从c#中获取Powershell错误

问题

我正在从c#调用powershell命令，然而，PowerShell命令对象似乎只有属性bool HasErrors，这并不能帮助我知道我收到了什么错误。

这就是我构建powershell命令的方式

库

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);
        }
    }
}

我本以为失败时会引发某种异常，但它返回了0个对象。而HasErrors将导致知道该命令是否成功；我仍然不确定如何获得特定的错误，因为没有抛出异常。

感谢

foreach (PSObject psObject in results)
{
   ....do stuff with psObject (output to console, etc... you can use ToString() if you want)
}
