System.Net.Sockets Namespace

Downloads the policy file that an instance of the Socket class will use.

Contains option values for joining an IPv6 multicast group.

Specifies whether a Socket will remain connected after a call to the Close() or Close() methods and the length of time it will remain connected, if data remains to be sent.

Contains IPAddress values used to join and drop multicast groups.

Provides the underlying stream of data for network access.

Represents an element in a SendPacketsElement array.

Implements the Berkeley sockets interface.

Represents an asynchronous socket operation.

The exception that is thrown when a socket error occurs.

Represents a policy file instance.

This class contains extension methods to the Socket class.

Provides client connections for TCP network services.

Listens for connections from TCP network clients.

A client receiver for multicast traffic from any source, also known as Any Source Multicast (ASM) or Internet Standard Multicast (ISM).

Provides User Datagram Protocol (UDP) network services.

A client receiver for multicast traffic from a single source, also known as Source Specific Multicast (SSM).

Represents a Unix Domain Socket endpoint as a path.

Presents the packet information from a call to ReceiveMessageFrom(Byte[], Int32, Int32, SocketFlags, EndPoint, IPPacketInformation) or EndReceiveMessageFrom(IAsyncResult, SocketFlags, EndPoint, IPPacketInformation).

Encapsulates the information that is necessary to duplicate a Socket.

The result of a ReceiveFromAsync(Socket, ArraySegment<Byte>, SocketFlags, EndPoint) operation.

The result of a ReceiveMessageFromAsync(Socket, ArraySegment<Byte>, SocketFlags, EndPoint) operation.

Presents UDP receive result information from a call to the ReceiveAsync() method.

Specifies the addressing scheme that an instance of the Socket class can use.

Specifies the IO control codes supported by the IOControl(Int32, Byte[], Byte[]) method.

A value that enables restriction of an IPv6 socket to a specified scope, such as addresses with the same link local or site local prefix.

Specifies the type of protocol that an instance of the Socket class can use.

Specifies the protocols that the Socket class supports.

Defines the polling modes for the Poll(Int32, SelectMode) method.

The type of asynchronous socket operation most recently performed with this context object.

Specifies the method to download a client access policy file.

Defines error codes for the Socket class.

Specifies socket send and receive behaviors.

Describes states for a Socket.

Defines socket option levels for the SetSocketOption(SocketOptionLevel, SocketOptionName, Int32) and GetSocketOption(SocketOptionLevel, SocketOptionName) methods.

Defines configuration option names.

Defines constants that are used by the Shutdown(SocketShutdown) method.

Specifies the type of socket that an instance of the Socket class represents.

The TransmitFileOptions enumeration defines values used in file transfer requests.

Represents a security critical action.
