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

As of C# 7.3 this is possible as follows:

public unsafe static T[] Create(T* ptr, int length) where T: unmanaged
{
    T[] array = new T[length];
    for (int i = 0; i < length; i++)
        array[i] = ptr[i];
    return array;
}
