Question

I know the GUI has

private void Form1_Closing(object sender, System.ComponentModel.EventArgs e) {   //do stuff }

But how can i do the same thing in a console application?

C#/.NET3.5

Here’s how:

// Declare the SetConsoleCtrlHandler function // as external and receiving a delegate. [DllImport('Kernel32')] public static extern bool SetConsoleCtrlHandler(HandlerRoutine Handler, bool Add);  // A delegate type to be used as the handler routine // for SetConsoleCtrlHandler. public delegate bool HandlerRoutine(CtrlTypes CtrlType);  // An enumerated type for the control messages // sent to the handler routine. public enum CtrlTypes {     CTRL_C_EVENT = 0,     CTRL_BREAK_EVENT,     CTRL_CLOSE_EVENT,     CTRL_LOGOFF_EVENT = 5,     CTRL_SHUTDOWN_EVENT }  private static bool ConsoleCtrlCheck(CtrlTypes ctrlType) {     // Put your own handler here     return true; }  ...  SetConsoleCtrlHandler(new HandlerRoutine(ConsoleCtrlCheck), true);
