以下是我正在阅读的XML文件的一部分：

感谢Henk Holterman，我能够清理处理XML的代码，现在我正在使用以下内容：

var doc = XDocument.Load(n);  // takes care of all Open/Close issues
strTitle = doc.Root.Element("title") == null ? "" : doc.Root.Element("title").Value;
strYear = doc.Root.Element("year") == null ? "" : doc.Root.Element("year").Value;
strPlot = doc.Root.Element("plot") == null ? "" : doc.Root.Element("plot").Value;
strRating = doc.Root.Element("rating") == null ? "" : doc.Root.Element("rating").Value;
strMPAA = doc.Root.Element("mpaa") == null ? "" : doc.Root.Element("mpaa").Value;
strCertification = doc.Root.Element("certification") == null ? "" : doc.Root.Element("certification").Value;

现在最后一点，如何使用此方法从类型元素中获取类型？我无法搜索名称元素，因为它用于各种其他元素。我不确定我是否可以合作：

doc.Root.Element("genre").ElementsAfterSelf("name");

不清楚返回的内容（我不知道如何使用IEnumberables），或者它如何处理多个“名称”。我认为它可以用LINQ完成，但我仍在试图弄清楚如何使用它。

非常感谢!!

您可以获得一系列流派：

// untested
List<string> genres = doc.Root
      .Element("genre")
      .Elements("name")
      .Select(x => x.Value).ToList();

如何使用XDocument读取多个嵌入式元素
