Property should return average value in an array but won't compile?

I'm getting a CS0019 compiler error with this code. It seems as if I can't add the array elements to the sum because it doesn't think they are of type int. Do I need to call the get accessor in the Frog Class to retrieve these values?

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

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

:point_right: The type of "frogs[i]" is Frog.

On the other hand, the type of "frogs[i].TongueLength" would be int. :wink:
