List implements Ienumerable.

Here's an example that might shed some light on what you are trying to learn. I wrote this about 6 months

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

namespace YieldReturnTest
{
    public class PrimeFinder
    {
        private Boolean isPrime(int integer)
        {
            if (0 == integer)
                return false;

            if (3 > integer)
                return true;

            for (int i = 2; i < integer; i++)
            {
                if (0 == integer % i)
                    return false;
            }
            return true;
        }

        public IEnumerable FindPrimes()
        {
            int i;

            for (i = 1; i < 2147483647; i++)
            {
                if (isPrime(i))
                {
                    yield return i;
                }
            }
        }
    }

    class Program
    {
        static void Main(string[] args)
        {
            PrimeFinder primes = new PrimeFinder();

            foreach (int i in primes.FindPrimes())
            {
                Console.WriteLine(i);
                Console.ReadLine();
            }

            Console.ReadLine();
            Console.ReadLine();
        }
    }
}
