This is something that I have never fully grasped in .NET as to the correct application of the .dispose() method.
Say I have something like
Public Class someClass()
sub someMethod
' do some stuff tying up resources
end sub
End Class
public class mainApp
dim _class as new SomeClass
_class.someMethod()
End Class
In all cases is it good practice to implement a dispose method, and if so what should go in there?
If it is not the case that every class should have dispose method (which my gut feeling says the shouldn't) what classes should? I have always thought anything which may tie up a resource (i.e. connection, datareader etc) should have a .dispose() which would unallocate these resources.
Also how would you enforce a calling into calling the .dispose() method?

The Dispose() method The Dispose method performs all object cleanup, so the garbage collector no longer needs to call the objects' Object. Finalize override. Therefore, the call to the SuppressFinalize method prevents the garbage collector from running the finalizer. If the type has no finalizer, the call to GC.
Dispose is a method triggered whenever the created object from the stateful widget is removed permanently from the widget tree. It is generally overridden and called only when the state object is destroyed. Dispose releases the memory allocated to the existing variables of the state.
Dispose() vs. Net documentation for the OleDbCommand, Close() closes the connection and returns it to the connection pool, and Dispose() closes the connection and REMOVES it from the connection pool.
It only occurs when there are objects in the Finalization Queue. It only occurs when a garbage collection occurs for Gen2 (which is approx 1 in every 100 collections for a well-written . NET app).
It's a fairly long answer to cover everything fully, so hopefully nobody will mind if I link to a blog post which should hopefully answer everything.
