[c#]asp.net开发微信公众平台(3)微信消息封装及反射赋值

上一篇已经搭建好整体框架，实现了入口的验证，   验证通过后就交给LookMsgType方法处理，LookMsgType方法主要是对微信发来的不同的消息进行分解，不同的类型交给业务逻辑层不同的方法处理，   对不同类型的消息判断，可以用if，也可以用switch   一般来说超过5个的if用switch会更好， 这里贴出LookMsgType方法：

public void LookMsgType(string msgType)
        {

            #region 判断消息类型
            switch (msgType)
            {
                case "text":
                    RText mText = new RText();
                    mText = ReadXml.GetModel(mText, xmlModel);
                    BLLWei.DoText(dbHome, mText);//文本消息
                    break;
                case "image":
                    RImg mImg = new RImg();
                    mImg = ReadXml.GetModel(mImg, xmlModel);
                    BLLWei.DoImg(dbHome,mImg);//图片
                    break;
                case "voice": //声音
                    RVoice mVoice = new RVoice();
                    mVoice = ReadXml.GetModel(mVoice, xmlModel);
                    BLLWei.DoVoice(dbHome,mVoice);
                    break;

                case "video"://视频
                    RVideo mVideo = new RVideo();
                    mVideo = ReadXml.GetModel(mVideo, xmlModel);
                    BLLWei.DoVideo(dbHome, mVideo);
                    break;

                case "location"://地理位置
                    RLocation mLocation = new RLocation();

                    BLLWei.DoLink(dbHome,mLink);
                    break;
                #region 事件
