在C＃中创建用于填充下拉列表，网格等的类

Please keep in mind that I'm new to C# and OOP so I apologize in advance if this seems like an easy question to some. I'm going back through my code and looking for ways to objectify repetitive code and create a class for it so that I can simply reuse the class. That being said, I'm not looking to learn NHibernate or any other ORM just yet. I'm not even looking to learn LINQ. I want to hack through this to learn.Please keep in mind that I'm new to C# and OOP
