how to return an object in c#?

I'm filling data inside an object with c# but I don't know how to return this object.
I create an object named ArasOrder and fill in the data and I want to return the ArasOrder object.
how can I do this.
public class ArasDeneme
{
public static void aras()
{
var ArasService = new ArasTEST.Service();
var ArasGonderi = new ArasTEST.ShippingOrder();
var ArasOrder = new ArasTEST.Order();
var parametreler = ArasKargoTEST.ParametreGet();
var newentegrationcode = "";
foreach (var item in parametreler)
{
var encode = entegrationcode();
var YeniGelenDesi = DesiHesabi(item.WebSiparisNo);
var yeniteminyeri = item.TeminYeri;
newentegrationcode = 123+ "" + encode;
ArasOrder.UserName = "";
ArasOrder.Password = "";
ArasOrder.ReceiverName = item.KargoAdSoyad;
ArasOrder.ReceiverPhone1 = item.KargoTelefon;
ArasOrder.ReceiverCityName = item.KargoIlAdi;
ArasOrder.ReceiverTownName = item.KargoIlceAdi;
ArasOrder.ReceiverAddress = item.KargoAdres;
ArasOrder.TradingWaybillNumber = item.WebSiparisNo;
ArasOrder.PieceCount = "1";
ArasOrder.IntegrationCode = newentegrationcode;
ArasOrder.PayorTypeCode = "1";
ArasOrder.IsWorldWide = "0";
ArasOrder.IsCod = "0";
ArasOrder.VolumetricWeight = YeniGelenDesi;
ArasOrder.SenderAccountAddressId = "1071";
ArasTEST.PieceDetail[] ArasPieceDetails = new ArasTEST.PieceDetail[1];
PieceDetail ArasPieceDetail1 = new PieceDetail();
ArasPieceDetail1.BarcodeNumber = newentegrationcode;
ArasPieceDetail1.VolumetricWeight = YeniGelenDesi;
ArasPieceDetail1.Weight = "1";
ArasPieceDetail1.Description = "";
ArasPieceDetails[0] = ArasPieceDetail1;
ArasOrder.PieceDetails = ArasPieceDetails;
var ArasOrderInfo = new ArasTEST.Order[1];
ArasOrderInfo[0] = ArasOrder;
var takipNoResult = ArasService.SetOrder("", "", "");
var ArasOrderResultInfo = takipNoResult[0];
var SonucKodu = takipNoResult[0].ResultCode;
var SonucMesaji = takipNoResult[0].ResultMessage;
var SonucInvoiceKey = takipNoResult[0].InvoiceKey;
}
}
}

You should define the return type and return the instance.
public static ArasTEST aras()
{
// insert code here...
return ArasOrder;
}

Change void to ArasDeneme return type.
Then call like:
var ad = ArasDeneme.aras();

Entity Framework 5 will not allow .SaveChanges

I've upgraded to Entity Framework 5 and the .SaveChanges is no longer available.
How do we save our changes?
When ever I do a db.SaveChanges(); it errors because .SaveChanges is not there.
static bool Insert(Elevation elevation, out Elevation elevationOUT)
{
using (var db = new StorefrontSystemEntities())
{
//erik#afbs.net : DA91DC34-FA29-4ABD-BCC0-D04408310E3E
//projectID = 12
elevationOUT = null;
var projs = from p in db.Projects
where p.ID == elevation.ProjectID
select p;
//
var proj = projs.SingleOrDefault();
if (proj == null) { return false; }
//Elevation
var elev = new Elevation
{
ID = proj.ID,
Name = elevation.Name,
Note = elevation.Note,
ComponentID = elevation.CompID,
VerCutHD = elevation.VerCutHD,
VerCutSill = elevation.VerCutSill,
Created = DateTime.Now
};
proj.Elevations.Add(elev);
//Bays
foreach (var bay in elevation.Bays)
{
var b = new Bay
{
Position = bay.Position,
IsBulkhead = bay.IsBulkhead,
Note = bay.Note,
Size = GetClientSize(bay.Size),
IsFixed = bay.IsFixed,
Finish = GetClientFinish(bay.Finish),
Siteline = GetClientSiteline(bay.Siteline, elev.ComponentID),
VerCutHD = elevation.VerCutHD,
VerCutSill = elevation.VerCutSill
//
};
elev.Bays.Add(b);
};
db.SaveChanges();
elevationOUT = elev;
elevationOUT.IsGeneric = proj.GenericCatalogID > 0;
}
return true;
}

Cannot implicitly convert type but already it's Converted

Cannot implicitly convert type problem.but in here it's converted & assign.Can anyone tell me whats wrong here ? here i have post whole code for it.
[HttpGet]
public ActionResult AddProduct(int? id)
{
Models.ProductsModels.Products product = new Models.ProductsModels.Products();
ViewBag.ListOfCategories = new SelectList(_cat.GetCategory(), "CategoryId", "CategoryName");
ViewBag.ListOfBrands = new SelectList(_brad.GetAllBrands(), "BrandId", "BrandName");
int productId = id ?? 0;
if (id.HasValue)
{
ICS.Data.Product _prod = new ICS.Data.Product();
product = (new ProductController()).GetProductById(productId);
product.ProductId = _prod.ProductId;
product.ProductName = _prod.ProductName;
product.CategoryId = _prod.Category_CategoryId;
product.BrandId = _prod.Brand_BrandId;
product.PriceSettings = _prod.IsFixed;
product.PurchasePrice = (float)_prod.PurchasePrice;
product.ItemPrice = (float)_prod.ItemPrice;
product.Vat = (double)_prod.Vat;
product.WholeSalePrice = (float)_prod.WholeSalePrice;
product.RetailPrice = (float)_prod.RetailPrice;
product.Comments = _prod.Comments;
}
return View(product);
}
finally it's retun to the Product View.

Change this in your code:
_prod = (new ProductController()).GetProductById(productId);
Full code:
[HttpGet]
public ActionResult AddProduct(int? id)
{
Models.ProductsModels.Products product = new Models.ProductsModels.Products();
ViewBag.ListOfCategories = new SelectList(_cat.GetCategory(), "CategoryId", "CategoryName");
ViewBag.ListOfBrands = new SelectList(_brad.GetAllBrands(), "BrandId", "BrandName");
int productId = id ?? 0;
if (id.HasValue)
{
ICS.Data.Product _prod = (new ProductController()).GetProductById(productId);
product.ProductId = _prod.ProductId;
product.ProductName = _prod.ProductName;
product.CategoryId = _prod.Category_CategoryId;
product.BrandId = _prod.Brand_BrandId;
product.PriceSettings = _prod.IsFixed;
product.PurchasePrice = (float)_prod.PurchasePrice;
product.ItemPrice = (float)_prod.ItemPrice;
product.Vat = (double)_prod.Vat;
product.WholeSalePrice = (float)_prod.WholeSalePrice;
product.RetailPrice = (float)_prod.RetailPrice;
product.Comments = _prod.Comments;
}
return View(product);
}

Multiple Array Insertion in C# using Foreach statement

private void Updated_ModRecFGA()
{
try
{
DRFGAModifiedRecord TABLE = new DRFGAModifiedRecord();
foreach (ArrayFunc Row in ArrayFunc.QueryResult)
{
foreach (ArrayFunc Row2 in ArrayFunc.QueryResult1)
{
TABLE.RecordDocID = Row.FGACol1;
TABLE.DRNo = Row.FGACol2;
TABLE.DDNum = Row.FGACol3;
TABLE.LineNumber = Row.FGACol4;
TABLE.Itemnmbr = Row2.updItemCode;
TABLE.Itemdesc = Row2.updItemDesc;
TABLE.Pallet = Row2.updPallets;
TABLE.BagsNo = Row2.updBagsNo;
TABLE.TotalLoaded = Row2.updTotalKgs;
TABLE.PostStat = Row2.updPostStat;
TABLE.ProdCode = Row2.updProdcode;
TABLE.VariantCode = Row2.updVariantCode;
TABLE.DateModify = DateTime.Now.ToShortDateString();
TABLE.TimeModify = DateTime.Now.ToShortTimeString();
TABLE.UserModify = "Mik";//GlobalvarClass.LogUser;
TABLE.ReasonModify = GlobalvarClass.GetModReasOnDR;
TABLE.FileType = "New";
saveREC(TABLE);
gfunc.MsgBox("Saved", 1);
}
}
ArrayFunc.QueryResult.Clear();
ArrayFunc.QueryResult1.Clear();
GlobalvarClass.GetModReasOnDR = string.Empty;
}
catch (Exception ex) { MessageBox.Show(ex.Message.ToString()); }
}
Is there another proper way to use this kind of code something like this to avoid duplicate? I know it duplicate because of two foreach statement

Just combine the two using linq. Remember to include using System.Linq; in your using clause.
var results = ArrayFunc.QueryResult.SelectMany(l1 => ArrayFunc.QueryResult1, (l1, l2) =>
new DRFGAModifiedRecord
{
RecordDocID = l1.FGACol1,
DRNo = l1.FGACol2,
DDNum = l1.FGACol3,
LineNumber = l1.FGACol4,
Itemnmbr = l2.updItemCode,
Itemdesc = l2.updItemDesc,
Pallet = l2.updPallets,
BagsNo = l2.updBagsNo,
TotalLoaded = l2.updTotalKgs,
PostStat = l2.updPostStat,
ProdCode = l2.updProdcode,
VariantCode = l2.updVariantCode,
DateModify = DateTime.Now.ToShortDateString(),
TimeModify = DateTime.Now.ToShortTimeString(),
UserModify = "Mik",//GlobalvarClass.LogUser
ReasonModify = GlobalvarClass.GetModReasOnDR,
FileType = "New"
}).ToList();
foreach (row in results)
{
saveREC(row);
gfunc.MsgBox("Saved", 1);
}
Alternatively you can do it with a query expression:
var result = (from l1 in ArrayFunc.QueryResult
from l2 in ArrayFunc.QueryResult1
select new DRFGAModifiedRecord { RecordDocID = l1.FGACol1 ... }).ToList();

IQueryable, converting Anonymous Type to Strong Type

Is there a more elegant/concise way of this; I'd like to get rid of foreach loop with the WorkListItem initialization code.
var queryable = registrations.Select(
r => new
{
r.Id, r.AccountNumber, r.DateAdded, r.DateUpdated, r.Patient, r.Patient.InsuranceInfos
});
var list = queryable.ToList();
var workListItems = new List<WorkListItem>();
foreach (var anonymous in list)
{
var w = new WorkListItem
{
Id = anonymous.Id,
ClientAccountId = anonymous.AccountNumber,
DateAdded = anonymous.DateAdded,
DateUpdated = anonymous.DateUpdated,
Patient = anonymous.Patient,
InsuraceInfos = anonymous.Patient.InsuranceInfos
};
workListItems.Add(w);
}
return workListItems;

Yes you can completely cut out the "middle-man" as it were and select straight into a new WorkListItem as below:
var list = registrations.Select(r => new WorkListItem
{
Id = r.Id,
ClientAccountId = r.AccountNumber,
DateAdded = r.DateAdded,
DateUpdated = r.DateUpdated,
Patient = r.Patient,
InsuraceInfos = r.Patient.InsuranceInfos
}).ToList();
