ASP.NET MVC使用Ninject的方法教程

public interface ITest
{
 Decimal ValueProducts(IEnumerable<Product>products) ;
}
public class Test:ITest
{
 public Decimal ValueProducts(IEnumerable<Product>products) 
 {
 return products.sum(p=>p.Price);
 }
}
public class ShoppingCart
{
 private ITest test;
 public IEnumerable<Product>products{set;get;}
 public ShoppingCart( ITest test)
 {
 this.test=test;
 }
 public Decimal result(products);
}

public ActionResult Index(){
 ITest IT=new Test();
 ShoppingCart cart=new ShoppingCart(IT);{Products=products};
 Decimal total=IT.result();
 return View(total);
}

//在控制器
public ActionResult Index()
{
 1:创建一个Ninject的内核
 IKernel ninject=new StandardKernel();
 2:就是配置Ninject内核,其实就是将实现类和接口类绑定在一起
 ninject.Bind<ITest>().To<Test>();
 3:最后一步就是使用Ninject创建一个对象了
 ITest IT=ninject.Get<ITest>();
}

public class NinjectResolver:IDependencyResolver
{
 private IKernel kernel;
 public NinjectResolver(IKernel kernel)
 {
 this.kernel=kernel; 
 AddBinding();
 }
 public IEnumerable<Object> GetServices(Type serviceType)
 {
 return kernel.GetAll(serviceType);
 }
 public Object GetService(Type serviceType)
 {
 return kernel.TryGet(serviceType);
 } 
 void AddBinding()
 {
 kernel.Bind<ITest>().To<Test>();
 }
}

private ITest test;
public HomeController(ITest test)
{
 this.test=test;
}
public ActionResult Index(){
 ShoppingCart cart=new ShoppingCart(IT);{Products=products};
 Decimal total=IT.result(); return View(total);
}

public interface IHelper
 {
 Decimal ApplyDiscount(Decimal totalParam); 
 }
 public class Helper : IHelper
 {
 public Decimal DiscountSize { set; get; } 
 
 public decimal ApplyDiscount(decimal totalParam)
 {
 return (totalParam - (discountparam / 100m * totalParam));
 }
 }

private void AddBindings()
 {
 kernel.Bind<ITest>().To<Test>();
 
 kernel.Bind<IHelper>().To<Helper>().WithPropertyValue("DiscountSize", 50M); kernel.Bind<IHelper>().To<Helper>().WithConstructorArgument("discountparam", 50M);
 }
