Compiler error

I'm not certain exactly were I went wrong: Frog.cs(7,30): error CS0102: The type Treehouse.CodeChallenges.Frog' already contains a definition for_numFliesEaten' Frog.cs(5,21): (Location of the symbol related to previous error) Frog.cs(12,10): error CS1525: Unexpected symbol }', expecting;' Compilation failed: 2 error(s), 0 warnings

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

        public NumFliesEaten _numFliesEaten
        {
          get
          {
              return _numFliesEaten
          }

          set
          {
              _numFliesEaten = value;
          }


        }
    }
}

Hi Tojo,

The syntax of a public property in C# is : public [type of property] [Property name] In your case is should be : public int NumFliesEaten.

So your code should look like so

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

        public int NumFliesEaten
        {
          get
          {
              return _numFliesEaten
          }
          set
          {
              _numFliesEaten = value;
          }
        }
    }
}

If not for challenge, you could also use auto-implemented properties in C# like so. It's very clean and concise :)

namespace Treehouse.CodeChallenges
{
    public class Frog
    {
        public int NumFliesEaten { get; set; }
    }
}

All the best and happy coding :)

To solve Frog.cs(7,30): error CS0102: The type Treehouse.CodeChallenges.Frog' already contains a definition for_numFliesEaten', you have to rename the property.

You already initialized _numFliesEaten as an int field. You can't also name a property _numFliesEaten too because there's already something that's called that.

So 

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

        public int NumFliesEaten
        {
          get
          {
              return _numFliesEaten;
          }

          set
          {
              _numFliesEaten = value;
          }


        }
    }
}

For the other error, you just forgot to add a semicolon to the end of your getter.

Hope this helps!
