what is the difference between passing a value object by reference and a reference object by value?..

I am sorry ...above is not correct....actually to pass
reference type as value we need to use clonable/ copy
constructor ...otherwise in C# it is not possible to pass
object as value

Answer / ashish diwakar

..........For above example..............

Well I skip to add .ToString in my above answer.

We can not pass Reference type objects directly to a method.
So to pass value of sb variable we need to use following
code:

Display(sb.ToString());

..........For above example..............

Answer / ashish diwakar

Value Objects are the objects that contain the data as
objects such int, string, etc...
Reference Objects are the objects that contain the data as
reference such as StringBuilder,etc...

When a Value object is passed as reference the reference of
the object is passed to the method (which means that any
change made to variable will be reflected on the original
variable).
But when a Reference Object is passed by value Like :
StringBuilder sb =new StringBuilder();

sb.Append("hello");

Display(sb);

any change made on sb inside Display function will not
change value of sb.

Answer / c

When you pass object by reference to any method, you are
passing reference (base pointer) to method. Any changes
done on this object will get reflected in object in caller.

When you pass any object by value, you are passing copy of
the object and not the reference.
