两种方法：

1.用Application自带的退出方法

Application.Exit();
Application.Restart();

2.多开方法

Thread thtmp = new Thread(new ParameterizedThreadStart((obj)=>
            {
                Process ps = new Process();
                ps.StartInfo.FileName = obj.ToString();
                ps.Start();
            }));
            object appName = Application.ExecutablePath;
            Thread.Sleep(2000);
            thtmp.Start(appName);
