Need help with accepting decimals as input in C#

Question

I have written a program in C# that runs the Pythagorean Theorem. I would love some help on allowing the program to accept decimal points from the user input. This is what I

Answer 1

I would recommend using Decimal.TryParse. This pattern is very safe since it traps the exceptions and returns a boolean to determine the success of the parse operation.

Answer 2

static decimal RequestDecimal(string message)
{
    decimal result;
    do 
    {
         Console.WriteLine(message);
    }
    while (!decimal.TryParse(Console.ReadLine(), out result));
    return result;
}

Answer 3

Math.Pow doesnt take in decimal. There is already another question on SO about Math.Pow and decimal. Use double.

static void Main(string[] args)
        {
            double sideA = 0;
            double sideB = 0; 
            double sideC = 0; 
            Console.Write("Enter an integer for Side A ");
            sideA = Convert.ToDouble(Console.ReadLine()); 
            Console.Write("Enter an integer for Side B ");
            sideB = Convert.ToDouble(Console.ReadLine()); 
            sideC = Math.Pow((sideA * sideA + sideB * sideB), .5); 
            Console.Write("Side C has this length..."); 
            Console.WriteLine(sideC); 
            Console.ReadLine();
        }
