im really have no luck

FrogStats.cs 
namespace Treehouse.CodeChallenges
{
    class FrogStats
    {
        i = 0;
        Frog[] frogs = new Frog[i];
        public static double GetAverageTongueLength(Frog[] frogs)
        {
        for(i = 0; i < frogs.Length i++)
            {
            return frogs/frogs.Length;
            }
        }
    }
}
Frog.cs 
namespace Treehouse.CodeChallenges
{
    public class Frog
    {
        public int TongueLength { get; }

        public Frog(int tongueLength)
        {
            TongueLength = tongueLength;
        }
    }

You're getting close, here's a few hints:

  • all the code should go inside the method
  • you won't need to create a new frog instance
  • you won't want to return until after the loop finishes
  • since "frogs" is an array, you can't do math on it directly
  • you might use the loop to build up a sum of tongue lengths of all the frogs
  • after the loop, dividing the sum by the number of items in the array will give you an average
