How would you create multiple index arrays and dynamic arrays in DarkGDK?

Not sure about multiple index arrays, maybe maps. But indexes are positional things and I guess what you really would need would be a class that includes the data and whatever values you're indexing with. I would think they wouldn't be time efficient though

Dynanmic arrays are usually handled by vectors. This is all under C++. C# might have some collection classes that do a better job.

Single dimensional arrays, dynamic or not, are probably best handled by the vector class.

Multidimensional arrays can be handled by writing a wrapper around vector, and this is what I've done in the past - it's a pain growing the individual vectors that make it up when you expand a dimension though.

Recently, I've been looking at the Boost Multi-Array class - this allows any number of dimensions, and allows you to resize them dynamically. The downside (slight though it is) is a little more complexity - the Introductory page tells you most of what you'll need to know. It's a header-only library, so once you '#include' it, you're good to go.
