Generic List Distinct

Question

Hi Guys I have a list with duplicate items and would list to remove duplicates. I have tried several approaches and none of them seem to have worked. Here is my code that I have to populate the list. public class Skills { public string Name { get ; set ; } } XDocument xdoclist = XDocument .Load( new XmlNodeReader (xdoc4)); List Skills > primaryProductSkills = ( from xml in xdoclist.Elements( product_parent ).Elements( product ).Elements( comp ).Elements( skill ) select new Skills { Name = xml.Element( skill ).Value }).ToList(); Thanks

To use the Distinct() extension method you'll need to implement the IEqualityComparer interface for your Skills class. Check out this MSDN link ( http://msdn.microsoft.com/en-us/library/bb348436.aspx ) which contains an example showing how to do this for a custom class.

Thank you Vulpes. This worked and the other extension method I had worked too I just wasn't looking in the right place. Both were slightly different but with the same result. Thanks

You can select distinct skills using XPath: List primaryProductSkills = xdoclist.Elements.XPathEvaluate(product_parent/product/comp/skill/@text); By default XPath evaluates only unique elements. After this query executes List would contain only names i.e. textual values of the skill nodes. Zoran
