大佬教程收集整理的这篇文章主要介绍了ArcGIS API for Silverlight加载google地图（后续篇），大佬教程大佬觉得挺不错的，现在分享给大家，也给大家做个参考。

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@L_696_2@变换造成的。

现将如下三个类公布出来，源码如下：
