TcpListener.AcceptTcpClient Method

Accepts a pending connection request.

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

member AcceptTcpClient : unit -> TcpClient

Return Value

Type: System.Net.Sockets.TcpClient
A TcpClient used to send and receive data.

ExceptionCondition
InvalidOperationException

The listener has not been started with a call to Start.

SocketException

Use the SocketException.ErrorCode property to obtain the specific error code. When 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.

AcceptTcpClient is a blocking method that returns a TcpClient that you can use to send and receive data. Use the Pending method to determine if connection requests are available in the incoming connection queue if you want to avoid blocking.

Use the TcpClient.GetStream method to obtain the underlying NetworkStream of the returned TcpClient. The NetworkStream will provide you with methods for sending and receiving with the remote host. When you are through with the TcpClient, be sure to call its Close method. If you want greater flexibility than a TcpClient offers, consider using AcceptSocket.

NoteNote

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