Can you use List> to get around the 2gb object limit?

Question

I\'m running up against the 2gb object limit in c# (this applies even in 64 bit for some annoying reason) with a large collection of structs (est. size of 4.2 gig in total).

Answer 1

In versions of .NET prior to 4.5, the maximum object size is 2GB. From 4.5 onwards you can allocate larger objects if gcAllowVeryLargeObjects is enabled. Note that the limit for string is not affected, but "arrays" should cover "lists" too, since lists are backed by arrays.
