.NET Forum / .NET Framework / Performance / January 2005garbage collections in circular references
If I have an object MYCONTROL that has a reference to object A that subscribes to an event of object B and has a reference to object B in its Items collection that is a member of object A. Object B also has a reference varialbe Parent that points to object A. If I null the reference to object A in MYCONTROL, will object A and B get garbage collected or will they live forever in their circular reference? > If I have an object MYCONTROL that has a reference to object A that > subscribes to an event of object B and has a reference to object B in > its Items collection that is a member of object A.

A circular reference in unreferenced data doesn't trouble the garbage collector at all. That is, if no live data refers to A or B, they will be collected, no matter how many different ways they refer to each other.
