如何定义这些button的单击事件，请高手指教

Answer 1

加上一句btn.Click += new System.EventHandler(button_Click);你自己写个button_Click方法来处理事件，

Answer 2

button_Click的参数形如：        private void button_Click(object sender, EventArgs e)
        {
              Button me=sender as Button;//取得被点击的button对象，
        }

Answer 3

看 Form1.Designer.cs 这里系统生成的代码 // 
            // button1
            // 
            this.button1.Location = new System.Drawing.Point(-2, 155);
            this.button1.Name = "button1";
            this.button1.Size = new System.Drawing.Size(75, 23);
            this.button1.TabIndex = 1;
            this.button1.Text = "button1";
            this.button1.UseVisualStyleBackColor = true;
            this.button1.Click += new System.EventHandler(this.button1_Click);
