近来无聊 写了一个google音乐的下载器
一个用wpf设计的google音乐下载器
刚发现，如果下载的多了，google会要求输入验证码的，那时这个程序就挂了，不灵了，嘿
安装包下载地址：
http://www.rayfile.com/zh-cn/files/32c497bd-bf13-11de-97fa-0014221b798a/
已经支持专辑批量下载及查找了
http解析方面，用了Winista的包
主要就是分析网页的html结构 用先深搜索的方式找到要分析记录的结点。
以寻找一个歌手的专辑列表为例 要顺着
<html>---
<body class="GooglePage",id="GooglePage"……
<div class="body_agent"……
这种结构一直找下去，直到找到
<div class ="results" id="album_list"
再往下进行进一步的分析，提取到相应的内容即可
这里把分析的算法提成了一个公共类
因为之前不了解BS及WPF相关的内容，中间走了不少弯路，有些代码还没有进行优化，反正我批量下载音乐（俺是80后，最喜欢周华健那个年代的歌手，故狂下之）的目的已经达到了，呵呵。
好了，不多说了，贴代码！
