C#高级编程（第四版）的Bug

书里在讨论到事件中使用匿名方式时举了下面三个例子：

    btnOne.Click += new EventHandler( lblInfo.Text = "button One was pressed.";);

    btnTwo.Click += new EventHandler( lblInfo.Text = "button Two was pressed.";);

    ......

可是匿名方法不是这么用的，事实上这几行代码也无法编译通过。

应该改成类似于

    this.btnEvent.Click += new System.EventHandler(delegate(object sender, EventArgs e)

        {

            MessageBox.Show("I have no name", "AnonymousMethodOfbtnEvent", MessageBoxButtons.OKCancel);

        });
