我试图从中找出两个AddressLine。 我做了以下工作，但无法正常工作-

 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();

Answer 1

您忘记了包含Xml名称空间。

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();
