Console.TreatControlCAsInput Eigenschaft

Definition

Ruft einen Wert ab oder legt diesen fest, der angibt, ob die Kombination der Control-Modifizierertaste und der C-Konsolentaste (STRG+C) als normale Eingabe oder als vom Betriebssystem zu behandelnde Unterbrechung behandelt wird.

Eigenschaftswert

Beispiele

Im folgenden Beispiel wird die TreatControlCAsInput -Eigenschaft veranschaulicht.

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:

Hinweise

Wenn der Wert der TreatControlCAsInput Eigenschaft ist false und STRG+C gedrückt wird, werden die gedrückten Tasten nicht im Eingabepuffer gespeichert, und das Betriebssystem beendet den derzeit ausgeführten Prozess. Dies ist der Standardwert.

Achtung

Verwenden Sie diese Eigenschaft mit Bedacht, da das Festlegen auf true eine so dramatische Wirkung hat. Die meisten Benutzer erwarten, dass STRG+C eine Konsolenanwendung beendet. Wenn Sie die Wirkung von STRG+C deaktivieren, muss der Benutzer daran denken, strg+break zu verwenden, um die Anwendung zu beenden, was eine weniger vertraute Tastenkombination ist.
