List<T> add method in C# -

as know. list add method works below.

list<string> cities = new list<string>(); cities.add("new york"); cities.add("mumbai"); cities.add("berlin"); cities.add("istanbul"); 

if designed data structure this

list<object> lstobj = new list<object>();             if (true)  // string members {     cities.add("new york");     cities.add("istanbul"); } else // list obj members here  {     list<object> alistobject= new list<object>();     cities.add(alistobject);  // how handle this? } 

does list add method works or not if add different types members in same function.

you can't add list<object> list<string>. thing can add list of strings strings (or null references). use instead:

list<object> cities = new list<object>(); 

but seems bad design. when use object generic type of collection lose benefits of type-safety.

for parsing xml i'd suggest @ xmldocument.
