This method is equivalent to the standard C / C ++ function memmove, not memcpy.

It is true that copying part of an array is not easy, using CopyTowithout parameters to control the range. However, you can use ArraySegmentor array.Skip(offset).Take(length)to achieve it.
And there are no problems in my test.
