Complaining about a public method creation...

Guys,

Sorry, it might be silly but I already checked a million times! I'm trying to create a public method inside the class but I'm getting an error like if the syntax is wrong, what can I be doing incorrectly?

Thanks a lot,

Emilio

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

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

The syntax error comes from the fact that you have placed the method not just inside the class, but inside the class' constructor. You can't place method declarations inside other methods/constructors (at least not using the normal method syntax).

If you move the method outside of the constructor like this:

using System.Collections.Generic;
using System.Linq;

namespace Treehouse.CodeChallenges
{ 
    public class NumberAnalysis
    { // The class begins here
        private List<int> _numbers;
        public NumberAnalysis()
        { // The class constructors begins here
            _numbers = new List<int> { 2, 4, 6, 8, 10 };

        } // The class constructors ends here

        public IEnumerable<int> NumbersGreaterThanFive()
        {
            IEnumerable<int> results = from n in _numbers where n > 5 select n;
            return results;
        }
    } // The class ends here
}

Then your code will work.
