c# - Xml deserialize does unwanted initialization -

-

i have class contains list. in constructor add default object list.

class {    list<b> list;    public a()    {        list = new list<b>();        b b = new b();        list.add(b);    } }

but seems when xmlserializer deserialize xml file containing a object, loaded object have 2 b object in list. guess calls constructor again , constructor adds next b

why happens? how can avoid it?

try overloaded constructor. 1 takes nothing , adds nothing list, can used when deserializing. other takes b , adds b list.
