Factory class implementation

[beantownace]

Hello all,

I am trying to figure this out so I can move a switch statement into the factory side versus in the controller I have. I want to somehow use generics with this so I can just have one method that will return the correct worker type based on the switch statement. Thanks for any assist on this one.

Code example:

// Controller:
 
  public CustomerController(ICustomerFactory customerFactory)
  {
     _customerFactory = customerFactory ?? throw new ArgumentNullException(nameof(customerFactory));
  }

  public override async Task<IActionResult> GetCustomerStatus([FromBody] CustomerRequest request)
  {
     try
     {
       //I WANT TO MOVE THIS SWITCH STATEMENT TO THE FACTORY CLASS SOMEHOW AND BE ABLE TO USE GENERICS TO HANDLE WHAT INSTANCE TO PASS BACK AS SHOWN IN CUSTOMERFACTORY BELOW AS
       //I REPEAT THIS SWITCH THROUGHOUT THE CONTROLLER SO HOPING I CAN USE ONE METHOD AND
       switch (request.Oms)
       {
              case Customer.CompanyAEnum:
                     await _customerFactory.CompanyAWorker().GetCustomerStatus(request);
                     break;

              case Customer.CompanyBEnum:
                     await _customerFactory.CompanyBWorker().GetCustomerStatus(request);
                     break;
              default:
                     break;

       }

       return Ok();
     }
     catch (Exception ex)
     {
           return BadRequest(ex.Message);
     }
  }
 
 //Factory Class:
 
 public class CustomerFactory : ICustomerFactory
 {
      public CompanyA.Workers.Interfaces.ICustomerWorker CompanyAWorker()
      {
             return new CompanyA.Workers.CustomerWorker();
      }

      public CompanyB.Workers.Interfaces.ICustomerWorker CompanyBWorker()
      {
             return new CompanyB.Workers.CustomerWorker();
      }

 }
  
 //Factory Interface:
 
 public interface ICustomerFactory
 {
   CompanyA.Workers.Interfaces.ICustomerWorker CompanyAWorker();

   CompanyB.Workers.Interfaces.ICustomerWorker CompanyBWorker();
 }

This has nothing to do with generics. This is a simple refactoring of creating a factory method that takes the enum values parameter, and returns an appropriate class that implements ICustomerWorker.
