这些保存之间有什么区别

ISaveService iSaveService = Kingdee.BOS.App.ServiceHelper.GetService();
IOperationResult result = iSaveService.Save(this.Context, info, objResults, OperateOption.Create());

ISaveService service = Kingdee.BOS.Contracts.ServiceFactory.GetSaveService(this.Context);
IOperationResult result =service.Save(this.Context, info, new DynamicObject[] { dynamicObject }, null, "Save");

Kingdee.BOS.ServiceHelper.BusinessDataServiceHelper.Save（）

this.View.InvokeFormOperation(FormOperationEnum.Save)

this.View.Model.Save();
