I’m trying to learn some Linq to XML stuff, and I came across the XPathSelectElement function in XElement. This function seems to do just what I need, but for some reason, I can’t use it! Check out my code:

        XElement rootElement = XElement.Load(dataFile);         XElement parentElement = rootElement.XPathSelectElement(xPath);

I have included references to System.Xml.Linq everywhere that is needed. All the other stuff in that library that I have tried appears to be working, but XPathSelectElement doesn’t even appear in the Intellisense in visual studio.

When building the above code, I get the following error:

Error 1 ‘System.Xml.Linq.XElement’ does not contain a definition for ‘XPathSelectElement’ and no extension method ‘XPathSelectElement’ accepting a first argument of type ‘System.Xml.Linq.XElement’ could be found (are you missing a using directive or an assembly reference?)

  1. The methods you are trying to use are extension menthods. You need to include System.Xml.XPath namespace.
