[Solved] Can't seem to figure this one out and don't find solution to challenge 2 of 2

How to make this right?

Because I cant seem to understand whats wrong with this.

namespace Treehouse.CodeChallenges
{
    class Frog
    {
        private GetNumFliesEaten _numFliesEaten;

        public int GetNumFliesEaten GetValue()
        {
            return _numFliesEaten;
        }

        public void SetNumFliesEaten(GetNumFliesEaten value)
        {
            _numFliesEaten = value;
        }
    }
}

namespace Treehouse.CodeChallenges
{
    class Frog
    {
        private GetNumFliesEaten _numFliesEaten;

        public int GetNumFliesEaten GetValue()
        {
            return _numFliesEaten;
        }

        public void SetNumFliesEaten(GetNumFliesEaten value)
        {
            _numFliesEaten = value;
        }
    }
}

This is your code. It look really neat! Two problems, though. One, there's no use to say GetValue() in "public int GetNumFliesEaten GetValue()" . Try getting rid of that GetValue(). Second, you called the parameter for SetNumFliesEaten value, which is a reserved keyword in C#. "value" is like a built-in reserved word in C#, just like how "public" and "void" are. You cannot use them as variable names, or it will cause an error. instead, try giving it a different name that isn't a reserved word. I'm going to use "val" as the new name, but you can call it whatever you want. Otherwise, I really like your code!

EDIT: Also, val's type should be a int, not a GetNumFliesEaten!

Here's the solution (please read the text above this first, please please! :smile:):

namespace Treehouse.CodeChallenges
{
    class Frog
    {
        private GetNumFliesEaten _numFliesEaten;

        public int GetNumFliesEaten()
        {
            return _numFliesEaten;
        }

        public void SetNumFliesEaten(int val)
        {
            _numFliesEaten = val;
        }
    }
}

Hope this helps! ~Alex ;smile:

Seems to me that value is a contextual keyword :( https://msdn.microsoft.com/en-us/library/x53a06bb.aspx

Try a different variable name. Otherwise your code looks sharp (hehehe) to me!

Bummer! Your code could not be compiled. Please click on "Preview" to view the compiler errors.

Frog.cs(5,17): error CS0246: The type or namespace name `GetNumFliesEaten' could not be found. Are you missing an assembly reference? Compilation failed: 1 error(s), 0 warnings

Got it! Here is what worked for me :)

namespace Treehouse.CodeChallenges { public class Frog { private int _numFliesEaten;

    public int GetNumFliesEaten()
    {
        return _numFliesEaten;
    }

    public void SetNumFliesEaten(int value)
    {
        _numFliesEaten = value;
    }
}

}

Cool! I'm new to C# and I didn't know that you could use value as a parameter. I though is would cause an error :)

Thanks a ton! ~Alex

I can't make my code to work. Any suggestion?

namespace Treehouse.CodeChallenges { class Frog { private int _numFliesEaten;

    public int GetNumFliesEaten()
    {
        return _numFilesEaten;
    }

    public void SetNumFliesEaten(int x)
    {
        _numFliesEaten = x;
}

} }
