Ninject, ASP.NET 및 사용자 지정 컨트롤

Question

현재 ASP.NET (표준, 은이 아니고 MVC)이 아니므로 Ninject를 IOC 컨테이너로 사용하고 있습니다.

이미 내 페이지에 종속성을 주입하는 데 사용하고 있습니다. 그러나 사용자 지정 컨트롤에 종속성을 주입하는 방법이 있는지 궁금합니다.

하지 않으면, 나는 Ninject에 연장 진행 얻을 것이다 : 나는 Ninject에 연장 끝내었고, Ninject.Framework.Web의 DLL에 두 개의 클래스를 추가 있도록

Answer 1

좋아요.

Answer 2

나는 페이지의 모든 컨트롤을 통해 반복, 일부 인터페이스를 구현하는 사람들을 주입하여이 문제를 해결했다.

인터페이스는 비어 :

:

protected virtual void RequestActivation() 
{ 
    KernelContainer.Inject(this); 
    InjectControls(this.Controls); 
} 

private void InjectControls(ControlCollection controls) 
{ 
    foreach (Control control in controls) 
    { 
     if (control is INinjectControl) 
      KernelContainer.Inject(control); 
     this.InjectControls(control.Controls); 
    } 
} 

은 몇 가지 단점이 있습니다

public interface INinjectControl { } 

나는이 인터페이스를 구현하는 모든 컨트롤을 주입 PageBase 및 MasterPageBase에 루프를 추가 한

• 이것은 OnInit가 실행될 때 이미 페이지에있는 컨트롤에서만 작동합니다. 프로세스에서 나중에 컨트롤을 추가하면 루프에 이 이미 실행되고 종속성이 주입되지 않습니다.
• Controls 컬렉션을 요청하기 때문에이 컨트롤은 일부 컨트롤에서 CreateChildControls()를 호출합니다. 이 메서드는 이제 수명주기의 훨씬 이전에 호출되므로 문제가 발생할 수 있습니다.
• 모든 컨트롤을 반복하므로 매우 효율적이지 않습니다.
