LINQ's Distinct() on a particular property

Question

I am playing with LINQ to learn about it, but I can\'t figure out how to use Distinct when I do not have a simple list (a simple list of integers is pretty easy

Answer 1

You can use DistinctBy() for getting Distinct records by an object property. Just add the following statement before using it:

using Microsoft.Ajax.Utilities;

and then use it like following:

var listToReturn = responseList.DistinctBy(x => x.Index).ToList();

where 'Index' is the property on which i want the data to be distinct.
