Namespace:  System.Net.Sockets
Assembly:  System (in System.dll)

public void Connect(
	IPAddress address,
	int port
)

Parameters

address
Type: System.Net.IPAddress

The IPAddress of the host to which you intend to connect.

port
Type: System.Int32

The port number to which you intend to connect.

SocketException

An error occurred when accessing the socket. See the Remarks section for more information.

ObjectDisposedException

TcpClient is closed.

Call this method to establish a synchronous remote host connection to the specified IPAddress and port number. The Connect method will block until it either connects or fails. After connecting with the remote host, use the GetStream method to obtain the underlying NetworkStream. Use this NetworkStream to send and receive data.

NoteNote:

If you receive a 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 MSDN for a detailed description of the error.

NoteNote:

This member outputs trace information when you enable network tracing in your application. For more information, see Network Tracing.

The following code example uses an IP Address and port number to connect with a remote host.

//Uses the IP address and port number to establish a socket connection.
TcpClient tcpClient = new TcpClient ();
IPAddress ipAddress = Dns.GetHostEntry ("www.contoso.com").AddressList[0];

tcpClient.Connect (ipAddress, 11003);
      //Uses the IP address and port number to establish a socket connection.
      TcpClient* tcpClient = new TcpClient();
      IPAddress* ipAddress = Dns::Resolve(S"www.contoso.com")->AddressList[0];
	  tcpClient->Connect(ipAddress, 11003);
