c# attempting to overload a cast from short to bool

I am attempting to overload a cast to short from a boolean. (true is 1 false is 0)

not quite sure how to go about it.
here was my attempt.

here is the fiddle
https://dotnetfiddle.net/STWWfy

using System;
					
public class Program
{
	public static void Main()
	{
		MyClass myObject = new MyClass();
		myObject.x = (short)false;
	}
}

public class MyClass
	{
	  public short x {get; set;}
    }

public static implicit operator short(bool v)
{
    return (short)(v ? 1 : 0);
}

There are built-in methods to do this, see the Convert class:

var x = Convert.ToInt16(true);   // x == 1
var y = Convert.ToInt16(false);  // y == 0

As others have said, you can't write your own conversions, only for types that you define.
