namespaces - How to use this class in my c# code -

how able use iaxaptawrapper class ?

 namespace axapta {     internal class axapta : iaxaptawrapper 

and

namespace axapta {     public class axthreadedwrapper: iaxaptawrapper     { 

my attempt ref dll library , then

use like

using (iaxaptawrapper ax = new axthreadedwrapper())          { 

the type or namespace name 'axthreadedwrapper' not found (are missing using directive or assembly reference?)

you need using directive not using statement. different.

a using directive allows omit namespace qualifiers in code. you'll need using directive iaxaptawrapper axthreadedwrapper. in same namespace.

a using statement wraps try-finally .dispose around block of code. use if object implements idisposable.

now have added internal class. means can't use in assembly (in normal way). default access modifier non-nested class internal you'll need replace public because want access assembly.
