//动态添加控件 并绑定事件

int tt_i = panel2.Width / 86;           
            for (int i = 0; i < 85; i++)
            {
                int TempInt = i % tt_i;//取余数，计算横坐标用。
                int TempInt2 = (int)i / tt_i;//取整数，看放置在第几行。
                Button myButton = new Button();
                myButton.Size = new Size(85, 50);
                myButton.Name = i.ToString();
                myButton.Text = i.ToString();
                myButton.Left = 0 + TempInt * 85;
                myButton.Top = 0 + TempInt2 * 50;
                this.panel2.Controls.Add(myButton);
                myButton.Click += new System.EventHandler(btn_click);//将按钮的方法绑定到按钮的单击事件中b.Click是按钮的单击事件
            }

//动态删除 控件

for (int i = panel2.Controls.Count - 1; i >= 0; i--)
