实现程序自动重启

 private void btnRestart_Click(object sender, EventArgs e)
        {
            Application.ExitThread();
            Thread tmp = new Thread(new ParameterizedThreadStart(AutoRun));
            object obj = Application.ExecutablePath;
            Thread.Sleep(1);           
            tmp.Start(obj);
        }

 

private void AutoRun(object obj)
        {
            Thread.Sleep(2000);
            System.Diagnostics.Process ps = new System.Diagnostics.Process();
            ps.StartInfo.FileName = obj.ToString();
            ps.Start();
        }

 还要设置 Program 类，否则，程序会启动若干个新程序。
