Spawning a legacy app in CMD window in C#

Question

0 down vote favorite

I need to run a legacy app that is run from a cmd window using the Process class. ProcessStartInfo startInfo = new ProcessStartInfo();  startInfo.FileName = "cmd.exe";  startInfo.Arguments = "/C \"C:\\UTDSys\\UTD2TCM.exe –r " + Parameters.Candidate + "\"";  startInfo.CreateNoWindow = true;  startInfo.UseShellExecute = false;    try  {      // Start the process with the info we specified.      // Call WaitForExit and then the using statement will close.      using (Process exeProcess = Process.Start(startInfo))      {          exeProcess.WaitForExit();      }  }  catch (Exception e)  {      string sMsg = "Error copying the files to " + Parameters.FullPath + ".";      HandleErrorMsg(e, sMsg);      return;  }  The process My2Com.exe should run in the background, however, I consistantly get the message that a file, used when run from the cmd line with different flags, is missing. If I run the command as indicated in a cmd window, C:\MySys\My2Com.exe –r FullyQualPath, it works as expected. I have tried several different ways to set up the Process class without success. Any suggestions would be appreciated. Thank you, Tom R.
