//============或者（下面的没测试）

clossing事件中，用Process.Start启动一下自己就可以。  
   
   
  在主窗体的closing事件中，加入如下代码：  
   
  if   (   MessageBox.Show("要重新启动嘛？","提示",   MessageBoxButtons.YesNoCancel,  
  MessageBoxIcon.Question)   ==   DialogResult.Yes)  
   
  System.Diagnostics.Process.Start(System.Reflection.Assembly.GetExecutingAssembly().Location);
