小例子（三）、winform控件的移动

28       //鼠标进入控件表面的事件MouseEnter
29       //this.ClientSize.Width 窗体宽度
30       //button2.Width 按钮的宽度
31       //设置按钮的位置： button2.Location=new Point(x,y);x,y坐标
32         private void button2_MouseEnter(object sender, EventArgs e)
33         {
34             int x = this.ClientSize.Width - button2.Width;
35             int y = this.ClientSize.Height - button2.Height;
36             Random r = new Random();
37             button2.Location=new Point(r.Next(0,x+1),r.Next(0,y+1));
38         }
