这篇文章主要介绍“android微信公众号开发实例分析”，在日常操作中，相信很多人在android微信公众号开发实例分析问题上存在疑惑，小编查阅了各式资料，整理出简单好用的操作方法，希望对大家解答”android微信公众号开发实例分析”的疑惑有所帮助！接下来，请跟着小编一起来学习吧！
开发前说明：
我们需要用到 StreamReader
所以需要引用：using System.IO;
上面讲了一些微信给我们的规则
我们现在要用这些规则获取我们想要的东西。
第一步：获取那串 XML 这个是最重要的，因为没这个XML，我们就相当于啥都没有。（我们的信息来源就是这个XML）
这里我使用 StreamReader 来获取 Request.Body
因为XML主要是 Request.Body 里面的
计算
安全
数据库
网络和加速
企业服务
//声明一个XML方便调用
string xml="";
//获取我们的流
var reader = new StreamReader(Request.Body);
//把流里面的读取出来，就是我们这串XML了。
var contentFromBody = reader.ReadToEnd();
//再保存进我们的这个字符串里，方便后期使用
xml = contentFromBody;我们读取XML中的信息，并将其转成我们的微信信息对象。
这里呢。我借用了一位大佬的代码：
专门处理微信消息的几个类

}有了这两个类，我们的东西就好开展了，如果大家有发现报错的话，是因为string扩展类的问题。需要的留下邮箱，这个东西太长了。不好发，不过大家应该都看的懂，自己写一套也好。
使用上面第二个类中的，这个方法，进行转换 ： XmlToMessageFromWeiXin
得到我们 msg 对象
我们这个对象里面有msgtype，这个type枚举呢，就对应了各个事件。
我们写个switch就能将他们分开了。不同事件进入不同分支处理。
