TcpClient Constructor ()


The .NET API Reference documentation has a new home. Visit the .NET API Browser on to see the new experience.

Initializes a new instance of the TcpClient class.

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


This constructor creates a new TcpClient and allows the underlying service provider to assign the most appropriate local IP address and port number. You must first call the Connect method before sending and receiving data.


This constructor works only with IPv4 address types.


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

The following code example demonstrates how to use the default constructor to create a new TcpClient.

//Creates a TCPClient using the default constructor.
TcpClient^ tcpClientC = gcnew TcpClient;
