在winform中重新启动该程序

1、System.Diagnostics.Process newprocess =new System.Diagnostics.Process();
     newprocess.StartInfo.FileName="NiceFood.exe";
     newprocess.Start();
     Application.Exit();
2、在窗口的closing事件中写System.Diagnostics.Process.Start("App.exe");
3、Application.ApplicationExit += new EventHandler(Application_ApplicationExit);
Application.Exit();

Application_ApplicationExit方法为：
private void Application_ApplicationExit(object sender, EventArgs e)
{
 string fileName = "具体的程序位置";
 System.Diagnostics.Process.Start(fileName);
}
