Unity (C # IOC framework) Usage Summary

Unity here refers to the completion of dependency injection of unity rather than the game engine.

Originally the project completed dependency injection with spring.net, but Spring.net has been a long time no one to maintain, so Microsoft's official launch of Unity as a substitute for spring.net one of the best candidates.

Simple Console Demo:

Start with a new console app, and NuGet searches for unity and installs it.

usingSystem; usingUnity;usingunity.attributes;namespaceconsoleapp1{ Public classIndex {[Dependency] Public VirtualIuserservice UserService {Set;Get; }  Public Static voidMain (string[] args) {            varcontainer =NewUnityContainer (); Container. Registertype<iuserservice, userservice>(); Register Iuserservice UserService= Container. Resolve<iuserservice>();        Get Userservice.hello (); }    }     Public InterfaceIuserservice {voidHello (); }    classUserservice:iuserservice { Public voidHello () {Console.WriteLine ("Hello"); }    }}

Using Unity in asp:

1. New ASP. NET MVC application, NuGet installation Unity.mvc

2, the new class library BLL, IBLL, completed after the directory as follows:

3. BLL new USERSERVICE,IBLL New Iuserservice, implement Hello method

namespace ibll{    publicinterface  iuserservice    {         string  Hello ();    }}

using IBLL; namespace bll{    publicclass  userservice:iuserservice    {        public string Hello ()        {            return"hello";}}    }

4: Fill in the configuration in Global.asax.cs. Examples are as follows:

usingSYSTEM.WEB.MVC;usingSystem.Web.Optimization;usingSystem.Web.Routing;usingBLL;usingIBLL;usingUnity;usingUNITY.ASPNET.MVC;namespacewebapp{ Public classMvcApplication:System.Web.HttpApplication {protected voidApplication_Start () {arearegistration.registerallareas ();            Filterconfig.registerglobalfilters (globalfilters.filters);            Routeconfig.registerroutes (routetable.routes);            Bundleconfig.registerbundles (Bundletable.bundles); varcontainer =Buildunitycontainer (); Customize the Buildunitycontainer method to get the container dependencyresolver.setresolver (NewUnitydependencyresolver (container)); } Iunitycontainer Buildunitycontainer () {UnityContainer container=NewUnityContainer (); Container. Registertype<iuserservice, userservice>();returncontainer; }    }}

5. Obtain the UserService class in control and use

usingSYSTEM.WEB.MVC;usingIBLL;namespacewebapp.controllers{ Public classHomecontroller:controller {PrivateIuserservice UserService; PublicHomeController (Iuserservice userservice) { This. UserService =UserService; Using constructor injection        }         PublicActionResult Index () {stringstr =Userservice.hello (); returnContent (str); }    }}

This completes one of the simplest MVC demos.
