Unity -- IOC

1. Define a data interface and two data Implementation classes first}View Code}View Code}View Code2. client call --- direct call

              Main(                            MSDAL.Student studentMS =               Console.WriteLine( + studentMS.Writing() +                             　　　　　}　　
　　　　}

3. implement client call --- Interface Programming dependency Abstraction

              Main(        　　　　              IStudent student =  MSDAL.Student();                           Console.WriteLine( + student.Writing() +      }     

4. implement client call --- reflection decoupling

              Main(                             assemblyName = ;              className = assemblyName + ;                          IStudent studentReflection =             Console.WriteLine( + studentReflection.Writing() +      }     

5. implement client call --- reflection + configuration file

             Main(                             assemblyNameConfiguration = ConfigurationManager.AppSettings[];               classNameConfiguration = assemblyNameConfiguration + ;                           IStudent studentConfiguration =             Console.WriteLine( + studentConfiguration.Writing() +      }            

6. implement client call --- Spring. Net object creation decoupling

You need to add Spring. Core. dll Assembly reference

               Main(       　　　　             IApplicationContext SpringContext = Spring.Context.Support.ContextRegistry.GetContext();             IStudent studentSpring = (IStudent)SpringContext.GetObject();             Console.WriteLine( + studentConfiguration.Writing() +      }

Configuration File

View Code7. implement client call --- Unity creates object decoupling

You need to add Microsoft. Practices. Unity. dll and Microsoft. Practices. Unity. Configuration. dll Assembly references.

              Main(                            IUnityContainer mycontainer =  UnityContainer();             UnityConfigurationSection section = (UnityConfigurationSection)ConfigurationManager.GetSection();             section.Configure(mycontainer);             IStudent studentUnity = mycontainer.Resolve<IStudent>();             Console.WriteLine( + studentUnity.Writing() +      }
