[原创]C#仿QQ聊天程序(点对点无服务端, P2P)
本程序是C#仿QQ程序的精简版,做了大量优化处理,包括全新界面设计及删除部分冗余代码。QQ程序涉及简单网络通信,也是网络基础编程的好教材,包括动态分配端口,对象加密传输,消息处理,在线列表管理,UI控制,系统配置,接口设计等技术值得学习。
对话窗体,可以显示和隐藏聊天记录。
打开了5个程序实例用于测试,模仿5个不同IP的客户端。当收到消息时任务栏图标志会闪烁。
下面介绍几个核心类及接口:
1.用户在线列表接口
2.发送消息窗体接口
3.用户资料及用户连线状态信息
4. 消息定义(一个基类,及3个派生类)
程序:VS2008+DEV9.2X+SQL2005 版本v1.0
SQL连接配置:
修改debug\SystemSettings.xml 文件的ConnectionString
