The garbage collector will dispose it.

 

by: Zephyr__Posted on 2007-07-19 at 05:32:20ID: 19521251

Once the reference to the object goes out of scope the GC will free the memory that got used for it (whenever the GC does its next collect). If you stop using the object and the reference stays in scope for a long time, set the object reference to null, when the GC next time collects it'll free the object from memory as no references point to it...

e.g.
//use obj here...
obj = null; //finished with obj
//continue processing without obj

note you can also force a garbage collection like:
System.GC.Collect();

You could let your object implement IDisposable. There you can dispose all your resources that your class uses.
If you want to make sure that every object is disposed of as fast as possible: call the dispose function when you don't need it anymore.
It might take some time before the GC does the cleaning.
