process.BasePriority抛出了一个类型异常'System.InvalidOperationException'

Question

当我试图从web API本地启动一个进程时，它启动成功，但是当我将它托管到IIS 7.5并尝试启动该进程时，没有响应我正进入（状态。当我试图调试安装过程到Visual Studio，开始我看到这个错误进程的BaseProperty

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

我开始一个进程来启动一个CMD.EXE这里调试代码如下：

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); 
     } 
    } 

当我在本地运行时，它工作正常，但在IIS上它的打印信息进程停止。

我是否需要给权限cmd.exe从IIS启动？如果是，那么该怎么做？

任何帮助将不胜感激。

感谢

此错误表示进程exited. - 或 - 进程还没有开始，所以没有进程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); 
    } 
} 

希望它有帮助。
