TcpClient.Close Method

Disposes this TcpClient instance and requests that the underlying TCP connection be closed.

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

'Declaration
Public Sub Close

The Close method marks the instance as disposed and requests that the associated Socket close the TCP connection. Based on the LingerState property, the TCP connection may stay open for some time after the Close method is called when data remains to be sent. There is no notification provided when the underlying connection has completed closing.

Calling this method will eventually result in the close of the associated Socket and will also close the associated NetworkStream that is used to send and receive data if one was created.
