Question

我有一个C＃表单应用程序，它上面有几个按钮。我已经使用Process.start来执行一个.exe程序（一旦程序启动（onload（））就会出现这种情况）。现在我需要做的是，当用户点击表单上的特定按钮时，我需要暂停执行.exe文件，当他们点击另一个按钮时我需要恢复执行。我该怎么做？

帮助表示感谢。

    [DllImport("kernel32.dll")]

    private void SuspendProcess(int PID)
    {
      Process proc = Process.GetProcessById(PID);

      if (proc.ProcessName == string.Empty)
        return;

      foreach (ProcessThread pT in proc.Threads)
      {
        IntPtr pOpenThread = OpenThread(ThreadAccess.SUSPEND_RESUME, false, (uint)pT.Id);

        if (pOpenThread == IntPtr.Zero)
        {
          break;
        }

        SuspendThread(pOpenThread);
      }
    }

    public void ResumeProcess(int PID)
