I am currently using VS 2008 64 bit edition, 3.5 framework with SP1. However, it appears that the collection classes like List have a limit of 2^31 (or max value of an int) elements that it can contain.
Does anyone know if there are any true 64 bit collections that can handle more than 2^31 elements within a container? If not for VS 2008, then what about VS 2010? Any 3rd party collections out there that do this?
I am pretty sure there are no builtin collections that can handle more than
Int32.MaxValueentries. The reason is because the .NET Framework still has ~2GB limit for objects even for the 64-bit version.Int32.MaxValueentries of one byte bumps up against this limit. I believe Mono’s memory limit is larger, but I cannot definitely confirm that.You can work around this limitation using the
BigArrayimplemenation from here.
