Socket.SendTimeout プロパティ

定義

同期の Send 呼び出しがタイムアウトするまでの合計時間を指定する値を取得または設定します。Gets or sets a value that specifies the amount of time after which a synchronous Send call will time out.

public:
 property int SendTimeout { int get(); void set(int value); };
public int SendTimeout { get; set; }
member this.SendTimeout : int with get, set
Public Property SendTimeout As Integer

プロパティ値

タイムアウト値 (ミリ秒)。The time-out value, in milliseconds. プロパティに 1 から 499 までの値を設定しても、その値は 500 に変更されます。If you set the property with a value between 1 and 499, the value will be changed to 500. 既定値は 0 です。タイムアウトが無期限であることを示します。The default value is 0, which indicates an infinite time-out period. -1 の指定も、タイムアウトが無期限であることを示します。Specifying -1 also indicates an infinite time-out period.

例外

ソケットへのアクセスを試行しているときにエラーが発生しました。An error occurred when attempting to access the socket.

Socket が閉じられました。The Socket has been closed.

設定操作として指定された値が -1 未満です。The value specified for a set operation is less than -1.

次のコード例は、SendTimeout プロパティの使用方法を示しています。The following code example demonstrates the use of the SendTimeout property.

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,
        tcpSocket->LingerState->LingerTime);
    Console::WriteLine("  NoDelay {0}",
        tcpSocket->NoDelay);
    Console::WriteLine("  ReceiveBufferSize {0}", 
        tcpSocket->ReceiveBufferSize);
    Console::WriteLine("  ReceiveTimeout {0}",
        tcpSocket->ReceiveTimeout);
    Console::WriteLine("  SendBufferSize {0}",
        tcpSocket->SendBufferSize);
    Console::WriteLine("  SendTimeout {0}",
        tcpSocket->SendTimeout);
    Console::WriteLine("  Ttl {0}",
        tcpSocket->Ttl);
    Console::WriteLine("  IsBound {0}",
        tcpSocket->IsBound);
    Console::WriteLine("");
}
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("");
}

注釈

このオプションは、同期 Send 呼び出しにのみ適用されます。This option applies to synchronous Send calls only. タイムアウト期間を超過すると、Send メソッドによって SocketExceptionがスローされます。If the time-out period is exceeded, the Send method will throw a SocketException.
