Ejemplos

En el ejemplo siguiente se muestra la TreatControlCAsInput propiedad .

using namespace System;

void main()
{
   ConsoleKeyInfo cki;
   // Prevent example from ending if CTL+C is pressed.
   Console::TreatControlCAsInput = true;

   Console::WriteLine("Press any combination of CTL, ALT, and SHIFT, and a console key.");
   Console::WriteLine("Press the Escape (Esc) key to quit: \n");
   do 
   {
      cki = Console::ReadKey();
      Console::Write(" --- You pressed ");
      if((cki.Modifiers & ConsoleModifiers::Alt) != ConsoleModifiers()) Console::Write("ALT+");
      if((cki.Modifiers & ConsoleModifiers::Shift) != ConsoleModifiers()) Console::Write("SHIFT+");
      if((cki.Modifiers & ConsoleModifiers::Control) != ConsoleModifiers()) Console::Write("CTL+");
      Console::WriteLine(cki.Key.ToString());
   } while (cki.Key != ConsoleKey::Escape);
}
// This example displays output similar to the following:
//       Press any combination of CTL, ALT, and SHIFT, and a console key.
//       Press the Escape (Esc) key to quit:

//       R --- You pressed SHIFT+R 
//                --- You pressed CTL+I 
//       j --- You pressed ALT+J 
//       O --- You pressed SHIFT+O 
//       § --- You pressed CTL+U }

Comentarios

Si el valor de la TreatControlCAsInput propiedad es false y se presiona Ctrl+C, las teclas presionadas no se almacenan en el búfer de entrada y el sistema operativo finaliza el proceso que se está ejecutando actualmente. Este es el valor predeterminado.

Precaución

Utilice esta propiedad con criterio porque establecerla true en tiene un efecto tan dramático. La mayoría de los usuarios esperan ctrl+C para finalizar una aplicación de consola. Si deshabilita el efecto de Ctrl+C, el usuario debe recordar usar Ctrl+Interrumpir para finalizar la aplicación, que es una combinación de teclas menos conocida.
