I'm trying to save data from a custom object into the profile object, but it
is not structured the way that I want.
I'm trying to get the custom object to serialize as xml to a Profile object
like so:
<Teachers>
<Teacher>
<Classes>
<Class>
<Students>
<Student>
I have the nesting correct down through Class, but I haven't been able to
get the Students and Student to nest properly...they actually nest under
Teacher, the same as the Classes level.
There are three files below: 1) aspx code, 2) custom object, 3) the xml
output to the Profile table in the ASPNETdb.
I suppose that the custom object is not written correctly to attain the
desired nesting ...or is it something else?

Profile.Teacher s.Add(new School.Teacher( TextBox_Add_Tea cher.Text,
Profile.Classes ));
