需要一点关于Linq 2 xml的帮助

I have a similar scenario as this one:

我有一个类似的场景:

public class TestLinq2Xml
{
  private XElement GenerateSomeXml()
  {
     return XElement.Parse(@"<MyObject>
                                <Properties>
                                   <Name>My object 1</Name>
                                   <Position>0; 0; 0</Position>
                                </Properties>
                             </MyObject>");
  }

public void ExploreXmlNode()
{
  var xmlTree = this.GenerateSomeXml();

  var name = xmlTree.Element("MyObject").Element("Properties").Element("Name").Value;

  Console.WriteLine(name);
}

}

Ok, this is very simplified. ....but it still wont work. Any ideas on what I'm doing wrong here?

好吧,这很简单。....但它仍然不起作用。有什么想法吗?

Edit:

编辑:

Oh, almost forgot. The problem is that xmlTree.Element("MyObject") returns an empty linq sequence. Even though I clearly have a node named "MyObject".

哦,差点忘了。问题是xmlTree.Element(“MyObject”)返回一个空的linq序列。尽管我有一个名为“MyObject”的节点。

2 个解决方案

#1

The XElement.Parse returns an XElement which is the <MyObject> node. Try:-

XElement。Parse返回一个XElement，它是< object >节点。试一试:

var name = xmlTree.Element("Properties").Element("Name").Value;

var name = xmlTree.Element(“属性”).Element value(“名字”);

Besides what the previous poster suggested, you can also return an XDocument from your GenerateSomeXml() function so that your linq works.

除了前面的海报建议的之外，您还可以从GenerateSomeXml()函数返回一个XDocument，以便您的linq能够工作。

        private static XDocument GenerateSomeXml()
    {
        return XDocument.Parse(@"<MyObject>
                            <Properties>
                               <Name>My object 1</Name>
                               <Position>0; 0; 0</Position>
                            </Properties>
                         </MyObject>");
    }
