Client Object Model 是SharePoint 2010中新加的一个非常酷的功能。开发者可以从NET客户端上运行的应用程序访问SharePoint 2010，从而大大扩展了sharepoint应用。再也不必‘自古华山一条路’用web-service。
无需编写或安装SharePoint服务器上的代码。Client Object Model使我们能够建立集成的应用程序与SharePoint2010保持区隔，
Client Object Model和Object Model极为相似。

在客户端运行需要2个DLL.可以从sharepoint 2010服务器上取得
Microsoft.SharePoint.Client.dll
Microsoft.SharePoint.Client.Runtime.dll
位置：%ProgramFiles%\Common Files\Microsoft Shared\web server extensions\14\ISAPI
代码
Dim clientContext AS ClientContext = new ClientContext(siteUrl)
Dim siteCollection AS Site = clientContext.Site
Dim site AS Web = clientContext.Web
其他的和使用Object Model没有差别。
