Linq to XML 后代元素

Question

我知道这是一个简单的问题，所以很抱歉，但我是 linq to xml 的新手，并且在以下方面遇到困难：

我有以下 XML 并试图取出所有元素，包括地址元素：

<LawCentres>
<LawCentre>
  <LawCentreID>2</LawCentreID>
  <LawCentreName>Test Law Centre</LawCentreName>
  <Address>
    <Address1>Test Address1</Address1>
    <Address2>Test Address2</Address2>
    <Address3>Test Address3</Address3>
 </Address>
</LawCentre>
<LawCentre>
  <LawCentreID>22</LawCentreID>
  <LawCentreName>Secondary Law Centre</LawCentreName>
  <Address>
    <Address1>ADDRESS11</Address1>
    <Address2>ADDRESS21</Address2>
    <Address3>ADDRESS31</Address3>
    <CountryRef>10985</CountryRef>
    <CountyRef>12116</CountyRef>
  </Address>
</LawCentre>
</LawCentres>

并且我编写了以下代码，但我在提取地址和法律中心信息时遇到了困难： XDocument lawCentres = XDocument.Load(Server.MapPath("XML\LawCentres.xml"));

        var lawCentreQuery = from c in lawCentres.Descendants("LawCentre")
                             where (int)c.Element("LawCentreID") == lawCentreID
                             select new LawCentre
                             {
                                 LawCentreName = (string)c.Element("LawCentreName"),
                                 LawCentreID = (int)c.Element("LawCentreID"),
                                 LawCentreAddressLine1 = (string)c.Element("Address1"),
                                 LawCentreAddressLine2 = (string)c.Element("Address2"),
                                 LawCentreAddressLine3 = (string)c.Element("Address3"),
                             };

有什么想法吗？

Answer 1

将(string)c.Element("Address1") 替换为(string)c.Element("Address").Element("Address1")

或

(string)c.Descendants("Address1").FirstOrDefault()
