Shallow copy is a bit-wise copy of an object. A new object is created that has an exact copy of the values in the original object. If any of the fields of the object are references to other objects, just the reference addresses are copied i.e., only the memory address is copied. deep copy copies all fields, and makes copies of dynamically allocated memory pointed to by the fields. A deep copy occurs when an object is copied along with the objects to which it refers.
A shallow copy of a collection copies only the elements of the collection, whether they are reference types or value types, but it does not copy the objects that the references refer to. The references in the new collection point to the same objects that the references in the original collection point to. In contrast, a deep copy of a collection copies the elements and everything directly or indirectly referenced by the elements. ArrayList.Clone Method >> Creates a shallow copy of the ArrayList.
