System.Net.Sockets Namespace

The System.Net.Sockets namespace provides a managed implementation of the Windows Sockets (Winsock) interface for developers who need to tightly control access to the network.

The TCPClient, TCPListener, and UDPClient classes encapsulate the details of creating TCP and UDP connections to the Internet.

Classes

Class	Description
IPv6MulticastOption
IrDAClient	Provides connection information, and creates client connection objects for opening and closing connections to a server.
IrDADeviceInfo	Provides information about available servers and ports obtained by the client during a discovery query.
IrDAListener	Places a socket in a listening state to monitor connections from a specified service or network address.
LingerOption	Specifies whether a Socket will remain connected after a call to Close and the length of time it will remain connected, if data remains to be sent.
MulticastOption	Contains IPAddress values used for joining and dropping multicast groups.
NetworkStream	Provides the underlying stream of data for network access.
Socket	Implements the Berkeley sockets interface.
SocketException	The exception that is thrown when a socket error occurs.
TcpClient	Provides client connections for TCP network services.
TcpListener	Listens for connections from TCP network clients.
UdpClient	Provides User Datagram Protocol (UDP) network services.
