Maximum number of elements in a 2D array

Tales Normando

Hi,

I'm writing a program where I need to generate a huge 2D table
(average 10000x5000) and I'm concerned about limitations in the number of
elements and memory space. Is it too big for .NET standards? Will it
generate an OutOfMemoryException? What other approachs are available to me?

Well, what's the size of each element? If they're just ints, then a
10000x5000 array will only take up about 200 megs - if you've got
enough memory in your computer, that should be fine.

It's hard to know what other approaches are available without knowing
what you need to do with the table.
