我正试图找出这两个地址线。我做了以下操作，但它不工作-

 var bt = (from Main in xmlDoc.Descendants("TravelItineraryReadRS")
                  select new
                  {
                      AddressLine = string.Join(",", (from item in Main.Descendants("Hotel").Descendants("Address")
                                                      select item.Element("AddressLine").Value).ToArray()),
                  }
               ).ToList();

Linq到XML查询没有选择节点

您忘记包含Xml名称空间了。

XNamespace ns = "http://webservices.sabre.com/sabreXML/2003/07";
var bt = (from Main in xmlDoc.Descendants(ns + "TravelItineraryReadRS")
            select new
            {
                AddressLine = string.Join(",", (from item in Main.Descendants(ns + "Hotel").Descendants(ns + "Address")
                                                select item.Element(ns + "AddressLine").Value).ToArray()),
            }
    ).ToList();
