LINQ通过C＃XML [英] LINQ to XML via C#

问题描述

我是新来的LINQ。我理解它的目的。但我不能完全弄清楚。我有一个XML集如下所示：

I'm new to LINQ. I understand it's purpose. But I can't quite figure it out. I have an XML set that looks like the following:

<Results>
  <Result>
    <ID>1</ID>
    <Name>John Smith</Name>
    <EmailAddress>[e-mail]</EmailAddress>
  </Result>
  <Result>
    <ID>2</ID>
    <Name>Bill Young</Name>
    <EmailAddress>[e-mail]</EmailAddress>
  </Result>
</Results>

我已加载这个XML到一个XDocument这样：

I have loaded this XML into an XDocument as such:

string xmlText = GetXML();
XDocument xml = XDocument.Parse(xmlText);

现在，我想要得到的结果为POCO格式。在努力做到这一点，我目前使用的：

Now, I'm trying to get the results into POCO format. In an effort to do this, I'm currently using:

var objects = from results in xml.Descendants("Results")
              select new Results
              // I'm stuck

我如何通过得到的结果LINQ元素的集合？我特别困惑，在我的代码，这一点导航XML结构。

How do I get a collection of Result elements via LINQ? I'm particularly confused about navigating the XML structure at this point in my code.

感谢您！

推荐答案

这将返回一个的IEnumerable 匿名类的：

This will return a IEnumerable of anonymous class:

var q = from result in xml.Descendants
        select new
        {
            ID = result.Descendants("ID"),
            Name= result.Descendants("Name"),
            EmailAddress= result.Descendants("EmailAddress")
        };

如果您已经定义的类'结果，例如：

or if you have defined class `Result, e.g.:

class Result
{
    public ID { get; set; }
    public Name { get; set; }
    public EmailAddress { get; set; }
}

然后：

then:

var q = from result in xml.Descendants
        select new Result
        {
            ID = result.Descendants("ID"),
            Name = result.Descendants("Name"),
            EmailAddress = result.Descendants("EmailAddress")
        };

（返回的IEnumerable<结果> ）
