类似QQ的全套聊天系统

TCP协议数据传输和聊天程序服务器端程序源代码(TCP data and message transferring, server program.)

C语言实现的监听网络流量的程序，并对截取的报文进行分析。(C language to monitor the flow of network procedures, and analysis of the interception of the message.)

可以获取自己的ip地址，模仿cmd的ipconfig命令(Can get the ip address imitate cmd ipconfig command)

可以实现HTTP转发/HTTP请求,如果需要做一个网页下载,那么可以使用该类,该类最大的特点是支持PROXY代理下载!(HTTP can be transmitted/HTTP request, if required to do a website, then you can use this kind, the largest such feature is support PROXY proxy to download!)

IEC104服务器 实现IEC104服务器的功能(Iec104 master )

本示例主要实现了以下三点： 1. 自建了mqtt 服务端（broker）,并可以接收客户端发来的各种topic 2. 实现了客户端发布订阅mqtt消息 3. 实现了 服务端直接向外广播topic，客户端只需要 订阅该topic即可 调试步骤如下： 1. 运行>>cmd>>  cd 至 MQTTnet.TestApp.AspNetCore2 目录，并执行 dotnet run 2. 浏览器输入 http://localhost:5000 即可看到如下截图，浏览器输入 http://localhost:5000/publish 即可通过服务端发布topic

C#网络编程基础一书的所有例子，涵盖从SOCKET到加密的所有功能，值得学习(C# Network Programming, a book of all the examples, ranging from SOCKET to encrypt all the features, it is worth learning)

一个用C写的内存管理系统,模拟操作系统内存,很好不错的(A memory management system written in C, analog operating system memory, very good)

C#模拟HTTP请求实现刷票功能，自动宽带拨号断开实现换IP的目的(C# simulate HTTP requests to achieve brush votes, automatic disconnection of broadband dial to achieve the purpose for IP' s)

网络抓包与协议分析，实现图形用户界面，能利用原始套接字编程接口（winpcap）进行抓包，能对抓包的内容进行分层显示和各字段数值显示，可对抓包进行过滤，将抓包的内容存入数据库。 (Network packet capture and protocol analysis, graphical user interface, to use raw socket programming interface (winpcap) conducted capture, able to capture and display the contents of each field value hierarchical display, capture can be filtered, The capture of the content stored in the database.)
