AnonymousPipeServerStream.TransmissionMode Propiedad

Definición

Obtiene el modo de transmisión de canalización compatible con la canalización actual.

public:
 virtual property System::IO::Pipes::PipeTransmissionMode TransmissionMode { System::IO::Pipes::PipeTransmissionMode get(); };
public override System.IO.Pipes.PipeTransmissionMode TransmissionMode { get; }
public override System.IO.Pipes.PipeTransmissionMode TransmissionMode { [System.Security.SecurityCritical] get; }
member this.TransmissionMode : System.IO.Pipes.PipeTransmissionMode
[<get: System.Security.SecurityCritical>]
member this.TransmissionMode : System.IO.Pipes.PipeTransmissionMode
Public Overrides ReadOnly Property TransmissionMode As PipeTransmissionMode

Valor de propiedad

PipeTransmissionMode compatible con la canalización actual.

Ejemplos

En el ejemplo siguiente se muestra una manera de enviar una cadena desde un proceso primario a un proceso secundario mediante canalizaciones anónimas. En este ejemplo, se crea un AnonymousPipeServerStream objeto en un proceso primario y la TransmissionMode propiedad se muestra en la consola.
