//初始化添加按钮
btnAdd = new Button ( ) ;
btnAdd.Location = new Point ( 275 , 20 ) ;
btnAdd.Text = "添加菜单" ;
btnAdd.Click += new EventHandler ( btnAdd_Click ) ;

//初始化删除按钮
btnRemove = new Button ( ) ;
btnRemove.Location = new Point ( 275 , 60 ) ;

btnClose.Text = "退出" ;
btnClose.Click += new EventHandler ( btnClose_Click ) ;
btnClose.Size = new Size ( 100 , 30 ) ;

//在窗体中加入按钮
this.Controls.Add ( btnAdd ) ;
this.Controls.Add ( btnRemove ) ;
this.Controls.Add ( btnClose ) ;

//设置窗体的属性
this.MaximizeBox = false ;
this.MinimizeBox = false ;

// 设定本窗体的MainMenu
this.Menu = myMenu ;
this.Size = new Size ( 400 , 250 ) ;
this.CancelButton = btnClose ;
this.StartPosition = FormStartPosition.CenterScreen ;

//以下是动态加入菜单项
protected void btnAdd_Click ( object sender , EventArgs e )
