Socket.ReceiveTimeout 屬性

定義

命名空間:

System.Net.Sockets

組件:

netstandard.dll, System.Net.Sockets.dll

來源:

Socket.cs

取得或設定值，指定同步 Receive 呼叫逾時之前的時間長度。

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

屬性值

Int32

逾時值 (以毫秒為單位)。 預設值為 0，表示無限的逾時期間。 指定 -1 也表示無限的逾時期間。

例外狀況

SocketException

嘗試存取通訊端時發生錯誤。

ObjectDisposedException

Socket 已關閉。

ArgumentOutOfRangeException

為設定作業指定的值小於 -1。

範例

下列程式代碼範例示範 如何使用 ReceiveTimeout 屬性。

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 = new 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 {tcpSocket.ExclusiveAddressUse}");

    Console.WriteLine($"  LingerState {tcpSocket.LingerState.Enabled}, {tcpSocket.LingerState.LingerTime}");

    Console.WriteLine($"  NoDelay {tcpSocket.NoDelay}");

    Console.WriteLine($"  ReceiveBufferSize {tcpSocket.ReceiveBufferSize}");

    Console.WriteLine($"  ReceiveTimeout {tcpSocket.ReceiveTimeout}");

    Console.WriteLine($"  SendBufferSize {tcpSocket.SendBufferSize}");

    Console.WriteLine($"  SendTimeout {tcpSocket.SendTimeout}");

    Console.WriteLine($"  Ttl {tcpSocket.Ttl}");

    Console.WriteLine($"  IsBound {tcpSocket.IsBound}");

    Console.WriteLine("");
}

備註

此選項僅適用於同步 Receive 呼叫。 如果超過逾時期間，方法 Receive 會擲回 SocketException。
