Cannot call public method [newbie]

jon 80

I am coding this utility to test raising of an exception, however, I have noted that Visual Studio 2010 IDE does not allow me to call the ArithmeticUtilityException.Divide() method. Why? I have also (desperately) tried to declare the class as static and the Divide() method as static, however, no joy either.

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;

namespace CustomException
{
class Program
{
static void Main(string[] args)
{
ArithmeticUtilityException utility = new ArithmeticUtilityException();
///Decimal myNumber = ArithmeticUtilityException.???
}
}

public class ArithmeticUtilityException : ApplicationException
{ 
    public ArithmeticUtilityException() : base() {}
    public ArithmeticUtilityException(string message) : base(message) {}
    public ArithmeticUtilityException(string message, Exception inner) : base(message, inner) {}
}

public static class ArithmethicUtility
{
    public decimal Divide(decimal number, decimal divisor)
    {
        try
        { return number / divisor; }
        catch (Exception err)
        {
            /\*  
             \* Create an instance of the specialized exception class, and, 
             \* place the original error in the InnerException property. 
             \*/
            ArithmeticUtilityException errNew = new ArithmeticUtilityException("Divide by zero", err);
            throw errNew;
        }
    }
}

}

:confused: NOTES 1. Related link Static Classes and Static Class Members (C# Programming Guide)
2. Personal note. ..\Training\CustomException.

Because you don't have one?

public class ArithmeticUtilityException : ApplicationException
{ 
    public ArithmeticUtilityException() : base() {}
    public ArithmeticUtilityException(string message) : base(message) {}
    public ArithmeticUtilityException(string message, Exception inner) : base(message, inner) {}
}

public static class ArithmethicUtility
{
    public decimal Divide(decimal number, decimal divisor)
    {
    ...
    }
}

Divide is a member of ArithmethicUtility, not ArithmeticUtilityException

You're welcome. :-D
