C#: convert generic pointer to array

Question

I want to convert a byte* to a byte[], but I also want to have a reusable function to do this:

public unsafe static T[] Create

        

Answer 1

I have no idea whatsoever if the following would work, but it might (at least it compiles :):

public unsafe static T[] Create(void* ptr, int length) where T : struct
{
    T[] array = new T[length];

    for (int i = 0; i < length; i++)
    {
        array[i] = (T)Marshal.PtrToStructure(new IntPtr(ptr), typeof(T));
    }

    return array;
}

The key is to use Marshal.PtrToStructure to convert to the correct type.
