GenoTipController must produce class according to the enum type. i have 3 class: _Company,_Muayene,_Radyoloji. Also i have CompanyView Class GetPersonel method. if you look GenoTipController my codes need refactoring. Can you understand me? i need a class according to ewnum type must me produce class. For example; case DataModelType.Radyoloji it must return radyoloji= new Radyoloji . Everything must be one switch case?

 public class GenoTipController
    {
        public _Company GenerateCompany(DataModelType modeltype)
        {
            _Company company = null;
            switch (modeltype)
            {
                case DataModelType.Radyoloji:
                    break;
                case DataModelType.Satis:
                    break;
                case DataModelType.Muayene:
                    break;
                case DataModelType.Company:
                    company = new Company(); 
                    break;
                default:
                    break;
            }

            return company;

        }

        public _Muayene GenerateMuayene(DataModelType modeltype)
        {
            _Muayene muayene = null;
            switch (modeltype)
            {
                case DataModelType.Radyoloji:
                    break;
                case DataModelType.Satis:
                    break;
                case DataModelType.Muayene:
                    muayene = new Muayene();
                    break;
                case DataModelType.Company:
                    break;
                default:

                    radyoloji = new Radyoloji();
                    break;
                case DataModelType.Satis:
                    break;
                case DataModelType.Muayene:
