Can't figure out what's wrong (C#)

[OopsThatIsMine]

Hi, I'm trying to learn C# and I've tried making a single-input calculator (to calculate the odds of opening a knife in a CS:GO case when you open so many of them). 

I've got the errors "Cannot implicitly convert type 'string' to int'" (for line 10), "Cannot implicitly convert type 'double' to 'decimal'. An explicit conversion exists (are you missing a cast?)" (for line 11), and "Argument 1: cannot convert from 'decimal' to 'double'".

 

Does anyone know what's wrong and/or how to fix? Code is below. Thanks

 

using System;

 

namespace ConsoleApp1
{
    class Program
    {
        static void Main(string[] args)
        {
            Console.WriteLine("How many cases will you open?");
            int NoOfCase = Console.ReadLine();
            decimal RawOdds = 100 - 0.44;
            decimal OddsNoKnife = Math.Pow(RawOdds, NoOfCase);
            decimal OddsKnife = 100 - OddsNoKnife;

 

            Console.WriteLine("You have a " + OddsKnife + "% chance of getting a knife.");
        }
    }
}

Math.Pow does not take decimals, but doubles.

Thank you! I got it going

Also, in c# console.readline () returns a string and needs to be stored to a string value. Then you will need to change it to whatever data type you need using parse or tryparse. I always use tryparse to check for good input as int.tryparse () returns a Boolean value. So it's easy to say for example

Int noOfCases;

String noOfCaseString = console.Readline ();

While (!int.tryParse(noOfCaseString, out noOfCases)){

//reprompt for good input

}

//do stuff

 

(I'm on a phone so syntax might be off here or there)

On another note, if you absolutely needed the decimal data type, you could cast it to the appropriate data type and then cast it back, but this may have issues (there may be a loss in precision or something). But anyway, the code would look like:

decimal foobar = 0.0;
decimal A = 2.0;
decimal B = 2.0;
foobar = (decimal)Math.Pow((double)A,(double)B);
