如何显示一个消息框，询问用户是否真的要退出cmd窗口?

Question

我在Windows cmd中运行了一个简单的C#控制台应用程序。 如何使其在用户单击"X"关闭按钮退出程序时显示确认消息框？ 就像在javascript中一样，confirm("Do you really want to exit??")

试试这段代码：

[DllImport("Kernel32")]
private static extern bool SetConsoleCtrlHandler(EventHandler handler, bool add);
private delegate bool EventHandler(CtrlType sig);
static EventHandler _handler;
enum CtrlType
{
CTRL_C_EVENT = 0,
CTRL_BREAK_EVENT = 1,
CTRL_CLOSE_EVENT = 2,
CTRL_LOGOFF_EVENT = 5,
CTRL_SHUTDOWN_EVENT = 6
}
private static bool Handler(CtrlType sig)
{
switch (sig)
{
case CtrlType.CTRL_C_EVENT:
case CtrlType.CTRL_LOGOFF_EVENT:
case CtrlType.CTRL_SHUTDOWN_EVENT:
case CtrlType.CTRL_CLOSE_EVENT:
DialogResult dialogResult = MessageBox.Show("Do you really want to exit??", "Title", MessageBoxButtons.YesNo);
if (dialogResult == DialogResult.Yes)
Environment.Exit(0);
return true;
default:
return false;
}
}
static void Main(string[] args)
{
_handler += new EventHandler(Handler);
SetConsoleCtrlHandler(_handler, true);
Console.ReadLine();
}
