How do I force release memory occupied by MemoryStream?

Question

I have the following code:

const int bufferSize = 1024 * 1024;
var buffer = new byte[bufferSize];
for (int i = 0; i < 10; i++)
{
    const int writesCount = 4

Looks like you're allocating too much than your system can handle. Your code runs fine on my machine, but if I change it like this :

const int bufferSize = 1024 * 1024 * 2;

I get the same error as you.

But if I change the target processor to x64, then the code runs, which seems logical as you can address lot more memory.
