c# - How to get the instance into which the activated object has been injected at activation time? -

i'm trying utilize ninject me build possible tree of service classes. i'd inject ilogger instance using incallscope child service class use same logger.

the logger implementation has property called rootservice, point upper-most service class instance uses logger. use information when categorizing logged events according service class has come (child classes not define "log scope", hence use incallscope).

can fine-tune ilogger ninject binding have kind of callback when ilogger instance activated, , had there instance too, got injected? there set rootservice property of logger.

there's onactivation binding extension callback executed when ilogger instanciated. can following:

public class test {     [fact]     public void foo()     {         var kernel = new standardkernel();         kernel.bind<service>().toself();          kernel.bind<logger>().toself()             .onactivation((ctx, logger) =>                 logger.initalize(ctx.request.target.member.declaringtype));          var service = kernel.get<service>();          service.logger.rootservice.should().be(typeof(service));     } }  public class logger {     public type rootservice { get; private set; }      public void initalize(type rootservice)     {         this.rootservice = rootservice;     } }  public class service {     public logger logger { get; private set; }      public service(logger logger)     {         logger = logger;     } } 

however, icontext not provide access "parent" instance, can access type it's injected into, not instance.

also, if should enough, there's no need use onactivation extension, should able this:

public class test {     [fact]     public void foo()     {         var kernel = new standardkernel();         kernel.bind<service>().toself();          kernel.bind<logger>().toself()             .withconstructorargument(                 typeof(type),                 ctx => ctx.request.target.member.declaringtype);          var service = kernel.get<service>();          service.logger.rootservice.should().be(typeof(service));     } }  public class logger {     private readonly type _rootservice;      public logger(type rootservice)     {         _rootservice = rootservice;     }      public type rootservice     {         { return _rootservice; }     } }  public class service {     public logger logger { get; private set; }      public service(logger logger)     {         logger = logger;     } }
