You should only worry about having an explicit Dispose() method when you are dealing with unmanaged objects (e.g. file handles ala FileStream) inside your object.

Question
Creating a Dispose() funtion
I have an object that's used extensively inside my program and I would like to add a Dispose function. It also contains a few of my own object types and I'd like to give them dispose fuctions as well. But is there a way to tie it into a Delete method?
OR, do I need to find every place in my program where it's no longer used and explicitly call Dispose()?
I'm a former C++ programmer and never really got the cleanup process mailed down the way I could in C++, since in C++ the whole task was my responsibility. And I have never really been certain about what I am to do cleaning up in C#.
So please show me how to create a Delete() method or explain that I need to add in Dispose() funtion calls.
Thanks,
newbieweb

>> do I need to find every place in my program where it's no longer used and explicitly call Dispose()?
You are thinking like a C++ developer, you don't need to delete or dispose object instances. The garbage collector will know when an object is not needed (reference count=0).
Dispose() method is needed just in case your class/object contains a non-managed resource, like a GDI object, an SQL connection, or a file stream handler.
