推荐答案

您好b $ b

试试此代码..





我使用了lamda表达式而不是理解查询。

Hi
Try this code..


I have used lamda expression instead of comprehension queries.

XDocument xdoc = XDocument.Load("xmlfile.xml");

           var lv1ss = xdoc.Descendants("Vehicle").Descendants("feature").Select(k => new
           {
               propertyid = k.Descendants("propery").Select(a => new
                   {
                       propertyid = a.Attribute("id").Value,
                       propertyname = a.Attribute("name").Value
                   }).ToList(),
               id = k.Attribute("id").Value,
               name = k.Attribute("name").Value
           }).Where(k => k.name == "car").ToList();
