Root table of references in GC

[ShervanN]

Hi,

Page 340, CHAPTER 13 Managed and Unmanaged Memory, below Garbage Collection you wrote "The GC finds all referenced objects from a root table of references and continues to a tree of referenced objects."
But didn't explain about root table of references

When you create an object, e.g. from this Main method, the references p1 and p2 are added to the root table of references.

Person p1 = new();
Person p2 = new();
//...

If the Person object itself creates an inner object, such as an Address object, which is stored in a member of the Person type, the reference to the address is not stored on the root table. This reference is found in the tree of referenced objects.
