sharepoint-2010 - 可查询负载如何在 SharePoint 中工作？

Question

当 LINQ 用于检索 SharePoint 对象时，任何人都可以帮助我了解幕后的工作类型。对于 example ，我可以使用这样的代码:

private IEnumerable<List> newLists;

var dt = new DateTime(2010, 3, 20);
var query = from list
            in clientContext.Web.Lists
            where list.Created > dt && list.Hidden == false
            select list;

newLists = clientContext.LoadQuery(query);
clientContext.ExecuteQuery();

它是如何工作的？

请求看起来如何？

来自 documentation我发现:

When you use the CSOM, you can write LINQ queries against client-side objects, such as lists and Webs, and then use the ClientContext class to submit these queries to the server. It's important to understand that when you take this approach, you are using LINQ to Objects to query SharePoint objects, not LINQ to SharePoint. This means that your LINQ expressions are not converted to CAML and you will not see the performance benefits that are associated with CAML conversion.

所以，我有点困惑，因为我认为，LINQ 表达式转换为 Caml 请求。我无法理解它是如何工作的。如何在执行 ExecuteQuery() 时查看请求的详细信息方法？你能向我推荐任何观看请求的工具吗？

SP 在内部使用 CAML:SP 运行时将 Linq 转换为 CAML 并通过 Soap 请求或 REST 语句(如果您使用的是 RESTful 服务)发送:http://msdn.microsoft.com/en-us/library/ff798339.aspx (有例子)；
