Reflection questionsif I have two classes, ClassA and ClassB, and ClassA has a member of type ClassB, is it possible from within ClassB to find out that the current instance is a member of ClassA? Example: class ClassA { private ClassB _myClassB = new ClassB(); } class ClassB { public void FindOwner() { // is there some way to find out, that this // instance is a member of an instance of // ClassA, e.g. using reflection? } } Thanks, Martin Martin Bischoff <nitramb4@newsgroup.nospam> wrote:

I agree with Barry, that we can only see a parent has a certain child. But we cannot check which parent a child belongs to in a very simple method. As Barry mentioned, only with a brute-force search, can we get the parent of certain child.

need any help. Kevin Yu Microsoft Online Community Support ================================================== (This posting is provided "AS IS", with no warranties, and confers no rights.) Errrr.... forgive me if this is a dumb question, but if an object must know
who created it, why not force anything creating that object to supply a this, i.e. : class ClassA { private ClassB _myClassB; public ClassA() { _myClassB = new ClassB(this); } } class ClassB { private object parent; public ClassB(object daddy) { this.parent = daddy } public void FindOwner() { // Get the info from this.parent } } HTH, Adam. ========== |
