Gerrit:
I got a good laugh out of this one :)
You can change ASP.NET to use more memory in the processModel...it's set to
60% by default...you can up it..but you'll run into a win32 2gig process
limit (60% of 2.5 is 1.5..so you might be able to get 1.8..but I wouldn't
push it more than that).
Seriously though, some suggestions:
1 - Atleast consider a generic List<Byte which can have it's size
allocated dynamically..so if you only need 100 mb's, you don't need to
allocate any more.
2 - Is it at all possible to process these images in smaller chunks? or do
you need to do everything all at once?
Also, I THINK depending on where this is defined, the allocation might
happen on the stack instead of the heap...which is much smaller. I'm just
guessing here. I'm I'm right, you'd certainly run up against a limit at 420
megs. The solution might be to define test as an object field...which will
then make it get allocated on the heap..

Thank you for your advice!
But I need to use this big array. In my application I want to generate
thumbs and previews from uploaded images and I do not expect that these
images are greater than 100MB in normal case. But in some cases these
images can be about 1 GB. (Perhaps every 6 Month...)
My PC has 2,5 GB of RAM and it's although not able to generate this
array. What do I have to do to make this possible. Is there any system
property in the machine.conig or something else I could do?
Thanks in advance

instance, but what happens if even two users work the code that requires
a
400 MB byte array allocated. I'm not exactly sure if that's a feasible
array
size for a server environment which could be why it's not letting you do
it.
Hope this helps,

Hi all,
I'm getting an OutOfMemoryException when I initialize a byte array in
C# like this:
Byte[] test = new Byte[420000000];
I'm using ASP.NET 2.0. In ASP.Net 1.1 it works fine. So what am I doing
wrong?
What is the maximum length of a byte array?
Can somebody help me? Thanks in advance!
