Using a method or class to call a form control from a class file.

Helo my ASP.NET friends. I have a form containing several controls. I also added a Class by going to Add New Item and selecting Class. My question is how can I create method in my class that allows me to access all of the form controls?. I do not want to create individual methods for each control, just one, maybe a Class object and then use it to call the form controls. Thanks.
