ここでの別の質問に続いて、オブジェクトを取得しました。実際のオブジェクト自体MainConfigではなく、そのオブジェクトの特定のプロパティを注入したいと考えています。私のモジュールメソッドMainConfigからの抜粋:Load

Bind<IConfig>()
    .ToMethod<IConfig>(ctx => MainConfig.Load())
    .InSingletonScope();

var config = Kernel.Get<IConfig>(); //this returns a fully-loaded IConfig, so I know this works

Bind<IProcessingBuffer>()
    .To<ProcessingBuffer>()
    .InSingletonScope()
    .WithConstructorArgument("processingInterval",
                             ctx => ctx.Kernel.Get<IConfig>().WinService.DataProcessingInterval);

のコンストラクタProcessingBufferは次のとおりです。

public ProcessingBuffer(int processingInterval, IProcessingResults procResults)

ただし、アプリケーションを起動しようとすると、が に注入されていないActivationExceptionため、が表示されます。例外は次のとおりです。processingIntervalProcessingBuffer

Ninject.ActivationException was unhandled
  Message=Error activating int
No matching bindings are available, and the type is not self-bindable.
Activation path:
  5) Injection of dependency int into parameter processingInterval of constructor of type ProcessingBuffer
  4) Injection of dependency ProcessingBuffer into parameter procBuffer of constructor of type MyCompanyDataService
  3) Injection of dependency MyCompanyDataService into parameter instance of constructor of type NinjectServiceHost{MyCompanyDataService}
  2) Injection of dependency NinjectServiceHost{MyCompanyDataService} into parameter dataHost of constructor of type MyCompanyWinService
  1) Request for MyCompanyWinService

Suggestions:
  1) Ensure that you have defined a binding for int.
  2) If the binding was defined in a module, ensure that the module has been loaded into the kernel.
  3) Ensure you have not accidentally created more than one kernel.
  4) If you are using constructor arguments, ensure that the parameter name matches the constructors parameter name.
  5) If you are using automatic module loading, ensure the search path and filters are correct.

私のWithConstructorArgumentラムダが呼び出されていることを確認し、それを追跡する方法はありますか? Ninject ソースをダウンロードしましたが、コールバックが使用されている場所を見つけるためにブレークポイントを設定する場所がわかりません。

このアプリケーションは、Ninject 3.0 と Ninject.Extensions.Wcf を使用して WCF TCP サービスをホストする Windows サービスです。

追加する編集:オブジェクトProcessingBuffer全体を取得して呼び出しIConfigを削除するようにコンストラクターを変更すると、オブジェクトが正常に挿入され、適切なプロパティにアクセスできます。ただし、オブジェクト全体を注入して依存関係を削除し、代わりに必要なデータのみを渡したいと考えています。WithConstructorArgumentIConfigIConfig

あなたはnotMyCompanyDataServiceのインスタンスを取ります。したがって、バインディングは適用されません。ProcessingBufferIProcessingBuffer
