entHandler(this.toolBar_ButtonClick);

protected void toolBar_ButtonClick(Object sender, ToolBarButtonClickEventArgs

e) {

// Evaluate the Button property to determine which button was clicked.
switch (toolBar.Buttons.IndexOf(e.Button)) {
case 1:
MessageBox.Show("Second button.", "The Event Information");
break;
case 2:
MessageBox.Show("third button", "The Event Information");
break;
case 3:
MessageBox.Show("fourth button.", "The Event Information");
break;
}
}


　　例子中也给窗体的close事件设计了一个事件处理器，通过重载OnClosing方法你可以接收用户点击窗体的X按钮，这样你可以取消关闭事件：

protected override void OnClosing(CancelEventArgs e) {
MessageBox.Show("Exit now.", "The Event Information");
}


　　现在我们的模板就完成了，你可以使用他开始你的WINDOWS应用程序设计。
