How to implement dependency injection using Interface-based injection in C#?

Csharp Server Side Programming Programming

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 −

Constructor Injection
Setter Injection
Interface-based injection
Service Locator Injection

Interface Injection

Interface Injection is similar to Getter and Setter DI, the Getter, and Setter DI use default getter and setter but Interface Injection uses support interface a kind of explicit getter and setter which sets the interface property.

Example

public interface IService{
   string ServiceMethod();
}
public class ClaimService:IService{
   public string ServiceMethod(){
      return "ClaimService is running";
   }
}
public class AdjudicationService:IService{
   public string ServiceMethod(){
      return "AdjudicationService is running";
   }
}
interface ISetService{
   void setServiceRunService(IService client);
}
public class BusinessLogicImplementationInterfaceDI : ISetService{
   IService _client1;
   public void setServiceRunService(IService client){
      _client1 = client;
      Console.WriteLine("Interface Injection ==>
      Current Service : {0}", _client1.ServiceMethod());
   }
}

Consuming

BusinessLogicImplementationInterfaceDI objInterfaceDI =
new BusinessLogicImplementationInterfaceDI();
objInterfaceDI= new ClaimService();
objInterfaceDI.setServiceRunService(serviceObj);
