c# - Binding one class to several interfaces as singleton -

i have instance 2 interfases iinterface1 , iinterface2,

public interface iinterface1 {...} public interface iinterface2 {...}  

and 1 implementation of these interfaces implclass.

public class implclass : iinterface1, iinterface2 {...} 

i have sure application has 1 instance of implclass, used iinterface1 , iinterface2. i'm using ninject dependency injection. qustion is: code below meet requirements?

... bind<iinterface1>().to<implclass>().using<singletonbehavior>(); bind<iinterface2>().to<implclass>().using<singletonbehavior>(); ... 

or code create 2 instances of implclass, eash interface?

with ninject can this:

var impl = new impl(); container.bind<iint1>().tomethod(c => impl); container.bind<iint2>().tomethod(c => impl); 

when impl class has dependencies can't ninject inject, can this:

container.bind<impl>().toself().insingletonscope(); container.bind<iint1>().tomethod(c => c.kernel.get<impl>()); container.bind<iint2>().tomethod(c => c.kernel.get<impl>());  

nice , clean.
