wp7天氣預報源代碼（二獲取谷歌天氣數據）公布源代碼下載地址

在上一篇文章里已經介紹了這個應用

由於代碼過多，和繁雜的前台頁面效果代碼，沒辦法在博文中說明白，還有很多網友要求我公布源代碼項目。在文章的最下面我提供了源代碼的下載地址。

這個天氣預報用的是谷歌的API，我特意寫了個工具類用來解析谷歌天氣數據，本文中主要介紹這個工具類。

代碼如下：

using System.Linq;
using System.Xml.Linq;
namespace GoogleWeather
{
    public static class GoogleWeatherHelper
    {

在以后的博文里我會詳細講解這個應用UI方面的實現，畢竟這個應用亮點全在UI上面。我個人是這么理解的，因為功能代碼不是很難，UI的效果比較炫。我用了Storyboard來實現了一些效果。
