Storing children class in Parent Class

[mirhagk]

Is this possible/does these produce off side-effects

code:

abstract class ConditionPoll : TriggerCondition {       public class HealthCheck : ConditionPoll      {      } }

I'm using C#, and this just seems like the cleanest way to organize my code. Putting all the children inside the abstract parent class makes it much simpler to organize.
