)
public void SetSocketOption (

Not applicable.

Parameters

optionLevel

One of the SocketOptionLevel values.

optionName

One of the SocketOptionName values.

optionValue

An array of type Byte that represents the value of the option.

Exception typeCondition

SocketException

An error occurred when attempting to access the socket. See the Remarks section for more information.

ObjectDisposedException

The Socket has been closed.

Socket options determine the behavior of the current Socket. Use this overload to set those Socket options that require a byte array as an option value.

NoteNote:

If you receive a SocketException, use the SocketException.ErrorCode property to obtain the specific error code. After you have obtained this code, refer to the Windows Sockets version 2 API error code documentation in the MSDN library for a detailed description of the error.

NoteNote:

This member outputs trace information when you enable network tracing in your application. For more information, see Network Tracing.

Windows 98, Windows NT 4.0 Platform Note: You must call the Bind method before using AddMembership as the optionName parameter.

Windows Mobile 2003 for Pocket PC, Windows Mobile 2003 for Smartphone, Windows CE Platform Note: Not all socket options are supported on the .NET Compact Framework. For a list of options reserved for future use, see SocketOptionName.

The following code example sets the LingerOption and Send time-out values.

// Send operations will time-out if confirmation 
// is not received within 1000 milliseconds.
s.SetSocketOption (SocketOptionLevel.Socket, SocketOptionName.SendTimeout, 1000);

// The socket will linger for 10 seconds after Socket.Close is called.
LingerOption lingerOption = new LingerOption (true, 10);

s.SetSocketOption (SocketOptionLevel.Socket, SocketOptionName.Linger, lingerOption);


// Send operations will time-out if confirmation 
// is not received within 1000 milliseconds.
s.SetSocketOption(SocketOptionLevel.Socket, 
    SocketOptionName.SendTimeout, 1000);
// The socket will linger for 10 seconds after Socket.Close is called.
LingerOption lingerOption = new LingerOption(true, 10);

s.SetSocketOption(SocketOptionLevel.Socket, SocketOptionName.Linger, 
    lingerOption);
