LINQ查询问题 [英] LINQ query problem

问题描述

无法在Feed中获得任何结果. feedXML包含正确的数据.

Can't get any result in feeds. feedXML has the correct data.

XDocument feedXML = XDocument.Load(@"http://search.twitter.com/search.atom?q=twitter");

var feeds = from entry in feedXML.Descendants("entry")
            select new
            {
                PublicationDate = entry.Element("published").Value,
                Title = entry.Element("title").Value
            };

我想念什么?

推荐答案

您需要在Descendents和Element方法上都指定一个名称空间.

You need to specify a namespace on both the Descendents and Element methods.

XDocument feedXML = XDocument.Load(@"http://search.twitter.com/search.atom?q=twitter");

XNamespace ns = "http://www.w3.org/2005/Atom";
var feeds = from entry in feedXML.Descendants(ns + "entry")
            select new
            {
            PublicationDate = entry.Element(ns + "published").Value,
            Title = entry.Element(ns + "title").Value
            };
