Explain Enumarator and Enumaration

Question

Hello guys...... I am confuse in what is the difference between Enumerator and Enumerable?

Sumit Joshi · Answer

Hi Sachin Enumerator:It is an output of method hat makes enumeration possible. Enumerable: It is a type that can be Enumerated using an Enumerator Some more Light on it Every type that implements the IEnumerable interface should implement a method GetEnumerator which returns a type that implements the IEnumerator interface. Then having an enumerator you can use the foreach statement which in its essence implements the iterator pattern to traverse the elements of a collection of your custom type. If Helpful mark as Correct Answer

Sujeet Suman · Answer

IEnumerable is an interface that defines one method GetEnumerator which returns an IEnumerator interface this in turn allows readonly access to a collection. A collection that implements IEnumerable can be used with a foreach statement.
