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
