我是靠谱客的博主朴素大船，最近开发中收集的这篇文章主要介绍【C#】用Visual Studio连接ONENET物联网平台做一个简易版微信，兼带连接esp8266通讯控继电器功能前言onenet端的配置Visual Studio的编程文件，觉得挺不错的，现在分享给大家，希望可以做个参考。

概述

简易版微信

前言
onenet端的配置
Visual Studio的编程
- 主界面
- 代码

前言

这是一个期末设计。。。。时间有点赶，基本上是一天晚上做完，所以可能还有很多地方不完善，基础功能是可以互相通信聊天（微信的功能），以及可以和esp8266进行物联网通讯，控制esp8266状态。
效果图：

onenet端的配置

关于onenet的详细配置和使用方法，可以看我之前的文章：物联网开发之esp8266连接onenet控制板载小灯（一）

esp8266端的配置参考：物联网开发之esp8266连接onenet控制板载小灯

正常连接调试后的效果是这样子的：
