using System;

namespace Exercise
{
    public abstract class Gun
    {
        public Gun(string name, int bullets)
        {
        }

        public string Name { get; set; }

        public int Bullets
        {
            get { return Bullets; }
            set 
            {
                if (value < 0)
                {
                    throw new ArgumentЕxception("Bullets cannot be below 0");
                }
                else
                {
                    Bullets = value;
                }
            }
        }
    }
}

This is the code that I am trying to run. I have checked and the framework is the same, which was an answer to a similar question. I am using VS code and have all the essential extensions downloaded. Do you have any idea what could be giving this error?

The type or namespace name 'ArgumentЕxception' could not be found (are you missing a using directive or an assembly reference?)

The problem is the "E" you're using. It's U+0415, or "Cyrillic capital letter ie"... instead of the ASCII capital E.

Just retype that E and all will be well.

When you have errors that don't quite make sense like this, if you suspect it may be an odd character issue (either an incorrect character like in this case, or unprintable characters) you might want to use a little utility I've got on a web page - my Unicode explorer. Just paste the text (in this case I copied "ArgumentЕxception") into the text box, and have a look at the characters it consists of.

You should also consider how you got into this state - if you can work out how you ended up with a non-ASCII character there, you might be able to avoid it in the future.

  • I see, I didn't know this tpe of error could cause this, but I have been pasting the code fro ArgumentException from Athanasios and not using my own. I also retyped it after, seeing your answer, but it still doesn't work. EDIT: THIS IS WRONG IT. THE CHARACTER WAS THE PROBLEM. I AM SO SORRY! – Martin Svilenski Oct 11 '20 at 08:33

    @MartinSvilenski: The code in your *question* has the problem, and has from the very first revision. I'm sure Athanasios just copy/pasted *your* code. Try just copy/pasting `ArgumentException` from this comment. If retyping it directly causes an issue, that suggests you might want to change your keyboard settings. – Jon Skeet Oct 11 '20 at 08:35
  • Edited my previous comment, you were right @JonSkeet – Martin Svilenski Oct 11 '20 at 08:35
