2Can you define `destroy`? – Yacoub Massad May 12 '16 at 16:51

3Also, how do you know that it didn't work? – Yacoub Massad May 12 '16 at 16:54

1@Erik Philips - Not sure why this was marked as a duplicate. This question doesn't ask about IDisposable. Furthermore, IDisposable does not destroy the object, it just allows cleaning up of resources, so the other question doesn't answer this question at all. – RJM May 12 '16 at 16:58

In addtion to setting your object as null , you should also remove it from other objects which refrences it as well if you class uses resources that needs to be freed up use IDisposable
public class Car: IDisposable
{
// free resources
public void Dispose()
{
}
}

There is nothing that OP mentioned in the question that requires to use `IDisposable` which is used usually for unmanged resources. – Yacoub Massad May 12 '16 at 16:53

Correct , but since this is a very general question , a more general answer seemed appropriate – Shachaf.Gortler May 12 '16 at 16:55

freeing Unmanaged resources if you class uses any , or also writing to a log – Shachaf.Gortler May 12 '16 at 17:07

set c = null; As long as there are no other references to it, the garbage collector will destroy it the next time it runs.

In what way doesn't it work? What behavior do you see after you set it to null that you're not expecting? – RJM May 12 '16 at 17:09

Yes, that code should work fine. The GC should destroy the object. Why do you think it's not working? – RJM May 12 '16 at 17:15

2@D4NieLDev - What did you try that made you think it didn't work? – Chris Dunaway May 12 '16 at 18:08
