Difference between IEnumerator and IEnumerable Interface in C#
IEnumerable and IEnumerator both are interfaces in C#.
IEnumerable is an interface defining a single method GetEnumerator() that returns an IEnumerator interface.
This works for readonly access to a collection that implements that IEnumerable can be used with a foreach statement.
IEnumerator has two methods MoveNext and Reset. It also has a property called Current.
The following shows the implementation of IEnumerable and IEnumerator.
Example
class Demo : IEnumerable, IEnumerator {
// IEnumerable method GetEnumerator()
IEnumerator IEnumerable.GetEnumerator() {
throw new NotImplementedException();
}
public object Current {
get { throw new NotImplementedException(); }
}
// IEnumertor method
public bool MoveNext() {
throw new NotImplementedException();
}
// IEnumertor method
public void Reset() {
throw new NotImplementedException();
}
}Above you can see the two methods of IEnumerator.
// IEnumertor method
public bool MoveNext() {
throw new NotImplementedException();
}
// IEnumertor method
public void Reset() {
throw new NotImplementedException();
}
