int i=123; //i is value type object o=i; //o is reference type, so when you assign
a value type to a reference type the frameowrk creates a boxed object on the heap with
the same value, at this point there is the value i on stack and the reference type
object o on the heap i=456; // you are manipulating the value on the stack the
object o on the heap does not get affected. Console.WriteLine(o.ToString()); //
Since o still has the value 123 that is what gets printed. When the above code is
executed it is printing as 123, When i change into like below object i=new
string(new char[]{'1'}); //i is reference type, i------->['1'] object o=i; //o is
reference type, so basically a pointer to the actual object on the heap gets assigned
to o. Now o and i refer to the same object. o ------->['1']<-------- i i="456";
//Now you are assigning a new object to the reference i i -------->['456]
o--------->['1'] Console.WriteLine(o.ToString()); //Since o still points to the old
object it will print 1 Then also it is printing 1. When I assign a ref type it is
going to assign the reference only. Then how this is showing the value as 1 it has to
show as 456 only right. One more question all objects are derived from System.object
class so that all objects will have the ToString() method. When declare a interger
variable as int i=1234; Then When I write i.ToString(); Its converting into string
>From where this ToString() method came from coz i is a value type. System.Object is
the base class of System.ValueType
