I'm trying to create a large array, but every time I got a memory exception.

I'm just wondering is there a way to use up all the memory of the computer ?

I've tried to use void* PyObject_Malloc(size_t n) on the documentation, but I'm not sure what's the correct way of using this method.

For example, when I try:

array = [None]*999999999

it gives me System.OutOfMemoryException

I'm expecting to use all the memory of my computer. The python process uses around 1.5 GB memory and throws the exception, while my computer has 8 GB of memory

I'm using IronPython, so I can' use libs like numpy.

python ironpython

  That is not an array, that is a list. Now, I'm not sure exactly how IronPython implements list objects, but likekly, it requires some sort of array of PyObject's (whatever they are called in the IronPython implementation). Which likely requires at the minimum an underlying buffer of machine-word pointers, 8 bytes per object, so 999999999*8*1e-9 ==7.9999 gigabytes. You are simply out of memory. Note, None is likely a singleton, but if you are going to put any other objects in there, they will require even more memory.
