Need C# code that will eat up system memory.

Question

I need the opposite of good, optimized code. For testing purposes I need a simple program to eat up RAM. Preferably not all memory so that the OS is non-functional, but more like something that would simulate a memory leak, using up a lot of memory and slowing down the OS, gradually, overtime.

Specifically, can anyone provide code spinets or links to tutorials I can use?

I saw this code as a suggestion on another post:

for (object[] o = null;; o = new[] { o }); 

But it is not quite what I am looking for as per the description above.

Please help.

Answer 1

Use

Marshal.AllocHGlobal(numbytes) 

You can attach this to a timer. And just dont release the memory (dont call FreeHGlobal). Thats the most straighforward, controllable and predictable way to consume memory.

Marhsal.AllocHGlobal
