Don't use the Array class. It is untyped and slow and the source of numerous questions on UA because of its untyped nature. If your data is of fixed size, then use a build-in array, which can be copied using System.Array.Copy(). If you need something of variable size, use one of the .NET generic collections like the List class (which has a Copy() method).

The Array class is never what anyone needs. ;) If someone really needed an untyped collection, then a built-in array or generic List using the Object type would work better, so Array is quite useless.
