| I'm porting Delphi code to C#.
| In a Delphi class, you cleanup a class instance from the destructor. But 
in
| C#, there is no destructor.
| So where do I put cleanup code (such as closing database connection) ?
| Should I put the cleanup code in Finalize() ?
| Can I explicitely call Finalize() when I'm done with an object ?
| I don't want the cleanup code to be called when the object instance is
| garbage collected. I want it to be executed when I'm done with the object
| instance.
|
| Maybe a better design is to create my Cleanup() method and call it from
| where I used to call Delphi's destructor ?

Unless you are using classes that implement IDisposable, those which hold 
Windows resources like file or UI handles, etc, you don't need to do any 
cleanup. In fact doing cleanup really fouls up the garbage collection and 
can slow your program due to memory fragmentation.

If your code doesn't use Windows resources and you think deterministic 
cleanup is important, then you need to thnk about redesigning to work with, 
not against the GC.
