Specifies option names for use in the Socket.SetSocketOption(SocketOptionLevel, SocketOptionName, int) and Socket.GetSocketOption(SocketOptionLevel, SocketOptionName) methods of the System.Net.Sockets.Socket class. [Edit]

public enum SocketOptionName

Remarks

Socket options determine the behavior of an instance of the System.Net.Sockets.Socket class. Some socket options apply only to specific protocols while others apply to all types. Members of the System.Net.Sockets.SocketOptionLevel enumeration specify which protocol applies to a specific socket option. [Edit]
