You need to give more details than "this code doesn't work" if you expect an answer. What doesn't work? Is there an exception?

Let's start from the very elementary things:

Don't use System.Type.GetType("System.DateTime"); use typeof(System.DateTime).

How can you consider the first case maintainable? What if you mistype the type name? The compiler won't be able to check it up. Generally, using any immediate constants like your "System.DateTime" (except something like 0, 1 or null) is very bad for maintenance, even "" should not be used — use string.Empty instead.
