Handler

 

Scenario:

Create handlers to handle user creation based on type

Solution:

• IUserHandler
  public interface IUserHandler
      {
          void CreateUser(User user);
      }
  UserHandlers
  public class InternalUserHandler : IUserHandler
      {
          public void CreateUser(User user)
          {
              // Create Internal user
          }
      }
  
      public class ExternalUserHandler : IUserHandler
      {
          public void CreateUser(User user)
          {
              // Create External user
          }
      }
  
      public class UserHandler
      {
          public UserHandler()
          {
          }
  
          public static void CreateUser(User user)
          {
              .Get<IUserHandler>().InternalCreateUser(user);
          }
  
          private void InternalCreateUser(User user)
          {
              try
              {
                  var handler = .Get<IUserHandler>(user.Type.ToString());
                  handler.CreateUser(elasticIndexerEntity);
              }
              catch (Exception e)
              {
                  throw;
              }
          }
      }

• Call

static void Main(string[] args)
    {
        var user = new User<Task>();
        UserHandler.CreateUser(user);
    }

    //Ninject
    Bind<IUserHandler>().To<InternalUserHandler>().InSingletonScope().Named(User.Type.ToString());
