Question

我如何使用注释来注入，这类似于Spring MVC的功能

public class AccountController :Controller
{

[Injected] // Need like this annotation
private AccountService _accountService;

public AccountController(){

}

}

Answer 1

您可以使用Unity Container

以下是一个例子：

public class MyObject
{
  private SomeOtherObject _dependentObject;

  [Dependency]
  public SomeOtherObject DependentObject 
  {
    get { return _dependentObject; }
    set { _dependentObject = value; }
  }
}

这是决议：

IUnityContainer uContainer = new UnityContainer();
MyObject myInstance = uContainer.Resolve<MyObject>();

// now access the property containing the dependency
SomeOtherObject depObj = myInstance.DependentObject;

Answer 2

在.Net核心应用程序中，无需提及注入注释。您需要将您的服务更改为接口驱动。

在解决方案启动页面中，在services.AddMvc（）;

之前添加以下显示的代码

        services.AddTransient<IInterface, Service>();

并在控制器中进行更改

public class AccountController :Controller
{ 
   private IAccountService _accountService;
   public AccountController(IAccountService accountService){
       _accountService = accountService;
   }
}

通过Spring MVC之类的注释进行Asp.Net核心依赖注入
