怎么得到当前点击的控件的Tag值呀？

[尧月]

多个按钮有不同的tag，在同一个事件中，我要确定当前点击的按钮是哪个，怎么办？

(sender as Control).Tag

using System;
using System.Windows.Forms;

class Form1 : Form
{
  Form1()
  {
    Button btnA = new Button();
    btnA.Parent = this;
    btnA.Text   = "按钮&A";
    btnA.Tag    = "这是按钮A！";
    btnA.Click += new EventHandler(ButtonClick);

    Button btnB = new Button();
    btnB.Parent = this;
    btnB.Text   = "按钮&B";
    btnB.Top    = 30;
    btnB.Tag    = "This is Button B";
    btnB.Click += new EventHandler(ButtonClick);
  }

  void ButtonClick(object sender, EventArgs e)
  {
    // 这就是你要的：
    string tag = (sender as Control).Tag.ToString();
    MessageBox.Show(tag);
  }
  
  static void Main()
  {
    Application.Run(new Form1());
  }
}
