1.介绍

客户端模型是SharePoint 2010才提供的，可以更灵活的在任何客户端设备中操作SharePoint对象，在2007版本中没有客户端模型，2010中有三种客户端模型JavaScript，SilverLight，.NET Managed。下面是对比情况：

2.原理

当我们使用客户端模型访问SharePoint 2010服务器对象的时候，请求首先会被打包成XML格式的SharePoint对象模型，然后在由客户端发送到服务器端，在服务器端调用服务器端的对象模型，。然后得到反应结果以JSON

格式发给客户端对象模型，客户端模型在解析得到的结果，展现给前端，如下图：

3.客户端模型对象

服务器端	客户端	Javascript
Microsoft.SharePoint.SPContext	Microsoft.SharePoint.Client.ClientContext	SP.ClientContext
Microsoft.SharePoint.SPSite	Microsoft.SharePoint.Client.Site	SP.Site
Microsoft.SharePoint.SPWeb	Microsoft.SharePoint.Client.Web	SP.Web
Microsoft.SharePoint.SPList	Microsoft.SharePoint.Client.List	SP.List
Microsoft.SharePoint.SPListItem	Microsoft.SharePoint.Client.ListItem	SP.ListItem
Microsoft.SharePoint.SPField	Microsoft.SharePoint.Client.Field	SP.Field
