What is the Max size of Two Dimensional character array?

I have one two dimensional array:

char[,] DataFile;

When I create a object:

DataFile=new char[45000,6000]

It throws an out of memory exception.

What is the Max Size of object in .Net 3.5? What Is the Max Length of char array?

Well, it depends.

Obviously it'll matter how much physical memory (RAM) you've got installed and/or how large you set up virtual memory (swap).

In any case, in 32bit Windows maximum object size is 2GB. But there's another limit: The process image must have a contiguous block of memory of the required size.

Your array is about 514MB large. You should check for yourself if you have sufficient resources available.

There is no actual limit, it just depends on how much RAM your computer has, and how much contiguous memory the runtime can allocate.

Single objects still limited to 2 GB in size in CLR 4.0? already has quite a nice explanation of the limits in various circumstances.
