私のitems変数は count: 0 です 理由がよくわかりません.xdocにはxmlファイルが含まれていますitems. ここで何か間違ったことをしていますか？

                var url = "http://sample.com/test.xml";
                var xdoc = XDocument.Load(url);
                var items = xdoc.Descendants("item")
                .Select(item => new
                {
                    Title = item.Element("title").Value,
                    Description = item.Element("description").Value,
                    Link = item.Element("link").Value,
                    PubDate = item.Element("dc:date").Value,
                    MyImage = item.Element("content:encoded").Value

                })
                .ToList();

これは、xml ファイルがどのように見えるかです。そこからスニピットを取得しただけです。さらに項目があります。

    <description>Compared to recent Apple announcements, the secrecy surrounding the next release of the company's mobile operating system, iOS 7, has almost been hermetic.

            Compared to recent Apple announcements, the secrecy surrounding the next release of the company's mobile operating system, iOS 7, has almost been hermetic. There have been reports of improvements in email and calendar apps, as well as a possible expansion of the operating systems' gesture library so it will match Apple's OS X products. Apple is working feverishly to get iOS 7 ready for its app makers in June, when it will host its annual Worldwide Developers Conference.

    <title>Adobe Photoshop Touch Is Almost Picture Perfect</title>

    <description>With tablets possibly on track to overtake PCs within a few years, one might wonder just how that's going to happen. Can tablets really perform as well as PCs in professional environments? I for one am still unpacking my laptop when it comes to power applications like imaging. Well, Adobe claims it now delivers its core Adobe Photoshop functionality in an app for Android tablets.</description>

            Can tablets really perform as well as PCs in professional environments? I for one am still unpacking my laptop when it comes to power applications like imaging. Well, Adobe claims it now delivers its core Adobe Photoshop functionality in an app for Android tablets -- and looking at the feature specs, it might be on to something. I decided to take expensive Adobe Photoshop Touch out for a hard-nosed run, and I wasn't just going to be fixing a few vacation snaps.

The mining was surreptitiously set in motion by a rogue employee without the knowledge of other ESEA staff or users of the network. ESEA is known for anti-cheat software and systems that allow players to compete in online matches. Cofounder Eric 'Ipkane' Thunberg acknowledged the incident, which ironically occurred through the use of the anti-cheat software.

これは、xml ファイルの先頭にあります。

あなたはこのようにしなければなりません

var url = @"http://www.technewsworld.com/perl/syndication/rssfull.pl";
var xdoc = XDocument.Load(url);
var v = xdoc.Descendants().Where(e => e.Name.LocalName == "item");
var items = v.Select(item => new
            {
                Title = item.Descendants().Where(e => e.Name.LocalName == "title").First().Value,
                Description = item.Descendants().Where(e => e.Name.LocalName == "description").First().Value,
                Link = item.Descendants().Where(e => e.Name.LocalName == "link").First().Value,
                //PubDate = item.Descendants().Where(e => e.Name.LocalName == "dc:date").First().Value,
                //MyImage = item.Descendants().Where(e => e.Name.LocalName == "content:encoded").First().Value,
            })
            .ToList();
