Question regarding creating controls on forms.

Question

I am new to C#. I have a couple of questions. It appears that most sample code that I find on the Internet or in books create controls on Winforms dynamically. This includes setting the Text property and setting the location of the control on the form dynamically. Is this the norm and is there an advantage to this? Also, in VB I usually have a Module with a ton misc. routines that I use that may not fit in a certain module or class. Is the propery way to replicate using modules(in VB) using classes in C#?
