Convert string to int in C# please

Question

I'm new to C# and programming.

I tried everything but I'm too stupid to convert the string "password" to an int. This is my failing code:

namespace idk
{
    public static class Program
    {
        public static void Main()
        {
            var password = Console.ReadLine();

            int gues = 0;
          
            do
            {
                gues = gues + 1;
            } while (gues == password);
            
            Console.WriteLine("done");
        }
    }
}

What value do you want to convert "password" to?? Do you want to **(1)** determine the **length** of the string? **(2)** Do you want to calculate some kind of a checksum over the string entered? **(3)** something else entirely?? You're not being very clear about your goals.... a string is multiple characters - what `int` do you want to convert these to?? — marc_s, Apr 22 '22 at 14:13
what **is** `password`? What do your type into you app? I can't imagine `"Hello World"` to be convertible to an `int`, so you seem to have some hidden knowledge about your data that we do not have. — MakePeaceGreatAgain, Apr 22 '22 at 14:18

System.Convert.ToInt32(password)

MS Reference

You can then compare gues (int) with password (int)

Use TryParse(String, Int32) Converts the string representation of a number to its 32-bit signed integer equivalent. A return value indicates whether the conversion succeeded. Also be aware that normally passwords should be stored in SecureString type avoiding conversion to String.

Best thing is only to allow numbers to begin with if you want numbers anyway. See following answer for some reference how to do it:
