1,241 PointsC# CS0120 - non-static member reference error
I review the answer on another CS0120 error question, but I'm not following it. The variable name is exactly the same as the private variable I set as a double before the method. I originally thought this was because I was trying to reference the "Frog" property "TongueLength", but when I removed that code, it looks like its just the name of the variables I'm using. I'm getting the below error on all of the variables I'm calling.
error CS0120: An object reference is required to access non-static member `Treehouse.CodeChallenges.FrogStats._totalTongueLength'
Sorry, I thought it was downloaded with the question. Odd, pretty sure I checked that. In any event, see below:
FROG STATS CLASS
namespace Treehouse.CodeChallenges { class FrogStats { private int _tongueLength; private int _sumOfTongueLength; private double _avgTongueLength; private int _numberOfFrogs;
public static double GetAverageTongueLength(Frog[] frogs)
{
for (int i = 0; i < frogs.Length; i++)
{
Frog frog = frogs[i];
_tongueLength = frog.TongueLength;
_sumOfTongueLength = _tongueLength + _sumOfTongueLength;
}
_numberOfFrogs = frogs.Length += 1;
_avgTongueLength = _sumOftongueLength /= _numberOfFrogs;
}
}
}
FROG CLASS
namespace Treehouse.CodeChallenges { public class Frog { public int TongueLength { get; }
public Frog(int tongueLength)
{
TongueLength = tongueLength;
}
}
}
For some reason it isn't formatting the first couple lines of code properly?!

1,241 Pointsok, looks like I just needed to add "static" in front of the field type that took care of the CS0120 error.
