Write a code to implement dependency injection in C#.

Question

Mosharaf Hossain · Accepted Answer

You can just write a constructor in ASP.MVC controller like this:

private IEmployeesRepository _employeesRepository;

public EmployeesController(IEmployeesRepository employeesRepository)
{
     _employeesRepository = employeesRepository;
}

When using any IoC container to map IEmployeesRepository to EmployeesRepository, this constructor will get an EmployeesRepository object during initialization, which will be done through constructor injection. We can then use _employeesRepository in the controller actions.
