SharePoint Client Object Model的一个小例子

笔者想要写一段代码, 该代码在客户端运行, 用于测试SharePoint服务器端的性能.

客户端是无法访问到Server Side Object Model的, 所以除了调用Web Service, 我们还可以考虑使用SharePoint 2010中引入的Client Side Object Model.

需要的功能如下, 得到某个文档库下的所有的文件, 对Word, PPT, Excel文件分别使用调用不同的函数.

在这个例子的操作里, 我仅写了对Word文档的下载.

写这段代码的时候, 参考了很多人的文章, 在这里向他们的分享表示感谢.

我也把我的代码分享给大家, 希望能够帮助更多的人.

本例子在SharePoint 2013环境中测试通过.
