Accept ( ) : SocketEx	Creates the new instance of the BytesRoad.Net.Sockets.SocketEx class which represents newly created connection. Accept method accept incoming connection and create new instance of the SocketEx class for it. The SocketEx should be bound before calling this method thus you need to call BytesRoad.Net.Sockets.SocketEx.Bind and BytesRoad.Net.Sockets.SocketEx.Listen methods first (or their asynchronous versions). Web proxy doesn't able to accept incoming connection. So calling this method on the instance of the SocketEx class which is configured to work with the web proxy server (BytesRoad.Net.Sockets.ProxyType.HttpConnect proxy type) will throw the System.InvalidOperationException exception.
BeginAccept ( AsyncCallback callback, object state ) : IAsyncResult	Begins an asynchronous operation to accept an incoming connection attempt. BeginAccept method asynchronously accept incoming connection and create new instance of the SocketEx class for it. The SocketEx should be bound before calling this method thus you need to call BytesRoad.Net.Sockets.SocketEx.Bind and BytesRoad.Net.Sockets.SocketEx.Listen methods first (or their asynchronous versions). Web proxy doesn't able to accept incoming connection. So calling this method on the instance of the SocketEx class which is configured to work with the web proxy server (BytesRoad.Net.Sockets.ProxyType.HttpConnect proxy type) will throw the System.InvalidOperationException exception.
BeginBind ( SocketEx socket, AsyncCallback callback, object state ) : IAsyncResult	Begins an asynchronous binding. The BeginBind method starts an asynchronous binding request. It returns immediately and does not wait for the asynchronous call to complete. The BytesRoad.Net.Sockets.SocketEx.EndBind method is used to retrieve the results of the asynchronous call. It can be called any time after BeginBind; if the asynchronous call has not completed, EndBind will block until it completes. The behavior of the BeginBind method depends on the proxy type specified while instance of the SocketEx class constructed. Table below represents the behavior of the method for different types of proxy server. Type of proxy server Behavior of the BeginBind method BytesRoad.Net.Sockets.ProxyType.None The socket will be bound locally to the same IP address as the instance of the SocketEx class specified by socket parameter. BytesRoad.Net.Sockets.ProxyType.HttpConnect Web proxy not support binding command. The System.InvalidOperationException would be thrown. BytesRoad.Net.Sockets.ProxyType.Socks4 -or- BytesRoad.Net.Sockets.ProxyType.Socks4a -or- BytesRoad.Net.Sockets.ProxyType.Socks5 The socket will be bound at the proxy server. Port and IP address may be retrieved via BytesRoad.Net.Sockets.SocketEx.LocalEndPoint property. An instance specified by socket parameter must be connected with the remote host through physically the same proxy server as the instance of the SocketEx class on which BeginBind method are called.
BeginConnect ( EndPoint remoteEP, AsyncCallback callback, object state ) : IAsyncResult	Begins an asynchronous connection to the remote host by using specified instance of the System.Net.EndPoint class. The BeginConnect method starts an asynchronous request for a remote host connection. It returns immediately and does not wait for the asynchronous call to complete. The BytesRoad.Net.Sockets.SocketEx.EndConnect method is used to retrieve the results of the asynchronous call. It can be called any time after BeginConnect; if the asynchronous call has not completed, EndConnect will block until it completes.
BeginConnect ( string hostName, int port, AsyncCallback callback, object state ) : IAsyncResult	Begins an asynchronous connection to the remote host by using host name and port number specified. The BeginConnect method starts an asynchronous request for a remote host connection. It returns immediately and does not wait for the asynchronous call to complete. The BytesRoad.Net.Sockets.SocketEx.EndConnect method is used to retrieve the results of the asynchronous call. It can be called any time after BeginConnect; if the asynchronous call has not completed, EndConnect will block until it completes.
BeginReceive ( byte buffer, int offset, int size, AsyncCallback callback, object state ) : IAsyncResult	Begins an asynchronous receive operation. The BeginReceive method starts an asynchronous receive operation. It returns immediately and does not wait for the asynchronous call to complete. The BytesRoad.Net.Sockets.SocketEx.EndReceive method is used to retrieve the results of the asynchronous call. It can be called any time after BeginReceive; if the asynchronous call has not completed, EndReceive will block until it completes. The receive operation will not completed until the data is available for reading or error occurs. You can use the BytesRoad.Net.Sockets.SocketEx.Available property to determine if data is available for reading. When BytesRoad.Net.Sockets.SocketEx.Available is non-zero, retry the receive operation.
BeginSend ( byte buffer, int offset, int size, AsyncCallback callback, object state ) : IAsyncResult	Begins an asynchronous send operation. The BeginSend method starts an asynchronous send operation. It returns immediately and does not wait for the asynchronous call to complete. The BytesRoad.Net.Sockets.SocketEx.EndSend method is used to retrieve the results of the asynchronous call. It can be called any time after BeginSend; if the asynchronous call has not completed, EndSend will block until it completes. Send operation will not completed until all of the bytes in the buffer are sent. There is also no guarantee that the data you send will appear on the network immediately. To increase network efficiency, the underlying system may delay transmission until a significant amount of outgoing data is collected. A successful completion of the send operation means that the underlying system has had room to buffer your data for a network send.
Bind ( SocketEx socket ) : void	Associates a BytesRoad.Net.Sockets.SocketEx with local end point at the proxy server. The behavior of the Bind method depends on the proxy type specified while instance of the SocketEx class constructed.

A successful completion of the Send method means that the underlying system has had room to buffer your data for a network send.
Shutdown ( SocketShutdown how ) : void	Disables sends and receives. Calls System.Net.Sockets.Socket.Shutdown method on a socket which is used in underlying layer for communication with proxy server.
SocketEx ( ) : System	Initializes new instance of the BytesRoad.Net.Sockets.SocketEx class for direct connection. With this constructor the instance of the BytesRoad.Net.Sockets.SocketEx class would be connected to remote host directly. To force connection through the proxy server you need to use other constructor.
SocketEx ( ProxyType proxyType, string proxyServer, int proxyPort, byte proxyUser, byte proxyPassword ) : System	Initializes new instance of the BytesRoad.Net.Sockets.SocketEx class for direct connection or connection through the proxy servers. If proxy server doesn't support anonymous users and the proxyUser parameter equals to null (Nothing in Visual Basic) then the BytesRoad.Net.Sockets.SocketEx.Connect method will fail.

buffer	byte	Buffer to store the received data.
size	int	The number of bytes to receive.
리턴	int

Receive() 공개 메소드

Receives specified amount of data from the remote host and store it starting from the specified offset in the supplied buffer.

public Receive ( byte buffer, int offset, int size ) : int
buffer	byte	Buffer to store the received data.
offset	int	The location in buffer to store the received data.
size	int	The number of bytes to receive.
리턴	int

Send() 공개 메소드

Sends all data from the specified buffer to the remote host.

Send will block until all of the bytes in the buffer are sent. There is also no guarantee that the data you send will appear on the network immediately. To increase network efficiency, the underlying system may delay transmission until a significant amount of outgoing data is collected. A successful completion of the Send method means that the underlying system has had room to buffer your data for a network send.

public Send ( byte buffer ) : int
buffer	byte	Data to send.
리턴	int

Send() 공개 메소드

Sends specified amount of data to the remote host.

/// The object was disposed. /// /// buffer is a null reference (Nothing in Visual Basic). /// /// size is less than 0 or exceeds the size of buffer. /// /// An error occurred when attempting to access /// the socket which is used to complete the requested operation. ///

public Send ( byte buffer, int size ) : int
buffer	byte	Data to send.
size	int	The number of bytes to send.
리턴	int

Send() 공개 메소드

Sends specified amount of data starting from the specified position in the supplied buffer to the remote host.

public Send ( byte buffer, int offset, int size ) : int
buffer	byte	Data to send.
offset	int	The position in the data buffer at which to begin sending data.
size	int	The number of bytes to send.
리턴	int

Shutdown() 공개 메소드

Disables sends and receives.

Calls System.Net.Sockets.Socket.Shutdown method on a socket which is used in underlying layer for communication with proxy server.

/// The object was disposed. ///

public Shutdown ( SocketShutdown how ) : void
how	SocketShutdown	/// One of the /// values that specifies the operation that will no longer be allowed. ///
리턴	void

SocketEx() 공개 메소드

Initializes new instance of the BytesRoad.Net.Sockets.SocketEx class for direct connection.

With this constructor the instance of the BytesRoad.Net.Sockets.SocketEx class would be connected to remote host directly. To force connection through the proxy server you need to use other constructor.

public SocketEx ( ) : System
리턴	System

SocketEx() 공개 메소드

Initializes new instance of the BytesRoad.Net.Sockets.SocketEx class for direct connection or connection through the proxy servers.

If proxy server doesn't support anonymous users and the proxyUser parameter equals to null (Nothing in Visual Basic) then the BytesRoad.Net.Sockets.SocketEx.Connect method will fail.

public SocketEx ( ProxyType proxyType, string proxyServer, int proxyPort, byte proxyUser, byte proxyPassword ) : System
proxyType	ProxyType	/// Specifies the type of the proxy server to /// be used for communication with remote end point. /// One of the values. ///
proxyServer	string	The host name of the proxy server.
proxyPort	int	The port number of the proxy server.
proxyUser	byte	/// The user name which would be used with proxy server /// in authentication procedure. ///
proxyPassword	byte	/// The password which would be used with proxy server /// in authentication procedure. ///
