我当前的 LINQ 查询和示例 XML 如下。我想做的是从 以及其他属性（如修剪、身体、品牌、型号等）中选择主要图像 url。

做这个的最好方式是什么？

这是我到目前为止所拥有的

        var users = from m in main2.Elements("object")
                    select new Inventory 
                    {
                        Make = (string)m.Element("make"),
                        Year = (string)m.Element("year"),
                        Model = (string)m.Element("model"),
                    };

您希望将image_urls节点下的对象集合投影到列表中。

这会将其投影到字符串列表中。

select new Inventory
{
    Make = (string)m.Element("make"),
    Year = (string)m.Element("year"),
    Model = (string)m.Element("model"),
    Urls = m.Element("image_urls").Elements().Select(e => (string)e.Element("url"))
};
