Is it possible to have a “var” as a Global variable [closed]

Answer 1

No, because var is not a type itself, it merely takes on the form of whatever expression is on the righthand side of the assignment:

var num = 1;

is the same as:

int num = 1;

when declaring variables that are scoped outside of a method, you need to use the full type designator:

public static int num = 1;

or

public static int Num {get;set;}

etc
