Simple C# Question

I've coded my first program in C#. It's for finding the square root of a number. This is my code:

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

namespace ConsoleApplication1
{
class Program
{
static void Main(string[] args)
{
Console.WriteLine("What number?");
string dPre = Console.ReadLine();
decimal dDec = Convert.ToDecimal(dPre);
double d = Convert.ToDouble(dDec);
double sqrtLol = Math.Sqrt(d);
Console.WriteLine(sqrtLol);
Console.ReadLine();
}
static void

}
}


However it seems quite trivial to convert from string to decimal, and decimal to double. Isn't there an easier way?

Hi DarkLight

You can convert from string to double this by using the parse method


string dPre = Console.ReadLine();
double d = double.Parse( dPre );


Please note that a FormatException might be thrown if the user enters non-numerical characters....so, I would use a try catch block to handle the user input

Or use Double.TryParse.
