what is ienumerable interface?

Answer

The IEnumerator interface provides iterative capability for
a collection that is internal to a class.
IEnumerator requires that you implement three methods:

The MoveNext method, which increments the collection
index by 1 and returns a bool that indicates whether the
end of the collection has been reached.

The Reset method, which resets the collection index to
its initial value of -1. This invalidates the enumerator.

The Current method, which returns the current object at
[position].

public bool MoveNext()
{
position++;
return (position < carlist.Length);
}

public void Reset()
{position = 0;}

public object Current
{
get { return carlist[position];}
}

IEnumerable interface
The IEnumerable interface provides support for the foreach
iteration. IEnumerable requires that you implement the
GetEnumerator method.

public IEnumerator GetEnumerator()
{
return (IEnumerator)this;
}
