", "mycomp.mylab.com");
ScriptBlock filter = ScriptBlock.Create("Get-childitem C:\\windows");
ps.AddParameter("ScriptBlock", filter);
foreach (PSObject obj in ps.Invoke())
{
   // Do Something
}
