Accepts a pending connection request as an asynchronous operation.
Assembly: System (in System.dll)
[HostProtectionAttribute(SecurityAction.LinkDemand, ExternalThreading = true)] public Task<TcpClient> AcceptTcpClientAsync()
The listener has not been started with a call to Start.
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.
This operation will not block. The returned Task<TResult> object will complete after the TCP connection has been accepted.
Use the TcpClient.GetStream method to obtain the underlying NetworkStream of the returned TcpClient in the Task<TResult>. 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 or AcceptSocketAsync.
This member outputs trace information when you enable network tracing in your application. For more information, see Network Tracing in the .NET Framework.
