How to clear all controls on a custom sheet

Well, I probably have close to 100 controls that I need to clear and was hoping to not have to list them each out. I have done some coding before (probably about 10 years ago now), but just am not that familiar yet with C#. If someone has the basics of how I would try to get the controls from the page, I can probably work through the remainder of the code to make them all cleared.
