資源簡介

本文旨在用C#面向對象的方法實現P2P(Peer To Peer)(類QQ)會話系統。本文可作為學習C# P2P通信與面向對象程序設計的用例(包括所有源碼)。 一、 通信組件：System.Net.Sockets.System.Net.Sockets.UdpClient。 二、 通信原理: 利用P2P之UDP穿透Cone(錐型)NAPT原理。 三、 系統特點： 1、所有會話命令均封裝成對象。 2、每個命令對象都有Send(發送)與Exec();執行方法。Send方法用于把對象(自己)發到對方，Exec()方法完成對象的功能。 3、主要命令：Login(用戶登錄(C->S))、OnlineList(回復當前在線用戶列表(S->C))、Upline(用戶上線(S->C))、Logout(用戶登出(C->S))、Leaveline(用戶離線(C->C))、 Chat(會話(交談、閑聊)(C->C || C->S->C))Relay(服務器轉發)(C->S)、Abort(終止會話)(C->C || C->S->C)、Shutdown(停止服務)(S->S) 等。
