OutOfMemoryException on declaration of Large Array

Question

I have to create a fairly large double array 12000ish x 55000ish. Unfortunately, I get an out of memory exception. I used to develop in Java and could change the memory sett

Answer 1

Providing that your total memory is sufficient, you can prevent Out of memory exceptions resulting from LOH fragmentation by creating a bunch of smaller arrays, and wrapping them in a single IList, or some other indexed interface.

Here is a link which describes it:

BigArray, getting around the 2GB array size limit
