1）Unity 設定檔

<?xml version="1.0" encoding="utf-8"?><unity>  <typeAliases>    <typeAlias alias="singleton" type="Microsoft.Practices.Unity.ContainerControlledLifetimeManager,Microsoft.Practices.Unity"/>    <!--action的建構函式需要介面定義，依賴注入需要介面-->    <typeAlias alias="IFoo" type="MyTest.BizInterfaces.IFoo,MyTest.BizInterfaces"/>    </typeAliases>  <containers>    <container name="containerOne">      <types>        <!--action的建構函式需要介面定義，依賴注入需要介面-->        <type type="IFoo" mapTo="MyTest.Business.Foo, MyTest.Business"/>       </types>    </container>  </containers></unity>

2)UnityConfigurator

namespace MyTest.Common.IOC{    public class UnityConfigurator    {        public static IUnityContainer CreateContainer()        {            IUnityContainer parentContainer = new UnityContainer();            IUnityContainer childContainer = parentContainer.CreateChildContainer();            UnityConfigurationSection section = (UnityConfigurationSection)ConfigurationManager.GetSection("unity");            section.Configure(childContainer, "containerOne");            return childContainer;        }    }}

3)UnityControllerFactory

 namespace MyTest.Common.IOC{    public class UnityControllerFactory : DefaultControllerFactory    {        readonly IUnityContainer container;        public UnityControllerFactory(IUnityContainer container)        {            this.container = container;            var controllerTypes =               from t in Assembly.GetExecutingAssembly().GetTypes()               where typeof(IController).IsAssignableFrom(t)               select t;            foreach (var t in controllerTypes)            {#if DEBUG                System.Diagnostics.Debug.WriteLine("RegisterType: " + t.Name);#endif                container.RegisterType(t);            }        }        protected override IController GetControllerInstance(RequestContext requestContext, Type controllerType)        {            if (controllerType == null) return null;            return (IController)container.Resolve(controllerType);        }    }}

4) Under Register Routes

 public static void RegisterRoutes(RouteCollection routes)        {            AreaRegistration.RegisterAllAreas();            RegisterGlobalFilters(GlobalFilters.Filters);            Infratructure.RouteConfigurator.RegisterRoutes(RouteTable.Routes);            IUnityContainer container = UnityConfigurator.CreateContainer();            UnityControllerFactory factory = new UnityControllerFactory(container);            ControllerBuilder.Current.SetControllerFactory(factory);        }
