Int multiply int a int b a b где ошибка

«The following code is not executing properly, try to figure out why.»

public class CustomMath {
public static int multiply(int a, string b) {
    return a * b;
}
}

Here’s my solution:

public class CustomMath 
{
    Int i = 1;

    public static int multiply(int a, int b) 
    {
    return a * b;
    }
}

I’m still plugging away at it started looking at operator overloading. Still catching the fail so I guess I am still not seeing it or failing to understand something about using operator overloading. Is the operator overloading my only issue or is my return syntax off?

using system;

public class CustomMath
{
    public static int operator *(int a, string b) 
    {
        return a * b;
    }
}

So I’m looking into binary operators, pretty sure my issue is that I am not expressing the int and string properly.

Your operator overload won’t work, because in order to overload the multiplication operator, at least one of the operands has to be of a user-defined type.

The thing is, you don’t need overloading at all. There are methods in the .NET framework designed specifically to «extract» an integer from a string, which is what you should do before multiplying anything. There are two easy ways of achieving this: int.Parse and int.TryParse. Just take a look at the MSDN documentation to figure out how they work and choose the best in your specific scenario.

And here is int.Parse in action:

string s = "5";
int i = int.Parse(s);
int j = i + 10 // At this point j = 15

Int multiply(int a, int b) { return (a*b); }
