Trouble Creating forms dynamically

I am trying to build a form dynamically.  I have a class that I've created to do the dirty work.  The class accepts a form and attempts to recreate it dynamically.  The class walks through the controls and attempts to recreate them using the System.Reflection namespace.  Everything works great accept for the properties with complex types.  For example, the Alignment property is System.Windows.Forms.TabAlignment enumeration type.  How do I convert the value "Top" to the System.Windows.Forms.TabAlignment.Top enumerated value?

(System.Windows.Forms.TabAlignment) enum.Parse(typeof(System.Windows.Forms.TabAlignment), "Top")

But if you use reflection, you might need to get the type first right? Then it might be

Type t = Type.GetType("System.Windows.Forms.TabAlignment");
object o =  enum.Parse(t, "Top")  

then you can use reflection setvalue to set value to System.Windows.Forms.TabAlignment.Top

ok - now how do I execute the same statement but with following comments:

(System.Windows.Forms.TabAlignment) - this value is retrieved from a configuration file and stored in a string.  How do I create the same typecast using a string?

typeof(System.Windows.Forms.TabAlignment) - again, this value is stored in a string.  How do I use typeof with a string variable?

Thanks for your help so far!!!

i can't get it to compile - it fails on the enum.Parse.  What am I missing?

And it should be

Type t = typeof(System.Windows.Forms.Control).Assembly.GetType("System.Windows.Forms.TabAlignment");
object x = Enum.Parse(t,"Top");

object x will contain System.Windows.Forms.TabAlignment.Top
