ArcGIS API for Silverlight加载google地图（后续篇）

概述之前在博客中（http://blog.csdn.net/taomanman/article/details/8019687）提到的加载google地图方案，因为google地址问题，看不到图了，发现是url地址变换造成的。 现将如下三个类公布出来，源码如下：   using System;using System.Net;using System.Windows;using Syste

之前在博客中（http://blog.csdn.net/taomanman/article/details/8019687）提到的加载Google地图方案，因为Google地址问题，看不到图了，发现是URL地址变换造成的。

现将如下三个类公布出来，源码如下：
