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.
Dim lingerOption As New LingerOption(True, 10)
s.SetSocketOption(SocketOptionLevel.Socket, SocketOptionName.Linger, lingerOption)
