推荐答案

后代是XElement实例，而不是字符串，所以你需要选择Value属性才能得到字符串：

The Descendents are XElement instances, not strings, so you need to Select the Value property in order to get strings:

public static List<string> checksum(string cusip)
  {
      XDocument doc = XDocument.Load("SampleXML.xml");
      List<string> aacruedlist = doc.Descendants("PositionSummary")
                   .Where(item =>
                       {
                           string cus = (string)item.Element("Cusip");
                           return cus != null && cus == cusip;
                       })
                   .Descendants("AccruedInterest")
                   .Select(d => d.Value)
                   .ToList();
      return aacruedlist;
  }
