System.Diagnosties.Process p=new System.Diagnosties.Process();
p.StartInfo.FileName="cmd.exe";//要執(zhí)行的程序名稱
p.StartInfo.UseShellExecute=false;
p.StartInfo.RedirectStanderInput=true;//可能接受來自調(diào)用程序的輸入信息
p.StartInfo.RedirectStanderOutput=true;//由調(diào)用程序獲取輸出信息
p.StartInfo.CreateNoWindow=true;//不顯示程序窗口
p.Start();//啟動程序
//向CMD窗口發(fā)送輸入信息：
p.StanderInput.WriteLine("shutdown -r t 10"); //10秒后重啟（C#中可不好做哦）
//獲取CMD窗口的輸出信息：
string sOutput = p.StandardOutput.ReadToEnd();有啦以下代碼，就可以神不知鬼不覺的操作CMD啦。總之，Process類是一個非常有用的類，它十分方便的利用第三方的程序擴展了C#的功能。
