  1. 如何通过CAML查询一个View里面的数据。

服务器端的API支持输入View的ID:

客户端的API则不支持:

SharePoint CAML Query小结-LMLPHP

需要用如下的方法进行查询:

Public
ListItemCollection
GetSPItems(listName, viewName){

 

ClientContext context = new
ClientContext("http://SiteUrl");

 

List list1 = context.Web.Lists.GetByTitle(listName);

 

View view = list1.Views.GetByTitle(viewName);

clientContext.Load(view);

clientContext.ExecuteQuery();

CamlQuery query = new
CamlQuery();

camlQuery.ViewXml = view.ViewQuery;

ListItemCollection items = announcementsList.GetItems(query);

 

context.Load(items);

context.ExecuteQuery();

retun items;

 

}

 

//Example of usage:

 

ListItemCollection listItems = GetSPItems("Tasks", "My Tasks");
