The case of multi-dimensional arrays with dimension 1

[kaimikael]

There is a special case in that if one calls Array.CreateInstance(typeof(T), new int[]{num1}, new int[]{num2}) (where num1 and num2 are arbitrary integers ≠ 0), the resulting array cannot be cast to T[]. It is a multi-dimensional array of rank 1, not a one-dimensional array. It can only be used as a System.Array.
It would be nice if this was mentioned in the documentation, as one occasionally runs into that special case.

I guess the first paragraph in my note above could be used and pasted right in? I’m a bit shy about mucking about in the docs on my own.
