I have this class:

namespace TCSCloud.Domain.RepairOrder.Model
{
    public class UpdateRepairOrder : Base.Base
    {
        public DateTime CreateDate { get; set; }
        public string CreateUser { get; set; }
        public DateTime LastUpdateDate { get; set; }
        public string LastUpdateUser { get; set; }
        public int TenId { get; set; }
        public int WorordId { get; set; } // Primary Key
        public string EstimateNumber { get; set; }
        public string WoNumber { get; set; }
        public string WoSource { get; set; }
        public string ReferenceNumber { get; set; }
        public string PoNumber { get; set; }
        public int CusId { get; set; }
        public int CusIdInvoiceTo { get; set; }
        public int CusIdWo { get; set; }
        public string CustomerName { get; set; }
        public string ContactName { get; set; }
        public string WoLocation { get; set; }
        public int CuslocId { get; set; }
        public int WorordtypId { get; set; }
        public int WorordcatId { get; set; }
        public int WorordunistaId { get; set; }
        public int ShosupId { get; set; }
        public int FacId { get; set; }
        public int WarId { get; set; }
        public int UniId { get; set; }
        public int ReeId { get; set; }
        public int OtReading { get; set; }
        public int RtReading { get; set; }
        public int HuboReading { get; set; }
        public string HuboReadingUom { get; set; }
        public string EstimateFlag { get; set; }
        public DateTime EstimateDate { get; set; }
        public DateTime EstimateCompleteDate { get; set; }
        public DateTime EstimateIntApprovedDate { get; set; }
        public DateTime EstimateCustomerHoldDate { get; set; }
        public DateTime EstimateCustApprovedDate { get; set; }
        public string EstimateNotes { get; set; }
        public DateTime WoDate { get; set; }
        public DateTime Completed_date { get; set; }
        public DateTime ApprovedDate { get; set; }
        public DateTime TransmitTimestamp { get; set; }
        public DateTime VoidDate { get; set; }
        public int TotalLabour { get; set; }
        public int TotalParts { get; set; }
        public int TotalShopsupply { get; set; }
        public int TotalSurcharge { get; set; }
        public int TotalTax { get; set; }
        public string Notes { get; set; }
        public string SystemNotes { get; set; }
        public string MobileNotes { get; set; }
        public string VoidNotes { get; set; }
        public int UseIdPreparedDy { get; set; }
        public int UseIdApprovedBy { get; set; }
        public int UseIdVoidedBy { get; set; }
        public string WoWsStatus { get; set; }
        public string UnitNumber { get; set; }
        public string UnitLicensePlate { get; set; }
        public string UnitSerialVin { get; set; }
        public string UnitReeferNumber { get; set; }
        public int UnitUnimakId { get; set; }
        public int UnitUnimodId { get; set; }
        public string UnitNotes { get; set; }
        public string CertificateLetter { get; set; }
        public int CertificateNumber { get; set; }
        public DateTime CertificateDate { get; set; }
        public string CertificateOther { get; set; }
        public string LastInsertUsername { get; set; }
        public string LastUpdateUsername { get; set; }
        public DateTime LastInsertDate { get; set; }
    }
}

I added its namespace as dll in "RepairOrderModel.cs",

using System.Linq;
using System.Text;
using System.Threading.Tasks;
using TCSCloud.Domain.RepairOrder;
using TCSCloud.Domain.RepairOrder.Model;

namespace TCSCloud.Domain.RepairOrderManagement.Model
{
    public class RepairOrderModel
    {
        UpdateRepairOrder UpRepOrd = new UpdateRepairOrder();
    }
}

now i want to write some logic to update (Update Query) all values of "UpdateRepairOrder" in RepairOrderModel but couldn't find out the way, so how ? even with dummy values ? via linq to sql ? or anything ?
