Comparing IEnumerable and IEnumerator
The IEnumerable and IEnumerator interfaces can both be used for iteration but in different ways. Let's understand each in brief.
An object of the IEnumerable type will know how to traverse the collection that it holds, regardless of what its internal structure is like. There is one method that makes up an enumerable: GetEnumerator(). It returns as an instance of a class that implements the IEnumerable interface. Iteration is normally carried out using a foreach loop. Iterations of an enumerable are carried out using a foreach loop. However, an enumerable does not remember its location when iterating.
Objects of the Ienumerator type declare two methods: MoveNext() and Reset(). There is one property called Current that gets the current item in the list that's being enumerated. The MoveNext() method moves to the next record in a collection and returns a Boolean value indicating the end of the collection. Reset() will reset the position...
