IEnumerables code wont compile. I guess I am not catching the concept. Any pointers?

Do I have to write the query separately from the the IEnumerable. Not clicking yet.

NumberAnalysis.cs
using System.Collections.Generic;
using System.Linq;

namespace Treehouse.CodeChallenges
{
    public class NumberAnalysis
    {
        private List<int> _numbers;
         public IEnumerable<int> NumberAnalysis()
        {
            _numbers = new List<int> { 2, 4, 6, 8, 10 };
            IEnumerable<int> numbersGreaterThanFive = from n in _numbers where n > 5 select n;
            return numbersGreaterThanFive;            
        }
    }
}

You created the wrong kind of thing.

The task says to "Create a public method ...", but you created a new variable inside the class constructor.

You seem to have most of the right code, just move it into a separate method.

Wow, miss read those directions. I didn't notice that was a constructor. I thought it was telling me to add it to that method. Well, it wasn't. I am through, Thank you.
