Socket.ReceiveTimeout Vlastnost

Definice

Obor názvů:

System.Net.Sockets

Sestavení:

System.Net.Sockets.dll

Zdroj:

Socket.cs

Získá nebo nastaví hodnotu, která určuje dobu, po které synchronní Receive volání vyprší časový limit.

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

public int ReceiveTimeout { get; set; }

member this.ReceiveTimeout : int with get, set

Public Property ReceiveTimeout As Integer

Hodnota vlastnosti

Int32

Hodnota časového limitu v milisekundách Výchozí hodnota je 0, což označuje nekonečné období časového limitu. Zadání -1 také označuje nekonečné období časového limitu.

Výjimky

SocketException

Při pokusu o přístup k soketu došlo k chybě.

ObjectDisposedException

Byl Socket zavřený.

ArgumentOutOfRangeException

Hodnota zadaná pro operaci sady je menší než -1.

Příklady

Následující příklad kódu ukazuje použití ReceiveTimeout vlastnosti.

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.)

Poznámky

Tato možnost platí pouze pro synchronní Receive volání. Pokud dojde k překročení časového limitu Receive , metoda vyvolá SocketExceptionchybu .
