Console.TreatControlCAsInput-Eigenschaft
Assembly: mscorlib (in mscorlib.dll)
/** @property */ public static boolean get_TreatControlCAsInput () /** @property */ public static void set_TreatControlCAsInput (boolean value)
public static function get TreatControlCAsInput () : boolean public static function set TreatControlCAsInput (value : boolean)
Nicht zutreffend.
Eigenschaftenwert
true, wenn STRG+C als normale Eingabe behandelt wird, andernfalls false.Wenn der Wert einer Get-Operation für die TreatControlCAsInput-Eigenschaft false ist und STRG+C gedrückt wird, werden die gedrückten Tasten nicht im Eingabepuffer gespeichert, und das Betriebssystem beendet den derzeit ausgeführten Prozess.
Vorsicht: |
|---|
| Verwenden Sie diese Eigenschaft mit Bedacht, da es schwerwiegende Auswirkungen hat, diese Eigenschaft auf true festzulegen. Die meisten Benutzer erwarten, dass eine Konsolenanwendung mit STRG+C beendet werden kann. Wenn Sie die Funktion von STRG+C deaktivieren, muss der Benutzer wissen, dass er zum Beenden der Anwendung STRG+UNTBR verwenden kann, was eine weniger geläufige Tastenkombination darstellt. |
Im folgenden Beispiel wird die TreatControlCAsInput-Eigenschaft veranschaulicht.
