Socket.ReceiveBufferSize Eigenschaft

Definition

Namespace:

System.Net.Sockets

Assembly:

System.Net.Sockets.dll

Quelle:

Socket.cs

Ruft einen Wert ab, der die Größe des Empfangspuffers des Socket angibt, oder legt diesen fest.

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

Int32

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

Ausnahmen

SocketException

Fehler beim Versuch, auf den Socket zuzugreifen.

ObjectDisposedException

Der Socket wurde geschlossen.

ArgumentOutOfRangeException

Der für einen set-Vorgang angegebene Wert ist kleiner als 0.

Beispiele

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

static void ConfigureTcpSocket(Socket^ tcpSocket)
{
     
    // 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
    tcpSocket->ReceiveBufferSize = 8192;
     
    // Set the timeout for synchronous receive methods to
    // 1 second (1000 milliseconds.)
    tcpSocket->ReceiveTimeout = 1000;
     
    // Set the send buffer size to 8k.
    tcpSocket->SendBufferSize = 8192;
     
    // Set the timeout for synchronous send methods
    // to 1 second (1000 milliseconds.)
    tcpSocket->SendTimeout = 1000;
     
    // Set the Time To Live (TTL) to 42 router hops.
    tcpSocket->Ttl = 42;
    Console::WriteLine("Tcp Socket configured:");
    Console::WriteLine("  ExclusiveAddressUse {0}", 
        tcpSocket->ExclusiveAddressUse);
    Console::WriteLine("  LingerState {0}, {1}", 
        tcpSocket->LingerState->Enabled,

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).
