TcpListener (포트)

Question

내가 서버

하지만 파일이 서버로 전송하면, 서버는 모든 파일을받지 않습니다에 파일을 전송하거나 업로드 할 수 있습니다 클라이언트 TCP/IP를 통한 파일 공유를 만들려고 오류 C# 파일 공유를 가지고

이 내 코드

Warning 1 'System.Net.Sockets.TcpListener.TcpListener(int)' is obsolete: '"This method has been deprecated. Please use TcpListener(IPAddress localaddr, int port) instead. http://go.microsoft.com/fwlink/?linkid=14202"' 

사람이 고칠 수 내 FileSharingServer에서 오류 메시지를 받았습니다 ?? 당신이해야`networkStream.Flush()`,

TcpListener tcpListener = new TcpListener(System.Net.IPAddress.Any, port); 

Answer 1

당신이 수신 할 IP 주소와 포트를 지정해야합니다. 누군가 다른 사람도 똑같이하기로 결정할 때 당신이 끔찍한 고통의 세계에 대비하지 않는다면, 결코 '이'를 잠그지 않아야합니다.
