Ninject(开源IOC)的简单封装

1.NuGet获取Ninject.dll

 

 

 

 

.NET技术交流群 199281001 .欢迎加入。

 

 

2.全局注册  Global.asax.cs

 

//注册Ninject依赖注入全局解析器
2  GlobalConfiguration.Configuration.DependencyResolver = new System.Web.Http.Dependencies.NinjectDependencyResolver(new Ninject.StandardKernel());

 

3.辅助类

 2 using IBLL;
 3 using Ninject;
 4 using System.Web.Http.Dependencies;

 6 namespace System.Web.Http.Dependencies
 7 {
 8     //Author:GaoBingBing
 9     public class NinjectDependencyResolver : NinjectDependencyScope, IDependencyResolver
10     {
11         [Ninject.Inject]
12         private IKernel kernel;
13         public NinjectDependencyResolver()
14         {
15             
16         }
17         public NinjectDependencyResolver(IKernel kernel)
18         {
19             this.kernel = kernel;
20             this.kernel.Settings.InjectNonPublic = true;
21             this.AddBinds();
22         }
23 
24         private void AddBinds()
25         {
26              
27             //由此添加你的注入
28             this.kernel.Bind<IXX>().To<XX>();
29          }
30         //开始处理
31         public IDependencyScope BeginScope()
32         {
33             return new NinjectDependencyScope(this.kernel.BeginBlock());
34         }
35 
36 
37 
38     }
39 }

NinjectDependencyScope

4.Config

 

//Author:GaoBingBing
public class DIConfig
{
public static T CreateInstance<T>() where T : class
{
System.Web.Http.Dependencies.IDependencyResolver resolver = System.Web.Http.GlobalConfiguration.Configuration.DependencyResolver;
return resolver.BeginScope().GetService(typeof(T)) as T;
}

}

DIConfig

5.调用

private IXX   _x=DIConfig.CreateInstance<IXX>();
