从 C# 获取 Powershell 错误

Problem

我正在从 c# 调用 powershell 命令，但是PowerShell命令对象似乎只有属性bool HasErrors这对我没有帮助what我收到的错误。

这就是我构建 powershell 命令的方式

Library

public static class PowerSheller
{
    public static Runspace MakeRunspace()
    {
        InitialSessionState session = InitialSessionState.CreateDefault();
        Runspace runspace = RunspaceFactory.CreateRunspace(session);
        runspace.Open();

        return runspace;
    }

    public static PowerShell MakePowershell(Runspace runspace)
    {
        PowerShell command = PowerShell.Create();
        command.Runspace = runspace;

        return command;
    }
}

调用 Move-Vm cmdlet

using (Runspace runspace = PowerSheller.MakeRunspace())
{
    using (PowerShell command = PowerSheller.MakePowershell(runspace))
    {
        command.AddCommand("Move-VM");
        command.AddParameter("Name", arguments.VMName);
        command.AddParameter("ComputerName", arguments.HostName);
        command.AddParameter("DestinationHost", arguments.DestinationHostName);

        if (arguments.MigrateStorage)
        {
            command.AddParameter("IncludeStorage");
            command.AddParameter("DestinationStoragePath", arguments.DestinationStoragePath);
        }

        try
        {
            IEnumerable<PSObject> results = command.Invoke();
            success = command.HasErrors;
        }
        catch (Exception e)
        {
            Console.WriteLine(e.Message);
        }
    }
}

我原以为失败时会抛出某种异常，但它返回 0 个对象。尽管HasErrors将导致知道命令是否成功；我仍然不确定如何获取特定错误，因为没有抛出异常。

Thanks

要查看错误，请查看集合PowerShell.Streams.Error或者在你的代码中command.Streams.Error.
