Using Ninject Dependency Injection in MVC

Using Ninject injection in. NET MVC is mainly divided into the following steps:

1. Using the NuGet package to add the Ninject reference, I added the current version 3.34
2. Under the App_start folder, create the Ninjectcontrollerfactory class
3. Add the following code to global
4. The main use of the project is interface injection, can refer to the Iuser invocation example

  Public classNinjectcontrollerfactory:defaultcontrollerfactory {PrivateIkernel Kernel;  Publicninjectcontrollerfactory () {Kernel=NewStandardkernel ();        Addbindings (); }        protected OverrideIController getcontrollerinstance (RequestContext requestcontext, Type controllertype) {returnControllertype = =NULL?NULL: (IController) Kernel.get (Controllertype); }         Private voidaddbindings () {Kernel.bind<IUser> (). To<user>(); }         Public ObjectGetService (Type servicetype) {return  This.        Kernel.tryget (servicetype); }         Publicienumerable<Object>getservices (Type servicetype) {return  This.        Kernel.getall (servicetype); }    }

 protected  void   Application_Start () {log4net.            Config.XmlConfigurator.Configure ();  //  set up controller factory   ControllerBuilder.Current.SetControllerFactory (new   ninjectcontrollerfactory ());             Arearegistration.registerallareas ();            Filterconfig.registerglobalfilters (globalfilters.filters);            Routeconfig.registerroutes (routetable.routes);        Bundleconfig.registerbundles (Bundletable.bundles); }

 Public class Homecontroller:controller    {        [ninject.inject]        publicgetset;}        [Allowlogin]          Public ActionResult Login (string UserName,string  userpwd)        {           var Usermodel = user. Getbylogin (UserName,userpwd
        
    }
