得到这个奇怪的 LINQ 错误。
标题 = System.Linq.Enumerable+WhereSelectEnumerableIterator`2[System.Xml.Linq.XElement,System.String
这是我的代码:
if (Request.QueryString["Keywords"] != null){
string keywords = Request.QueryString["Keywords"];
string myAppID = "HIDDEN";
var xml = XDocument.Load("http://svcs.ebay.com/services/search/FindingService/v1?OPERATION-NAME=findItemsByKeywords&SERVICE-VERSION=1.0.0&SECURITY-APPNAME=" + myAppID + "&RESPONSE-DATA-FORMAT=XML&REST-PAYLOAD&keywords=" + keywords + "&paginationInput.entriesPerPage=5");
XNamespace ns = "http://www.ebay.com/marketplace/search/v1/services";
var titles = from item in xml.Root.Descendants(ns + "title")
select new{
title = xml.Descendants(ns + "title").Select (x => x.Value),
};
foreach (var item in titles){
Label1.Text += item;
}
}
XML 如下所示:
<findItemsByKeywordsResponse xmlns="http://www.ebay.com/marketplace/search/v1/services">
<searchReslut count="5">
<item>
<title></title>
</item>
<item>
<title></title>
</item>
<item>
<title></title>
</item>
试图让它正确输出。
