如何为C# RunSpace提供PowerShell？

Question

我正在尝试打印Powershell脚本的响应，该脚本显示在远程主机上运行的服务。

Get-Service -ComputerName "ComputerName"

当我在Powershell上运行这个程序时，我得到了所需的输出。但是，当我使用C#进行相同的尝试时，我会得到以下异常。

在这个线程中没有运行脚本的运行空间。您可以在System.Management.Automation.Runspaces.Runspace类型的DefaultRunspace属性中提供一个。

我使用的代码是：

       var powerShell = PowerShell.Create().AddScript(script);

        var results = powerShell.Invoke();

        foreach (var item in results)
        {
            try
            {
                Console.WriteLine(item);
            }
            catch (ExtendedTypeSystemException e)
            {
                Console.WriteLine(e);
                break;
            }
        }

编辑: PowerShell中的输出

使用C#输出

System.Management.Automation.ExtendedTypeSystemException:以下异常是在检索字符串时发生的：“异常调用带有"0”参数的"ToString“：”此线程中没有运行脚本可用的运行空间。您可以在System.Management.Automation.Runspaces.Runspace类型的DefaultRunspace属性中提供一个。您试图调用的脚本块是：$this.ServiceName"“->

PowerShell版本为3，Visual版本为2010终极版

看来我在调用脚本属性时遇到了类似的问题。但是要想得到你要找的最快的数据，试试这个。修改命令(var脚本)，然后将(thing.Members%%%%%.Value)放在要拉或查看的PowerShell属性的位置。(见下文)

class Program
{
    static void Main(string[] args)
    {
        var script = "Get-NetIPAddress ";

        var powerShell = PowerShell.Create().AddScript(script).Invoke();

        foreach (var thing in powerShell)
        {
            try
            {
                //the Members must be PROPERTIES of the PowerShell object
                var name = (thing.Members["InterfaceAlias"].Value);
                var ip= (thing.Members["IPv4Address"].Value);

                Console.WriteLine("Connection: " + name + " .......... IP: " + ip);
            }
            catch
            {

            }

        }

        Console.Read();
    }
}
