C# C# Objects Inheritance Custom Exceptions

Can't figure out what I'm doing wrong when creating exception...

I think I'm doing something wrong when creating the constructor for the TooBigException class.

It keeps telling me this message: "Did you create a constructor for TooBigException that takes a string parameter?"

TooBigException.cs
namespace Treehouse.CodeChallenges
{
    class TooBigException : System.Exception
    {
        public TooBigException(String message) : base(message)
        {

        }
    }
}

:point_right: You want to take a string (lowercase) parameter, not a String (uppercase S).

They are both valid types, but they are not the same thing.

Wow! Thank you very much! Now I'll be aware of it.

Aaahh the little details! It's awesome!

I have investigated a little bit and found that string is an alias in C# for System.String presuming that they are the same type.

Do you know where it is recommended to use each one? Is it better to use a particular one for consistency with your code?
