用更復雜的場景瞭解Ninject

Question

我正在嘗試使用ninject來...做好ninject的工作..

基本上注入不會發生。

在我的代碼中，我在我的「測試」中創建內核，期望一個IDrinkCan實現以某種方式進入我的CokeComsumer類。

我想我錯過了這裏的東西..因爲當我在CokeConsumer構造函數上放置一個斷點時，IDrinkCan爲null。

namespace testThing 
{ 
public class MyDependencyKernel 
{ 
    public static IKernel DependencyKernel { get; internal set; } 

    public MyDependencyKernel() 
    { 
     DependencyKernel = new StandardKernel(new MyNinjectModule()); 
    } 

    public MyDependencyKernel(NinjectModule ninjectModule) 
    { 
     DependencyKernel = new StandardKernel(ninjectModule); 
    } 
} 

public class MyNinjectModule : NinjectModule 
{ 
    public override void Load() 
    { 
     Bind<IDrinkCan>().To<Coke>(); 
    } 
} 

public interface IDrinkCan 
{ 
    void OpenCan(int canSize); 
    void DrinkSome(int milliletres); 
    bool IsEmpty(); 
} 

public class Coke : IDrinkCan 
{ 
    private int _capacity; 
    private bool _isEmpty; 

    public void OpenCan(int canSize) 
    { 
     _capacity = canSize; 
    } 

    public void DrinkSome(int milliletres) 
    { 
     if (!_isEmpty) _capacity -= milliletres; 
     if (_capacity < 0) _isEmpty = true; 
    } 

    public bool IsEmpty() 
    { 
     return _isEmpty; 
    } 
} 

public class CokeConsumer 
{ 
    //[Inject] 
    public IDrinkCan Drink { get; set; } 

    [Inject] //drink is not being injected 
    public CokeConsumer(IDrinkCan drink) 
    { 
     Drink = drink; 
     Drink.OpenCan(330); 
    } 

    public CokeConsumer() 
    { 
     Drink.OpenCan(330); 
    } 

    public void DrinkSomeCoke(int amount) 
    { 
     Drink.DrinkSome(amount); 
    } 
} 

[TestFixture] 
public class SomeTestClass 
{ 
    [Test] 
    public void DoSomeTest() 
    { 
     MyDependencyKernel kernel = new MyDependencyKernel(); 

     CokeConsumer steve = new CokeConsumer(); 
     steve.DrinkSomeCoke(100); 
    } 
} 
} 

Answer 1

這是錯誤的！

[Test] 
public void DoSomeTest() 
{ 
    MyDependencyKernel kernel = new MyDependencyKernel(); 

    CokeConsumer steve = new CokeConsumer(); 
    steve.DrinkSomeCoke(100); 
} 

我應該從內核中獲得CokeConsumer !!!!

即

var steve = kernel.DependencyKernel.Get<CokeConsumer>();
