Question about properties block

[perlnewbie9292]

Hello I am new to C# and I am going through some examples.

I ran across this example for passing data between forms and I am not quite sure with the extra stuff after the return (memberVariable)

Specifically the == 0 ? 0 : totalHoursDecimal / numOfChargeInteger; part? Is there another way to write this same line of code?

Thanks for the help in advanced.

        public decimal avgCostDecimal
        {
            get
            {
                return numOfChargeInteger == 0 ? 0 : totalHoursDecimal / numOfChargeInteger;
            }
        }

it's syntax sugar for

if(numberOfChargeInteger == 0)
{
   return 0;
}
return totalHoursDecimal / numberOfChargeInteger;

The ?: is called the conditional operator - here's a snippet from msdn:

The conditional operator (? returns one of two values depending on the value of a Boolean expression. The conditional operator is of the form

    condition ? first_expression : second_expression;

Hope it helps.
