Consider this little program: using System; class MyClass { public int MyInt {get; set;} public MyClass(int myInt) { MyInt = myInt; } } class Test { static void Main() { MyClass mc = new MyClass(3); Console.WriteLine(mc.MyInt); // 3 Console.ReadKey(); } } Here MyClass is a blueprint for creating objects which have a single property of type int. MyClass has a constructor which initializes the MyInt property. The following expression creates a new instance (i.e. an object) of type MyClass whose property is equal to 3: new MyClass(3); This object is stored in an area of memory known as the heap. The above expression also returns a pointer to where this object is stored. However this isn't an ordinary pointer which never changes because the operation of the garbage collector (which cleans up objects which are no longer used) may cause the object to be relocated elsewhere in memory. It is instead called 'a reference' and if the object is relocated references are automatically updated to point to the same object as before. Finally this line causes the reference to be stored in the variable mc: MyClass mc = new MyClass(3); We can now use this variable to access the object's property and write it to the console using this line: Console.WriteLine(mc.MyInt);

Okay Object is the INSTANCE of Class and we acts a blue print of it. Then how the REFERENCE is related with it. If possible relate with Example.

A class is a blueprint for creating objects. An object is an instance of a class. A reference is a pointer to where an object is stored on the heap.
