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.

Correct , but since this is a very general question , a more general answer seemed appropriate

what should I put in the method?
Shachaf.Gortler
freeing Unmanaged resources if you class uses any , or also writing to a log

What do you mean by saying unmanaged resources?

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?

this is my code:
Car c = new Car(); c = null; Console.ReadLine();RJM
Yes, that code should work fine. The GC should destroy the object. Why do you think it's not working?
