What is the difference between IEnumerable and IEnumerator? ASP.Net

IEnumerable is an interface for all non-generic collections that can be enumerated. IEnumerable contains a single method, GetEnumerator, which returns an IEnumerator.

Syntax:

public interface IEnumerable
{
IEnumerator GetEnumerator();
}

IEnumerator provides the ability to iterate through the collection by exposing a Current property and MoveNext and Reset methods. Enumerators can be used to read the data in the collection, but they cannot be used to modify the underlying collection.

Syntax:

public interface IEnumerator
{
object Current { get; }
bool MoveNext();
void Reset();
}
