为什么从C调用PowerShell会引发System.Management.Automation.CommandNotFoundException?

powershell c#

我用这个C:

    public bool RunPowershell(string script)
    {
        RunspaceConfiguration runspaceConfig = RunspaceConfiguration.Create();

        using (Runspace runspace = RunspaceFactory.CreateRunspace(runspaceConfig))
        {
            runspace.Open();

            using (RunspaceInvoke scriptInvoker = new RunspaceInvoke(runspace))
            {
                scriptInvoker.Invoke(script);
            }
        }

        return true;
    }

要运行此脚本:

      Add-PSSnapin -name Microsoft.SystemCenter.VirtualMachineManager
      $vmm = Get-VMMServer -ComputerName "VmmComputerName"

它在Windows 2003 32位操作系统上工作正常,但在Windows 2008R2 64位操作系统上,我得到以下错误:

System.Management.Automation.CommandNotFoundException: The term 'Get-VMMServer' is not recognized as the name of a cmdlet, function, script file, or operable program. Check the spelling of the name, or if a path was included, verify that the path is correct and try again.

at System.Management.Automation.AssignmentStatementNode.Execute(Array input, Pipe outputPipe, ExecutionContext context)
at System.Management.Automation.StatementListNode.ExecuteStatement(ParseTreeNode statement, Array input, Pipe outputPipe, ArrayList& resultList,     ExecutionContext context)

而且,我已经安装了Microsoft.SystemCenter.VirtualMachineManager。如果我手动将脚本输入到2008R2计算机上的PowerShell控制台中,该脚本也可以工作。

你能为我可能遗漏的东西提供帮助吗?

非常感谢。
