>We have C and Assembly language to thank for that. Arrays/indexes are based on pointers moving through a list typically and pointer offsets always start at 0. It's convention and it makes goods sense since that's how computers work.

It would destroy the whole continuity and familiarity with the syntax.

Additionally in C# it's not that frequent that you use for x loops - most operations in .NET involve foreach() iteration with enumerators which are much cleaner syntactly and removing the need to know anything about array indexes at all.

Thanks, yes, I have a lot of For/Each, but also have the For/Next support at various locations. As you said, the first one doesn't require a pointer while the next one does.
