process.BasePriority拋出了一個類型異常'System.InvalidOperationException'

Question

當我試圖從web API本地啓動一個進程時，它啓動成功，但是當我將它託管到IIS 7.5並嘗試啓動該進程時，沒有響應我正進入（狀態。當我試圖調試安裝過程到Visual Studio，開始我看到這個錯誤進程的BaseProperty

process.BasePriority threw an Exception of Type 'System.InvalidOperationException' 

我開始一個進程來啓動一個CMD.EXE這裏調試代碼如下：

public static void Start(long campaign_id, long contact_id, string startDate, string endDate, string user) 
    { 
     try 
     { 
      //WindowStyle = ProcessWindowStyle.Hidden; 
      startInfo.FileName = "cmd.exe"; 
      startInfo.WorkingDirectory = @"C:\"; 
      startInfo.Arguments = "/c sparkclr-submit --master " + ConfigurationManager.AppSettings["SparkMaster"] + " --driver-class-path " + AppDomain.CurrentDomain.BaseDirectory + "Engine\\mysql.jar " + "--exe CmAnalyticsEngine.exe " + AppDomain.CurrentDomain.BaseDirectory + "Engine " + campaign_id + " " + contact_id + " " + startDate + " " + endDate + " " + user; 
      startInfo.CreateNoWindow = false; 
      startInfo.UseShellExecute = false; 
      startInfo.LoadUserProfile = true; 
      //startInfo.Verb = "runas"; 
      process.StartInfo = startInfo; 
      process.Start(); 
      if (!process.HasExited) 
      { 
       Console.WriteLine("process is running"); 
      } 
      else 
      { 
       Console.WriteLine("process is stopped"); 
      } 
     } 
     catch (Exception e) 
     { 
      LogWritter.WriteErrorLog(e); 
     } 
    } 

當我在本地運行時，它工作正常，但在IIS上它的打印信息進程停止。

我是否需要給權限cmd.exe從IIS啓動？如果是，那麼該怎麼做？

任何幫助將不勝感激。

感謝

此錯誤表示進程exited. - 或 - 進程還沒有開始，所以沒有進程ID。

public static void Start(long campaign_id, long contact_id, string startDate, string endDate, string user) 
{ 
    try 
    { 
     ProcessStartInfo startInfo = new ProcessStartInfo(); 
     startInfo.FileName = "cmd.exe"; 
     startInfo.WorkingDirectory = @"C:\"; 
     startInfo.Arguments = "/c sparkclr-submit --master " + ConfigurationManager.AppSettings["SparkMaster"] + " --driver-class-path " + AppDomain.CurrentDomain.BaseDirectory + "Engine\\mysql.jar " + "--exe CmAnalyticsEngine.exe " + AppDomain.CurrentDomain.BaseDirectory + "Engine " + campaign_id + " " + contact_id + " " + startDate + " " + endDate + " " + user; 
     startInfo.CreateNoWindow = false; 
     startInfo.UseShellExecute = false; 
     startInfo.LoadUserProfile = true; 
     //startInfo.Verb = "runas"; 
     Process process = new Process(); 
     process.StartInfo = startInfo; 
     process.Start(); 
     if (!process.HasExited) 
     { 
      Console.WriteLine("process is running"); 
     } 
     else 
     { 
      Console.WriteLine("process is stopped"); 
     } 
    } 
    catch (Exception e) 
    { 
     LogWritter.WriteErrorLog(e); 
    } 
} 

希望它有幫助。
