Prior to .NET 2.0, the only way you could create your own collection which could be traversed using the 'foreach' construct was by having you class implementing the IEnumerable and IEnumerator Interfaces. However since .NET 2.0 we have a new operator called 'yield'. This allows your class to be iterated by its consumer but without the need to implement the above-mentioned interfaces.
