Using automapper to reverse map from dto - automapper

Question

Given the following code, is there anyway to get Automapper to do this instead of manually setting the properties? I'm trying to avoid having to do a one to one mapping at Mapper.CreateMap, since I;m constantly adding and removing fields from Contract, and at the moment have to remember to update this method with the changes.
private void MapModelToContract(ContractDto model, Contract contract)
{
contract.Id = model.Id;
contract.ContractDetail.BuyerCornhouseName = model.ContractDetailBuyerCornhouseName;
contract.ContractDetail.CnoCornLtdToBuyer = model.ContractDetailCnoCornLtdToBuyer;
contract.ContractDetail.CnoCornPartToCornLtd = model.ContractDetailCnoCornPartToCornLtd;
contract.ContractDetail.CnoSellerCornLtd = model.ContractDetailCnoSellerCornLtd;
contract.ContractDetail.CnoSellerCornPart = model.ContractDetailCnoSellerCornPart;
contract.ContractDetail.Commission = model.ContractDetailCommission;
contract.ContractDetail.ContractPrice = model.ContractDetailContractPrice;
contract.ContractDetail.SalesPriceToCornLtd = model.ContractDetailSalesPriceToCornLtd;
contract.ContractDetail.ContractedQuantity = model.ContractDetailContractedQuantity;
contract.ContractDetail.CostWarehouseToFob = model.ContractDetailCostWarehouseToFob;
contract.ContractDetail.Date = model.ContractDetailDate;
contract.ContractDetail.DeliveryDate = model.ContractDetailDeliveryDate;
contract.ContractDetail.FinalBuyerName = model.ContractDetailFinalBuyerName;
contract.ContractDetail.FinalSalesPrice = model.ContractDetailFinalSalesPrice;
contract.ContractDetail.Grade = model.ContractDetailGrade;
contract.ContractDetail.Notes = model.ContractDetailNotes;
contract.ContractDetail.PayableQuantity = model.ContractDetailPayableQuantity;
contract.ContractDetail.SalesShipmentPeriod = model.ContractDetailSalesShipmentPeriod;
contract.ContractDetail.SellerName = model.ContractDetailSellerName;
contract.ContractDetail.ToBePaidBy = model.ContractDetailToBePaidBy;
contract.ContractDetail.SalesBasis = model.ContractDetailSalesBasis;
contract.ContractDetail.SalesFreightValue = model.ContractDetailSalesFreightValue;
contract.CurrencyContract.Date = model.CurrencyContractDate;
contract.CurrencyContract.ExchangeRate = model.CurrencyContractExchangeRate;
contract.CurrencyContract.Number = model.CurrencyContractNumber;
contract.CurrencyContract.Value = model.CurrencyContractValue;
contract.CurrencyContract.IsAcc = model.CurrencyContractIsAcc;
contract.CurrencyContract.RepaidOn = model.CurrencyContractRepaidOn;
contract.CurrencyContract.RepaymentDate = model.CurrencyContractRepaymentDate;
contract.Discounts.Reason = model.DiscountsReason;
contract.Discounts.Value = model.DiscountsValue;
contract.DocumentControl.GuaranteeLetterReceived = model.DocumentControlGuaranteeLetterReceived;
contract.DocumentControl.PhotosReceived = model.DocumentControlPhotosReceived;
contract.GoodsStatus.ContainerNumber = model.GoodsStatusContainerNumber;
contract.GoodsStatus.EtaPort = model.GoodsStatusEtaPort;
contract.GoodsStatus.ExpectedDeliveryDate = model.GoodsStatusExpectedDeliveryDate;
contract.GoodsStatus.Port = model.GoodsStatusPort;
contract.GoodsStatus.ShippedStatus = model.GoodsStatusShippedStatus;
contract.GoodsStatus.VesselDeadline = model.GoodsStatusVesselDeadline;
contract.GoodsStatus.VesselName = model.GoodsStatusVesselName;
contract.GoodsStatus.HasSellerConfirmedRelease = model.GoodsStatusHasSellerConfirmedRelease;
contract.GoodsStatus.ReceivedShippingInstructions = model.GoodsStatusReceivedShippingInstructions;
contract.GoodsStatus.Notes = model.GoodsStatusNotes;
contract.NotaFiscalCornPart.Date = model.NotaFiscalCornPartDate;
contract.NotaFiscalCornPart.ExchangeRate = model.NotaFiscalCornPartExchangeRate;
contract.NotaFiscalCornPart.Number = model.NotaFiscalCornPartNumber;
contract.NotaFiscalSeller.Date = model.NotaFiscalSellerDate;
contract.NotaFiscalSeller.GoodsReleased = model.NotaFiscalSellerGoodsReleased;
contract.NotaFiscalSeller.Number = model.NotaFiscalSellerNumber;
contract.TransferToSeller.Date = model.TransferToSellerDate;
contract.TransferToSeller.TransferredFrom = model.ContractDetailBuyerCornhouseName;
contract.TransferToSeller.Value = model.TransferToSellerValue;
contract.CommissionLawyer.IsPaid = model.CommissionLawyerIsPaid;
}

Answer 1

The below mapper works for you.
If the Source (ContractDto) and Destination (Contract) have same property names.
Mapper.CreateMap<ContractDto, Contract>(); // Maps if ContractDto & Contract have same property names
If the Source (ContractDto) and Destination (Contract) have diff property names. Then
Mapper.CreateMap<ContractDto, Contract>()
.ForMember(destination => destination.BuyerCornhouseName, options => options.MapFrom(source => source.ContractDetailBuyerCornhouseName))
.ForMember(destination => destination.CnoCornLtdToBuyer, options => options.MapFrom(source => source.ContractDetailCnoCornLtdToBuyer));
// Explicitly you have specify for other properties also
