Difference between class and instance variables. Now, it should be clear what the difference between instance and class variables is. Class variables only have one copy that is shared by all the different objects of a class, whereas every object has itâs own personal copy of an instance variable. So, instance variables across different objects can have different values whereas class variables across different objects can have only one value.
Because classes are reference types, a variable of a class object holds a reference to the address of the object on the managed heap. If a second object of the same type is assigned to the first object, then both variables refer to the object at that address.n the following example, Person is the type and person1 and person 2 are instances, or objects, of that type. C#. Copy. Because structs are value types, a variable of a struct object holds a copy of the entire object.
