Beispiele

Im folgenden Beispiel wird eine Möglichkeit zum Senden einer Zeichenfolge von einem übergeordneten Prozess an einen untergeordneten Prozess mithilfe von anonymen Rohren veranschaulicht. In diesem Beispiel wird ein AnonymousPipeServerStream Objekt in einem übergeordneten Prozess erstellt, und die TransmissionMode Eigenschaft wird in der Konsole angezeigt.
