.net - How can I inject run-time parameters along with a volatile dependency into a constructor with Castle Windsor? -

some of classes have constructor similar following:

public class mycomponent : basecomponent, imycomponent {     public mycomponent(ipostrepository postsrepo, int postid, icollection<string> filenames)     {         // ...     } } 

ipostrepository volatile dependency, can initialized @ application start. postid , filenames arguments known @ run time.

how can use castle windsor (3.2.0, if matters) handle injection of ipostrepository dependency while still allowing run-time constructor parameters?

(while 1 approach might refactor mycomponent, significant undertaking many other portions of code refer mycomponent.)

here's i've gotten far: think need create mycomponentfactory. interface of mycomponentfactory like

public interface imycomponentfactory {     imycomponent create(params object[] args); } 

this imycomponentfactory injected layer above (the controller in case) so:

public class mycontroller : controller {     private imycomponentfactory _mycomponentfactory;      public mycontroller(imycomponentfactory mycomponentfactory)     {         _mycomponentfactory = mycomponentfactory;     }      public actionresult myaction(int postid)     {         list<string> filenames = new list<string>();         // ...          // creates new instance of resolved imycomponent ipostrepository injected imycomponentfactory , run time parameters.         imycomponent mycomponent = _mycomponentfactory.create(postid, filenames);           // stuff mycomponent          return view();     } } 

finally, have attempted let castle windsor create factory implementation registering imycomponentfactory in composition root so:

// add factory facility container.addfacility<typedfactoryfacility>();  container.register(component.for<imycomponentfactory>().asfactory()); 

doing results in dependencyresolverexception message of

could not resolve non-optional dependency 'playground.examples.components.mycomponent' (playground.examples.components.mycomponent). parameter 'postid' type 'system.int32'

the error makes sense, , i'm guessing need create custom implementation of imycomponentfactory, i'm not sure how go it.

why can't following:

public class mycomponentfactory : imycomponentfactory {     private ipostrepository postrepository;      public mycomponentfactory(ipostrepository postrepository)     {        this.postrepository = postrepository;     }      public imycomponent create(int postid, icollection<string> filenames)     {                     return new mycomponent(this.postrepository, postid, filenames);     } } 

i use explicit parameters in create method.

then register mycomponentfactory against interface imycomponentfactory (as singleton)
