can't figure out whats wrong with my for loop?

I think everything here is right but it keeps saying I'm wrong can someone help me figure out what I'm doing wrong?

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

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

There actually are a couple of errors as well.

First there shouldn't be a semicolon at the end of the for loop. I mean after the i++. Secondly Length is a property value for arrays so it needs to be written with a capital L. So frogs.Length is what you're looking for.

Also, not an error, but assigning frogs[i] to another variable is a bit unnecessary since you can use it in the for loop as is. frogs[i].TongueLength

There's nothing wrong with your for loop, but you need to do more than just assign the current frog to a variable. You need to add up the tongue lengths of each frog (declare a variable called 'total' or similar, and add the tongue length on each iteration of loop). Then at the end, divide total by the length of the frogs array to get the average.
