public void Connect (
	String hostname,

)

Parameters

hostname

The DNS name of the remote host to which you intend to connect.

port

The port number of the remote host to which you intend to connect.

Exception typeCondition

ArgumentNullException

hostname is a null reference (Nothing in Visual Basic).

ArgumentOutOfRangeException

port is not between MinPort and MaxPort.

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 host name 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 the host name and port number to connect with a remote host.

//Uses a host name and port number to establish a socket connection.
TcpClient tcpClient = new TcpClient ();
tcpClient.Connect ("www.contoso.com", 11002);


//Uses a host name and port number to establish a socket connection.
TcpClient tcpClient = new TcpClient();
tcpClient.Connect("www.contoso.com", 11002);
