     this IEnumerable source)



Edit

Exceptions

Throws an ArgumentNullException if source is null.

Edit

Pseudo-code

If source is null, throw an ArgumentNullException.
Iterate the source sequence.
Type-cast the current element into the new type and return the result (pick up from here when the next element is requested).

Edit

Loop Count

This operator implements the standard deferred execution iterator pattern. This means, no looping will occur until the result is iterated over.
