What are the different ways to implement dependency injection and their advantages in C#?
The process of injecting (converting) coupled (dependent) objects into decoupled (independent) objects is called Dependency Injection.
Types of Dependency Injection
There are four types of DI:
1.Constructor Injection
2.Setter Injection
3.Interface-based injection
4.Service Locator Injection
Constructor Injection
Constructor is used to interface parameter that exposed through the parameterized contractor.
It injects the dependencies through a contractor method as object creation other classes.
Setter Injection
Getter and Setter Injection injects the dependency by using default public properties procedure such as Gettter(get(){}) and Setter(set(){}). T
Interface Injection
Interface Injection is similar to Getter and Setter DI, the Getter and Setter DI uses default getter and setter but Interface Injection uses support interface a kind of explicit getter and setter which sets the interface property.
Service Locator Injection
Service Locator Injection is also known as Dependency Absorption. It is used to replacement of new operator. It hides the class dependency by invoking methods directly (without creating object).
Advantages of DI
Reduces class coupling
Increases code reusability
Improves code maintainability
Improves application testing
Centralized configuration
Drawback of dependency Injection
The main drawback of dependency injection is that using many instances together can become a very difficult if there are too many instances and many dependencies that need to be resolved.
