C# 返回用户点击按钮的枚举
C# 返回用户点击按钮的枚举,这个比较有点个性了,平时好像用的不多,返回用户单击按钮后的信息,需要进行用户单击的判断,代码如下:
DialogResult dr = MessageBox.Show("消息信息", "标题", MessageBoxButtons.YesNoCancel);
switch (dr)//使用switch语句判断用户点击了哪个按钮
{
case DialogResult.Cancel://如果按下了Cancel则执行下面的语句块
MessageBox.Show("按下了Cancel");
break;
case DialogResult.No://如果按下了No则执行下面的语句块
MessageBox.Show("按下了No");
break;
case DialogResult.Yes://如果按下了Yes则执行下面的语句块
MessageBox.Show("按下了Yes");
break;
}
