I'm using .NET 3.5. Why am I still be getting:
does not contain a definition for 'Distinct'
with this code:
using System.Collections.Generic;
//.. . . . . code
List<string> Words = new List<string>();
// many strings added here . . .
Words = Words.Distinct().ToList();
Are you
using System.Linq;
?
Distinct
is an extension method defined in System.Linq.Enumerable
so you need to add that using statement.
And don't forget to add a reference to System.Core.dll
(if you're using VS2008, this has already been done for you).
