使用依賴注入

Question

我繼承ApiController及以下初始化抽象類的對象是我重寫ExecuteAsync方法依賴注入，

public abstract class BaseController : ApiController 
{ 
    private IMyService _myService; 
    public PersonModel person; 
    protected BaseController(IMyService myService) 
    { 
     _myService = myService; 
    } 

    public override Task<HttpResponseMessage> ExecuteAsync(HttpControllerContext controllerContext, CancellationToken cancellationToken) 
    { 
     _myService.Initialize(person); 
    } 
} 

這是我的服務接口，

public interface IMyService 
{ 
    HttpResponseMessage Initialize(PersonModel person); 
} 

這裏是類，

public class MyService : IMyService 
{ 
    public HttpResponseMessage Initialize(PersonModel person) 
    { 
     //Initializing person model from db 
     return new HttpResponseMessage(HttpStatusCode.OK); 
    } 
} 

當我執行這個方法時，person對象在BaseController類仍然爲空。我應該改變什麼來初始化抽象類中的對象？

請檢查此線程，看看這個回答你的問題 - Registering implementations of base class with Autofac to pass in via IEnumerable

你將不得不適當地註冊您的抽象類的子類。
