TcpClient Constructor (String, Int32)
Initializes a new instance of the TcpClient class and connects to the specified port on the specified host.
Assembly: System (in System.dll)
This constructor creates a new TcpClient and makes a synchronous connection attempt to the provided host name and port number. The underlying service provider will assign the most appropriate local IP address and port number. TcpClient will block until it either connects or fails. This constructor allows you to initialize, resolve the DNS host name, and connect in one convenient step.
If IPv6 is enabled and the method is called to connect to a host that resolves to both IPv6 and IPv4 addresses, the connection to the IPv6 address will be attempted first before the IPv4 address. This may have the effect of delaying the time to establish the connection if the host is not listening on the IPv6 address.
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.
