关于WinForm的简单问题.
在一个工程中定义了两个Form:Form1,Form2. 
 在Form1中: 
 if(a) 
 { 
          Form2   NewForm=new   Form2(); 
          NewForm.Show(); 
 } 
 现在我需要Form2弹出来,Form1消失怎么办?(现在比较郁闷的就是运行后两个界面都在.)
------解决方案--------------------this.hidden();
------解决方案--------------------在Form1中添加如下的代码: 
 protected override void OnClosed(EventArgs e) 
 { 
 	base.OnClosed(e); 
 	Thread thread = new Thread(this.showform2); 
 	thread.Start(); 
 } 
 void showform2() 
 { 
 	Application.Run(new Form2()); 
 }   
 在Form2中添加如下的代码: 
 protected override void OnClosed(EventArgs e) 
 { 
 	base.OnClosed(e); 
 	Thread thread = new Thread(this.showform1); 
 	thread.Start(); 
 } 
 void showform1() 
 { 
 	Application.Run(new Form1()); 
 }   
 private void button2_Click(object sender, EventArgs e) 
 { 
 	this.Close(); 
 	Thread thread = new Thread(this.showform2); 
 	thread.Start(); 
 } 
 void showform2() 
 { 
 	Application.Run(new Form2()); 
 }
