Calculating the Average Length of the frogs tongues

Can somebody help me with this?

FrogStats.cs
namespace Treehouse.CodeChallenges
{
    class FrogStats
    {
        public static double GetAverageTongueLength(Frog[] frogs)
        {
            double totalLength = 0;
            double avgLength = 0;

            for (int i=0; i <= frogs.Length; i++) 
            {
                totalLength += frogs[i];       
            }

            return totalLength / frogs.Length;
        }
    }
}
Frog.cs
namespace Treehouse.CodeChallenges
{
    public class Frog
    {
        public int TongueLength { get; }

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

It seems you forgot to access the Frogs TongueLength property, when adding them to totalLength. You can access it with dot notation

 totalLength += frogs[i].TongueLength;  

Also having the loop end when i <= frogs.Length will result in an OutOfBoundsException, due to C# being zero based. If the Length was 5 the last element will be at index 4. Trying to get index 5 will throw the error. Ending the loop when I < frogs.Length will solve it

for( int i = 0;  i < frog.Length; i++)
