Distinct() with lambda?

Question

Right, so I have an enumerable and wish to get distinct values from it.

Using System.Linq, there\'s of course an extension method called Distinct<

Answer 1

If Distinct() doesn't produce unique results, try this one:

var filteredWC = tblWorkCenter.GroupBy(cc => cc.WCID_I).Select(grp => grp.First()).Select(cc => new Model.WorkCenter { WCID = cc.WCID_I }).OrderBy(cc => cc.WCID); 

ObservableCollection WorkCenter = new ObservableCollection(filteredWC);
