Elegant way to to modify two different classes with one set of code

               public class MasterProgram
                {
                        public class Program
                        {
                                public ItemBudget Budget {get;set;}
                                public ItemClass Class {get;set;}
                                public DateTime StartDate {get;set;}
                                public DateTime EndDate {get;set;}
                        }
                        
                        public class ProgramWrk
                        {
                                public ItemBudgetWrk Budget {get;set;}
                                public int Class {get;set;}
                                public DateTime StartDate {get;set;}
                                public DateTime EndDate {get;set;}                              
                        }
                        
                        public EnumStatus Status {get;set;}
                        public string Title {get;set;}
                        public string ShortDescription {get;set;}
                        public EntitySet<Program> Programs {get;set;}
                        public EntitySet<ProgramWrk> ProgramsWrks {get;set;}
                        
                        public MasterProgram()
                        {
                                Programs = new EntitySet<Program>();
                                ProgramWrks = new EntitySet<ProgramWrk>();
                        }
                }

Based on the master program status, I need to load specific collection on a grid, then when the user saves changes, I sent the master program object to a method to save the modified properties.

I don't want to use if then statements or duplicate code.

Thanks,
