C# If statement help

Recommended Posts

Wombat

I've been all over the web looking for an answer but have found nothing yet. So I'm turning to the one code community I trust for help...

Please tell me why this produces an error after the ')' in the if statement if (MathJob=*)

using System;


class Program
{
    static void Main()
        {
            Console.WriteLine("Please type a number: ");

            int Digit1 = int.Parse(Console.ReadLine());

            Console.WriteLine("Please enter a math function to use (+, -, *, /) : ");

            char MathJob = char.Parse(Console.ReadLine());
            
            Console.WriteLine("Please type another number: ");

            int Digit2 = int.Parse(Console.ReadLine());
            
            int Result = 0;
            
            if (MathJob=*)
            {
                Result = Digit1 * Digit2;
            }

            Console.WriteLine(Digit1 + MathJob + Digit2 + " = " + Result);

            Console.WriteLine("Press any key to continue...");
            Console.ReadKey(true);

        }
}

Just look at us.

Equality comparisons use "==" not "=", don't they?


If I posted any code, assume that code was written using the latest release version unless stated otherwise. Also, if it doesn't work on XP I can't help with that because I don't have access to XP, and I'm not going to.

I thought so as well but (MathJob==*) returns the same error

Invalid expression term ')'       Line 22
) expected                        Line 22

 if (MathJob == '*')

Also, aren't strings supposed to be inside quotes?

This was the proper syntax. Thank you both for the input :)
