C# 动态事件示例

public Form1()
        {
            InitializeComponent();
            button1.Click += new EventHandler(button_Click);
            button2.Click += new EventHandler(button_Click);
            button3.Click += new EventHandler(button_Click);

        }

        private void button_Click(object sender, EventArgs e)
        {
            Button tempButton = sender as Button;
            if (tempButton != null)
                MessageBox.Show(tempButton.Text);
        } 

/*生成Button的代码*/
for(var i=; i<; i++){
    Button dynamicBtn = new Button();
    dynamicBtn.Text = string.Format("这是第{0}个按钮", i);
    dynamicBtn.Tag = i;
    dynamicBtn.Click += new EventHandler(DynamicButtonClick);
    Panel1.Controls.Add(dynamicBtn)
}

/*事件处理函数*/

private void DynamicButtonClick(object sender, EventArgs e){
    Button currentBtn = sender as Button;
    MessageBox.Show(currentBtn.Tag.ToString(), "按钮编号");
}
