System.Net.Sockets.TcpClient.Connect Method

Connects the client to a remote TCP host using the specified IP addresses and port number.

Syntax

public void Connect (System.Net.IPAddress[] ipAddresses, int port)

Parameters

ipAddresses
The System.Net.IPAddress array of the host to which you intend to connect.
port
The port number to which you intend to connect.

Remarks

This method is typically used immediately after a call to the System.Net.Dns.BeginGetHostAddresses(string, AsyncCallback, object) method, which can return multiple IP addresses for a single host. Call the TcpClient.Connect(System.Net.IPAddress[], int) method to establish a synchronous remote host connection to the host specified by the array of System.Net.IPAddress elements and the port number. The TcpClient.Connect(string, int) method will block until it either connects or fails. After connecting with the remote host, use the TcpClient.GetStream method to obtain the underlying System.Net.Sockets.NetworkStream. Use this System.Net.Sockets.NetworkStream to send and receive data.

Note:

If you receive a System.Net.Sockets.SocketException, use SocketException.ErrorCode to obtain the specific error code. After you have obtained this code, you can refer to the Windows Sockets version 2 API error code documentation in the MSDN library at tp://msdn.microsoft.com/library for a detailed description of the error.
