System.NewBee.Me == Bob

Bob, we can try to answer your questions but the best way to answer these questions, you need to find a book or document on Object oriented basics. That's the place where these terms are specified (namespace will not be there ;) but classes, objects, methods... will there). James already answered some of them. Here are few of them again, presented in different way. Namespace - is a way to orgazine a group of funcitonality in multiple classes, structures, and enumerations. So when you say a namespace, its a logical grouping of these times. So you can organize them under one umbrella. For example, System namespace is a logical grouping of classes, structures, and enumerations that defines system related functionality. Another example, say you are a company "ABC". You have classes for database, for UI, and for business logic. You can have namespaces ABC.Data, ABC.UI, ABC.BusinessLogic to put your database, UI, and business logic related functionality respectively. As James said, "Functions" are obselete in .NET. The term used is "Methods". So if somebody is talking about functions, they actually are talking about methods. Methods defined some code that does something. For example, Add method can add two numbers. NOTE: There are a few basic articles in "C# Language" section of this site. You may want to read them to learn these concepts in more details. Objects are instances of classes. For example, "Man" can be a class that defines what "a man" can have. For example, a man has legs, eyes, color, hair (these are properties), and man can walk, talk, work (these are methods). So Man class itself is a type or concepts, or a definition. When you say "Man is a class", means nothing but a definition. But when you say an "object", means something is there. For example, you and I are objects of Man class. We have those properties and methods. There is much more about all these. Too much to type. Again, look at Language section and read articles there about these concepts.

Hi Bob, well, this is kind of a general question on the layour of .Net apps, but I'll try to clear it up for you a bit... Namespaces.. Namespace are just what you said, a way of definining whats local to the code, and a way to organize you classes (using a tree-structure idea). There is a difference between Objects and Classes, but not a big one, and not one that you need to make a big distinction about at this point in your .Net experience. For the most part, you can use the term interchangeable. Keep in mind that everything in the .Net framework is derived from System.Object. Functions ... don't exist in this world, what you know as functions are called Methods. A class can have all of the following members... Methods Properties Enumerators Variables (and static members, AKA constants) Constructors (which are really just Methods called when a class is created) Events Structures ... I'm sure I'm leaving something out here, but those are the main types of members of a class. I hope that helps a bit. -James
