Client Property

TcpClient.Client Property

Gets or sets the underlying Socket.

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

public Socket Client { get; set; }

Property Value

Type: System.Net.Sockets.Socket
The underlying network Socket.

TcpClient creates a Socket to send and receive data over a network. Classes deriving from TcpClient can use this property to get or set this Socket. Use the underlying Socket returned from Client if you require access beyond that which TcpClient provides. You can also use Client to set the underlying Socket to an existing Socket. This might be useful if you want to take advantage of the simplicity of TcpClient using a pre-existing Socket.

The following code example demonstrates the use of the Client property. In this example, the receive buffer size of the underlying Socket is changed.

TcpClient client = new TcpClient();
Socket s = client.Client;

if (!s.Connected)
{
    s.SetSocketOption(SocketOptionLevel.Socket, 
                 SocketOptionName.ReceiveBuffer, 16384);
    Console.WriteLine(
        "client is not connected, ReceiveBuffer set\n");
}
else
   Console.WriteLine("client is connected");
