To assist class debugging, Visual Studio .NET allows the programmer to expand and
view all data members and properties of a class, including Private members. In any of
the four windows (i.e., Watch, Locals, Autos and Me), a class that has data members is
displayed with a plus (+) next to it (Fig. D.23). Clicking the plus box displays all of the
object’s data members and their values. If a member references an object, the object’s data
members also can be listed by clicking the object’s plus box.
