convert byte[] to short[] in C#

[eyalbi007]

Hi all,

I need to perfom simple-looking task in C#: Converting byte array to short array - meaning that if my byte array has 100 cells, my short array will have 50 cells.

If it was C/C++ it was simple, using pointers. However in C# I just can't do it - I've already tried using 'unsafe' block and memory pinning using GCHandle, with no success.

Another thing that bothers me in the solutions I found is that the conversion is done using memory copying, which is not necessary, since all the information is already there!

I'll be grateful for any solution!

Thanks,

Eyal.

Ok so you want say the first two bytes in the byte[] to be the first short in the short[] and so on and so on?
You're going to need to do some type casting I think.
Either that or use BitConverter and BinaryStream?

Hi,

Both solutions you suggested can do the trick, but only inside a for loop - and I need to cast the byte array to short array in one command, since it's very long array.

Can you use Array.Copy()?
You *might* be able to abuse an array of structs with custom marshalling assigned. But I have no idea how to do that.
