asp.net MVC uses ninject to implement IOC dependency injection

First, install the Ninject framework with the following Nuget command:

Create an interface:

Then implement this interface:

We create a folder called Infrastructure under the WebUI project, add a factory class called NinjectControllerFactory to it, the code is as follows:

Login is visible.

ninjectKernel.Get(controllerType) in the above code can get a Controller instance. If manually instantiating the Controller class is a very complicated process, we don't know if the Controller class has a constructor with parameters, or what type of argument the constructor is. To use Ninject, you only need to use one of the above Get methods, and Ninject will automatically handle all dependencies internally and intelligently create the objects we need.

Once the Controller Factory class is created, we need to tell MVC to use our NinjectControllerFactory class to create the Controller object, to do this, we need to add the following code to the Application_Start method of the Global.asax file:

Login is visible.

We create a new class called ControllerBase in the controller folder, and the code is as follows:

Login is visible.

Then, we modify the controller to integrate the ControllerBase class, ok, done!
