Windows XP与Windows 7中的WaitForExit进程

Question

我有一个.net控制台在Windows 7中工作得很好但是出于某种原因，如果我在Windows XP中运行相同的代码，我收到错误信息“没有进程与此对象关联”，然后它指向到prc.WaitForExit();

代码如下：

   string path;

   path = System.IO.Path.GetDirectoryName(
           System.Reflection.Assembly.GetExecutingAssembly().GetName().CodeBase);

   Process prc = new Process();  
   prc.StartInfo.FileName = path + "\\Process2.bat";
   prc.Start();

   prc.WaitForExit();
   System.Threading.Thread.Sleep(10);
   Console.WriteLine("{0} Task Process2 completed with process ID {1} and return code {2}. ", DateTime.Now.ToString(), prc.Id, prc.ExitCode.ToString());

   System.IO.StreamWriter file =
      new System.IO.StreamWriter(logpath + "\\logfile.txt", true);
        file.WriteLine(DateTime.Now.ToString() + " Task Process2 completed with process ID " + prc.Id + " and return code " + prc.ExitCode.ToString());

  file.Close();

请帮忙。任何帮助都非常适合。
