c#之将 XML 中的 ebay web 服务响应转换为 C# 对象

我正在创建一个 Windows Phone 7 应用程序，我正在其中使用 Ebay 链接

http://svcs.ebay.com/services/search/FindingService/v1?OPERATION-NAME=findItemsByKeywords&SERVICE-VERSION=1.0.0&SECURITY-APPNAME=AppID&RESPONSE-DATA-FORMAT=XML&REST-PAYLOAD&keywords=harry%20potter%20phoenix

获取以下格式的项目列表

</findItemsByKeywordsResponse> 

在整个响应中，我需要仅包含标题、描述、结束时间、列表类型和当前价格的项目列表或 ObservableCollections。

最优化的编码方式是什么。我无法想到最简单的思考方式，比如直接反序列化对 C# 对象的 XML 响应。

我还没有尝试过任何代码，但我目前对如何实现这一目标感到困惑？

请您参考如下方法:

最优化？编写一个基于 XmlReader 的解析器。一种相当快速的 headless 痛方式？使用 XLinq。未经测试:

var items = XDocument.Parse(data) 
    .Elements("findItemsByKeywordsResponse") 
    .Elements("searchResult") 
    .Elements("item") 
    .Select(item => 
    { 
        var li = item.Element("listingInfo"); 
 
        return new 
        { 
            Title = (string)item.Element("title"), 
            EndTime = li != null ? (DateTime?)li.Element("endTime") : null, 
            ListingType = li != null ? (string)li.Element("listingType") : null, 
        }; 
    });
