Question

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

Get-Service -ComputerName "ComputerName"

当我在Powershell上运行时，我得到了所需的输出。但是当我使用C＃尝试相同的操作时，我得到以下异常。

此线程中没有可用于运行脚本的Runspace。您可以在。的DefaultRunspace属性中提供一个 System.Management.Automation.Runspaces.Runspace类型。

我正在使用的代码是：

       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：The 检索字符串时发生以下异常：“异常使用“0”参数调用“ToString”：“没有运行空间可用于在此线程中运行脚本。你可以提供一个的DefaultRunspace属性 System.Management.Automation.Runspaces.Runspace类型。脚本块你试图调用的是：$ this.ServiceName“”---＆gt;

PowerShell版本是3。 Visual Studio版本是2010 Ultimate

在调用脚本属性时，我看起来有类似的问题。但要获得最快的数据，请尝试使用此功能。修改命令（var脚本），然后在（thing.Members [%%%%%]。Value）中放置要提取或查看的PowerShell属性。（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();
    }
}

如何为PowerShell提供C＃RunSpace？
