Socket.SendTimeout Property

Definition

Namespace:

System.Net.Sockets

Assembly:

System.Net.Sockets.dll

Source:

Socket.cs

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

Property Value

Int32

The time-out value, in milliseconds. If you set the property with a value between 1 and 499, the value will be changed to 500. The default value is 0, which indicates an infinite time-out period. Specifying -1 also indicates an infinite time-out period.

Exceptions

SocketException

An error occurred when attempting to access the socket.

ObjectDisposedException

The Socket has been closed.

ArgumentOutOfRangeException

The value specified for a set operation is less than -1.

Examples

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("");
}

Remarks

This option applies to synchronous Send calls only. If the time-out period is exceeded, the Send method will throw a SocketException.
