Question

As it is MyClass x = 120;, is it possible to create such a custom class?
If so, how can I do that?

Answer 1

It’s generally considered a bad idea to use implicit operators, as they are, after all, implicit and run behind your back. Debugging code littered with operator overloads is a nightmare. That said, with something like this:

public class Complex
{
    public int Real { get; set; }
    public int Imaginary { get; set; }

    public static implicit operator Complex(int value)
    {
        Complex x = new Complex();
        x.Real = value;
        return x;
    }
}

you could use:

Complex complex = 10;

or you could ever overload the + operator

public static Complex operator +(Complex cmp, int value)
{
  Complex x = new Complex();
  x.Real = cmp.Real + value;
  x.Imaginary = cmp.Imaginary;
  return x;
 }

and use code like

complex +=5;
