Var and object in C#

Hello Vulpes,
                 you are right.
                we can put an object to var and also a var to object.
                it tried both 
                as
                

{

static void Main(string[] args)//var a = "10";

//object b;

//b = a;

//var c = b;

//Console.WriteLine(c);

//Console.ReadKey();

O

var b = a;

object c = b;

Console.WriteLine(c);

Console.ReadKey();

}

both gives same result with out an error

bject a="10";

Var is a data type that is predefine.
but object is a root data type
we can put a "var" type variable in object type
it supports implicit casting in that case
as

var a=10;
object b=a;
 
there is no need to cast

but if we retrive this value
we have to cast with var type

as

var c=(var)b;
