Combining results from two classes

Question

In this method below I am working out a products code(StockItem):

    var qisg = new QuoteItemSectionGroup
    {
        SectionGroup = db.SectionGroups.Where(x => x.Name == "Longitudinals" && x.Section == TruckSection.Floor).First(),
        StockItem = quoteItem.BodyType.Longitudinal, <<--------
        Quantity = 2,
        Length = globals.FloorCalculatedLength
    };

I have two classes called: BodyType & Chassis. Both has a column called Longitudinal.

In my method above I have worked out the BodyType.Longitudinal and = it to my StockItem.

StockItem = quoteItem.BodyType.Longitudinal,

The problem is that I have to set the second class Chassis.Longitudinal = to my StockItem aswell at the same time.

StockItem = quoteItem.Chassis.Longitudinal,

Example:

StockItem = quoteItem.BodyType.Longitudinal + quoteItem.Chassis.Longitudinal,

Is there a way to do this? I am just showing the example, because I have no idea how to do this.

EDIT: This is where I set the code for each StockItem

BodyType

context.BodyTypes.AddOrUpdate<BodyType>(x => x.Name,
    new BodyType { Name = "Corrugated", isFlatDeck = false, LongitudinalId = context.StockItems.Where(x => x.StockCode == "SCH105").First().Id });

Chassis

context.Chassis.AddOrUpdate<Chassis>(x => x.Name,
    new Chassis { Name = "DAIHATSU DELTA V116", LongitudinalId = context.StockItems.Where(x => x.StockCode == "SCH100").First().Id });

Answer 1

As far as I understand what you are trying to achieve, can't be done without changing the QuoteItemSectionGroup class.

You should modify the StockItem into something like may be dictionary.

StockItem<string, string>;  // You can decide on the data type.

And then fill data somewhat like this.

    var qisg = new QuoteItemSectionGroup
        {
            SectionGroup = db.SectionGroups.Where(x => x.Name == "Longitudinals" && x.Section == TruckSection.Floor).First(),
            StockItem.Add('BodyType.Longitudinal',quoteItem.BodyType.Longitudinal);
            StockItem.Add('Chassis.Longitudinal',quoteItem.Chassis.Longitudinal); <<--------
            Quantity = 2,
            Length = globals.FloorCalculatedLength
        };
