how to copy multi-dim Array into IntPtr (or byte[])?

an external API that we're using is giving me back video data in a
multi-dimensional Array (not byte[], just System.Array). so, for an HD
quality video, the data is organized as [3][1280][720] of bytes. i know
this rather weird, but it's what i have to work with...

i've been reading thru Array.Copy and other related methods, but nothing
seems appropriate or efficient.

i'd rather not have to copy into a big byte[] array and them Marshal.Copy
that into an allocated IntPtr, but if that's what it takes, i'll have to do
it.

my biggest problem is i don't even know how to flatten the multi-dim array
into a byte[] array. optimally, i'd like to do it into one step into the
allocated IntPtr from the multi-dim array.

thanks for any help,
Kirk

Hi, I need to do a raw copy of a byte array to an Int16 array. For e.g., I have an byte array which has length 100, and I need to copy this to an Int16 array that has length 50. So 2 elements in the byte array gets copied to 1 element in the Int16 array. In VB6, this was easily done using CopyMemory. I need something in .NET that works as fast as CopyMemory. I

I am new to vb. net, and would like to implement a method I used in vb6. I need to write binary data to the hard drive ASAP.

Hello folks, I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>".

Here is my compilation command: g++-12 -std=c++20 -Wnarrowing bit_field.cpp Here is the code in...

In Windows 11 and 10, there is no way to turn off the Windows Update option using the Control Panel or Settings app; it automatically checks for updates and installs any it finds, whether you like it or not. For most users, this new feature is actually very convenient. If you want to control the update process,...
