Refactoring C# Code for Conversion

I have the class below and I'd like to factor out the common piece (the conversion of a DAL PolicytblPricingModelPricingSavedPricing object to a domain Pricing object). Specifically, this...

select new Pricing
{
   PricingModelID = q.PricingModelID,
   PolicyFaceAmount = q.FaceAmt.HasValue ? q.FaceAmt.Value : 0
}

Open in new window


Can someone provide some guidance on how to accomplish this? Is it possible? I am having difficulty figuring out how to extract this piece.

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using PM.DAL;
using PM.Common.Domain;
using System.Linq.Expressions;

namespace PM.BusinessLogic.Converters
{
    public static class TblSavedPricingConverter
    {
        public static IQueryable<Pricing> ConvertToPricing(this IQueryable<PolicytblPricingModelPricingSavedPricing> query)
        {
            var newQuery = from q in query
                           select new Pricing
                           {
                               PricingModelID = q.PricingModelID,
                               PolicyFaceAmount = q.FaceAmt.HasValue ? q.FaceAmt.Value : 0
                           };

            return newQuery;
        }

        public static IEnumerable<Pricing> ConvertToPricing(this IEnumerable<PolicytblPricingModelPricingSavedPricing> inList)
        {
            var newList = from l in inList
                           select new Pricing
                           {
                               PricingModelID = l.PricingModelID,
                               PolicyFaceAmount = l.FaceAmt.HasValue ? l.FaceAmt.Value : 0
                           };

            return newList.AsEnumerable();
        }

        public static Pricing ConvertToPricing(this PolicytblPricingModelPricingSavedPricing original)
        {
            if (original == null)
                return new Pricing();

            var newObject = new Pricing()
            {
                PricingModelID = original.PricingModelID,
                PolicyFaceAmount = original.FaceAmt.HasValue ? original.FaceAmt.Value : 0
            };

            return newObject;
        }
    }
}

Replace line #11 -  35 with the following:

public static IQueryable<Pricing> ConvertToPricing(this IQueryable<PolicytblPricingModelPricingSavedPricing> query)
        {
            var newQuery = from q in query
                           select q.ConvertToPricing();

            return newQuery;
        }

        public static IEnumerable<Pricing> ConvertToPricing(this IEnumerable<PolicytblPricingModelPricingSavedPricing> inList)
        {
            var newList = from l in inList
                          select l.ConvertToPricing();

            return newList.AsEnumerable();
        }

Thanks. That does do what we'd like to do. As a side note, we did switch to using Auto Mapper to take care of our mapping and that also abstracted out this particular piece.
