无法在C＃中使用PowerCLI命令

Question

我想在我的C＃代码中使用PowerCLI cmdlet。当我将-pssnapin添加到我的powershell对象然后从该管理单元执行命令时会引发异常。

这是我的代码的一部分：

using System.Management.Automation;
using System.Management.Automation.Runspaces;
using System.Text;
using System.Threading;
using System.Threading.Tasks;
using VMware.Vim;
using VMware.VimAutomation.ViCore.Cmdlets;
using VMware.ImageBuilder;
using VMware.ImageBuilder.Commands;
namespace EsxImageBuilder

class Program
{
    private static void Main()
    {
        RunspaceConfiguration runspaceConfig = RunspaceConfiguration.Create();
        using (Runspace runSpace = RunspaceFactory.CreateRunspace(runspaceConfig))
        {
            runSpace.Open();
            using (PowerShell powerShell = PowerShell.Create())
            {
                powerShell.Runspace = runSpace;
                powerShell.Commands.AddCommand("Add-PSSnapin").AddArgument("VMware.ImageBuilder");
                powerShell.Commands.AddScript(
                    "Add-EsxSoftwareDepot -DepotUrl https://hostupdate.vmware.com/software/VUM/PRODUCTION/main/vmw-depot-index.xml");

                IAsyncResult async = powerShell.BeginInvoke();
                while (async.IsCompleted == false)
                {
                    Thread.Sleep(1000);
                    Console.WriteLine("Working...");
                }
                Console.WriteLine("finish");
                if (powerShell.Streams.Error.Count > 0)
                {//Here is output of Exception
                   Console.WriteLine(powerShell.Streams.Error[0].ToString());
                }
                Console.ReadKey();
            }
        }
    }
}

异常的输出：

  

'VMware.ImageBuilder.Impl.IfServer'的类型初始值设定项引发了异常。
