C＃对象层次结构设计

Question

I have created a series of related objects in my C# application...

Object A contains a list made up of Object B's, Object B's contain a list of Object C's.

Object A is currently writing information to a log file, depending on Object A's instance name (eg there are three Object A instances in my application "Server 1", "Server 2", "Server 3"). So each instance of Object A writes to it's own log file.

How do I get Object B to write information to the "Server 1" log file if it is in a collection belonging to "Server 1"?

As far as I know, Object B does not know it is part of a collection of Object B's belonging to Object A. Object B knows nothing about Object A and hence can't get Object A's name to write to the same log file for the particular instance of Object B.

Have I designed this poorly? Is there a method or way for Object B to check if it is part of some collection at runtime and get information from Object A?
