Getter & Setter version Difference

What is the difference from these 2 codes?

version 1:

public int Armor {get;set;}

version 2:

int armor;
public int Armor {
		get{ return armor; }
		set{ armor = value; }
	}

I had both tested and they do exactly the same thing. Could I continue using version 1 without any problems, since its less code?

If I set the armor to 4, both versions will have a result of 4.

Yes, the first one is a shorthand for the second one. The only difference is that the first one will create a private variable to use for this property and you can’t access it, with the second method you can (some times it’s usefull to access the variable without using the property).
