Question

I’ve been looking through the Marshal class, but I can’t seem to find a method that allows me to copy from an unmanaged array (IntPtr) to another unmanaged array (IntPtr).

Is this possible using .NET?

You can also DllImport RtlMoveMemory to get the job done:

[DllImport("Kernel32.dll", EntryPoint="RtlMoveMemory", SetLastError=false)]
static extern void MoveMemory(IntPtr dest, IntPtr src, int size);

This will also require FullTrust, however, but as you are working with unmanaged code, I’d expect you already have it.
