Socket.ReceiveBufferSize Eigenschaft

public:
 property int ReceiveBufferSize { int get(); void set(int value); };

public int ReceiveBufferSize { get; set; }

member this.ReceiveBufferSize : int with get, set

Public Property ReceiveBufferSize As Integer

Eigenschaftswert

Ein Int32, das die Größe des Empfangspuffer in Bytes enthält. Der Standardwert hängt vom Betriebssystem ab.

Beispiele

Im folgenden Codebeispiel wird die Verwendung des ReceiveBufferSize-Attributs veranschaulicht.

    // Don't allow another socket to bind to this port.
    tcpSocket->ExclusiveAddressUse = true;
     
    // The socket will linger for 10 seconds after
    // Socket.Close is called.
    tcpSocket->LingerState = gcnew LingerOption(true, 10);
     
    // Disable the Nagle Algorithm for this tcp socket.
    tcpSocket->NoDelay = true;
     
    // Set the receive buffer size to 8k

Hinweise

Eine größere Puffergröße reduziert möglicherweise die Anzahl leerer Bestätigungen (TCP-Pakete ohne Datenteil), kann aber auch die Erkennung von Verbindungsprobleme verzögern. Erwägen Sie, die Puffergröße zu erhöhen, wenn Sie große Dateien übertragen oder eine Verbindung mit hoher Bandbreite und hoher Latenz verwenden (z. B. einen Satelliten-Breitbandanbieter).
