The SocketOptionLevel enumeration defines the socket option levels that can be passed to the Socket.SetSocketOption and Socket.GetSocketOption methods. SocketOptionName enumerated values are grouped by SocketOptionLevel.

The following example uses this enumeration to set socket options.

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

		// Specifies that the Socket will linger for 10 seconds after Close is called.
		LingerOption *lingerOption = new LingerOption(true, 10);
		s->SetSocketOption(SocketOptionLevel::Socket, SocketOptionName::Linger, lingerOption);
