How will I use the distanceToFly in this example?

Write a method inside the Frog class named EatFly. It should take a single integer parameter named distanceToFly and return a bool value. It should return true if the frog can reach the fly with its tongue, and false otherwise.

Frog.cs 
namespace Treehouse.CodeChallenges
{
    class Frog
    {
        public readonly int TongueLength;

        public bool EatFly(distanceToFly)
           { 
            public int distanceToFly;
            bool canreach = distanceToFly < TongueLength;
            return canreach;
           }

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

When you define parameters for a method you do so by first specifying their type and then the name, in your method declaration you only specify the name, not type. You also create the distanceToFly variable again within the method which is wrong, the variable is created automatically when it is specified as a parameter. Also keywords like public and private is only used when creating field variables (variables that are part of a class) not regular variables found within a method.

Fixing those two mistakes results in this code:

namespace Treehouse.CodeChallenges
{
    class Frog
    {
        public readonly int TongueLength;

        public bool EatFly(int distanceToFly) // Specify that distanceToFly is of type int
           { 
            // Removed redundant distanceToFly declaration
            bool canreach = distanceToFly < TongueLength;
            return canreach;
           }

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

Which will allow you to pass the challenge.

he forgot <= // here is mine i wrote:

namespace Treehouse.CodeChallenges
{
    class Frog
    {
        public readonly int TongueLength;

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

        public bool EatFly(int distanceToFly)
        {
         bool valid = distanceToFly <= TongueLength;

            return valid;

        }
    }
}

moved around your code to make it easier for me to read but should be this:

namespace Treehouse.CodeChallenges
{
    class Frog
    {
        public readonly int TongueLength;

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

        public bool EatFly(int distanceToFly)
           { 
            // fixed equation
            bool canreach = distanceToFly <= TongueLength;
            return canreach;
           }      
    }
}
