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();

How to get Bitcoin Private Key from an ExtPrivKey using NBitcoin

So, I am trying to send some money over using NBitcoin, there is a step where i am failing and that is creating de bitcoin secret to sign the transaction, I have the address, and the ExtPrivKey but i haven't gotten any luck signing it, any recommendation, this is my code below.
var priv = mbwallet.SelectedWallet.PrivateKeys[0].ToWif();
//var ool = new BitcoinSecret(base58, App.Network);
var privkey = mbwallet.SelectedWallet.PrivateKeys[0].PrivateKey.GetBitcoinSecret(App.Network).ToWif();
var key = Key.Parse(privkey, App.Network);
var keysT = key.GetWif(App.Network);
//var myaddress = mbwallet.SelectedWallet.PrivateKeys[0].PrivateKey.PubKey.GetAddress(App.Network);
var myaddress = mbwallet.SelectedWallet.CurrentAddress;
string address = Address.Text;
var destination = BitcoinAddress.Create(address, App.Network);
decimal value = Convert.ToDecimal(Value.Text);
var coins2 = GetCoins(value);
TransactionBuilder txBuilder = new TransactionBuilder();
var tx = txBuilder.AddCoins(coins2)
.AddKeys(keysT)
.SetChange(myaddress)
.Send(destination, new Money(value, MoneyUnit.BTC))
.SendFees("0.0002");
//.BuildTransaction(true);
var tx2 = txBuilder.BuildTransaction(true);
//Console.WriteLine(txBuilder.Verify(tx));
var hello = tx2.ToHex();
var txRepo = new NoSqlTransactionRepository();
//txRepo.Put(tx.GetHash(), tx);
//Assert(txBuilder.Verify(tx)); //check fully signed
List<ICoin> GetCoins(decimal sendAmount)
{
//var mbwallet = (root.DataContext as MainWindowViewModel);
var amountMoney = new Money(sendAmount, MoneyUnit.BTC);
var client = new QBitNinjaClient(App.Network);
var txInAmount = Money.Zero;
var coins1 = new List<ICoin>();
foreach (var balance in client.GetBalance(mbwallet.SelectedWallet.CurrentAddress,//MBWallet.Wallet.Address,
true).Result.Operations)
{
var transactionId = balance.TransactionId;
var transactionResponse =
client.GetTransaction(transactionId).Result;
var receivedCoins = transactionResponse.ReceivedCoins;
foreach (Coin coin in receivedCoins)
{
if (coin.TxOut.ScriptPubKey ==
mbwallet.SelectedWallet.CurrentAddress.ScriptPubKey)//MBWallet.Wallet.BitcoinPrivateKey.ScriptPubKey) // this may not be necessary
{
coins1.Add(coin);
txInAmount += (coin.Amount as Money);
}
}
}
return coins1;
}

For what I see in the code you already add the private key to the builder so basically you only need to sign , something like this
Transaction signed = txBuilder.SignTransaction(tx2);

app crashes before the request is sent to the server

I'm building an android app with Xamarin which communicates with an ASP.net server's API. I'm trying to upload a file to the server using the following lines of code:
public async Task<HttpResponseMessage> UploadFile(byte[] file)
{
var progress = new System.Net.Http.Handlers.ProgressMessageHandler();
//progress.HttpSendProgress += progress_HttpSendProgress;
using (var client = HttpClientFactory.Create(progress))
{
client.BaseAddress = new Uri(GlobalVariables.host);
// Set the Accept header for BSON.
client.DefaultRequestHeaders.Accept.Clear();
client.DefaultRequestHeaders.Accept.Add(
new MediaTypeWithQualityHeaderValue("application/bson"));
var request = new uploadFileModel { data = file, dateCreated = DateTime.Now, fileName = "myvideooo.mp4", username = "psyoptica" };
// POST using the BSON formatter.
MediaTypeFormatter bsonFormatter = new BsonMediaTypeFormatter();
var m = client.MaxResponseContentBufferSize;
var result = await client.PostAsync("api/media/upload", request, bsonFormatter);
return result.EnsureSuccessStatusCode();
}
}
The app crashes before the server receives the request. The file I'm trying to upload could be a video or an audio file. The server receives the request after the app has crashed. This works fine on the local server but the crash happens with the live server. My server side code looks like this:
[HttpPost]

What am I doing wrong here that's making the app crash. Is there a better way to do this?
Any help is appreciated.

Nested XML from list with needed data on multiple lines

I need to format an XML to a given hierarchy from a list (List<>). The list contains, for the banking information, data spread across multiple rows as shown in the image.
The XML output needs to be formatted like this:
<ROOT>
<DocumentElement>
<Supplier>
<Company>STV</Company>
<Code>000199</Code>
<Name>TrafTrans</Name>
<BankAccounts>
<SupplierBankAccount>
<Bban>220-012510-63</Bban>
<Name>B1</Name>
</SupplierBankAccount>
<SupplierBankAccount>
<Bban>RUIL</Bban>
<Name>RUIL</Name>
</SupplierBankAccount>
</BankAccounts>
<SupplierAddresses>
<SupplierAddress>
<Type>PostalAddress</Type>
<Name>Loc TrafTrans</Name>
<IsDefault>true</IsDefault>
<AddressParts>
<SupplierAddressPart>
<AddressPartKey>STREET_NAME</AddressPartKey>
<AddressPartText>Somewhere</AddressPartText>
</SupplierAddressPart>
<SupplierAddressPart>
<AddressPartKey>COUNTRY</AddressPartKey>
<AddressPartText>SPAIN</AddressPartText>
</SupplierAddressPart>
</AddressParts>
</SupplierAddress>
</SupplierAddresses>
</Supplier>
</DocumentElement>
</ROOT>
I already have a method that converts a list to an XML and returns a string. But the problem is that this only formats one item from the list and there could be additional info in the following items.
public static string SuppliersToXML(List<SupplierItem> supplier)
{
CultureInfo ci = new CultureInfo("en-US");
XmlDocument doc = new XmlDocument();
var root = doc.CreateElement("ROOT");
var rootNode = doc.AppendChild(root);
var docElem = doc.CreateElement("DocumentElement");
var docElemNode = rootNode.AppendChild(docElem);
foreach (var item in supplier)
{
var supplierElem = doc.CreateElement("Supplier");
var companyElem = (XmlNode)doc.CreateElement("Company");
companyElem.InnerText = item.Company.ToString();
//more code...
supplierElem.AppendChild(companyElem);
//more code...
}
return doc.OuterXml;
}

I have found the answer myself, it may not be the prettiest code ever written. But it does the job.
public static string SuppliersToXML(List<SupplierItem> supplier)
{
//A distinct select is needed because bank info can be on multiple lines. So first a list is generated with correct info except for bank information
List<SupplierItem> distinctsupplier = supplier
.GroupBy(p => p.Code)
.Select(g => g.First())
.ToList();
CultureInfo ci = new CultureInfo("en-US");
XmlDocument doc = new XmlDocument();
var root = doc.CreateElement("ROOT");
var rootNode = doc.AppendChild(root);
var docElem = doc.CreateElement("DocumentElement");
var docElemNode = rootNode.AppendChild(docElem);
foreach (var item in distinctsupplier)
{
var supplierElem = doc.CreateElement("Supplier");
var companyElem = (XmlNode)doc.CreateElement("Company");
companyElem.InnerText = item.Company.ToString();

//supplieraddress part
var supplierAddressesElem = doc.CreateElement("SupplierAddresses");
var supplierAddressElem = doc.CreateElement("SupplierAddress");
var supplierTypeValueElem = (XmlNode)doc.CreateElement("Type");

var bankAccountSupplElemNode = bankAccountElemNode.AppendChild(bankAccountSupplElem);

Lightswitch Updating() method not saving any data in DB

I am trying to save the entity data using General methods of lightswitch, which is Updating. Below is the following code. I am not able to figure out what I am missing. There is no error in the code or in the UI. Its just that nothing gets saved.
partial void viewFamilyProcessDatas_Updating(viewFamilyProcessData entity)
{
var AutoAddMissingListing = entity.AutoAddMissingListing;
var AutoAddOddLots = entity.AutoAddOddLots;
var DefaultFilterValue = entity.DefaultFilterValue;
var ExcludeZeroNumberOfUnits = entity.ExcludeZeroNumberOfUnits;
//objFamilyProcessData.FamilyID = entity.FamilyID;
var IgnoreForPricing = entity.IgnoreForPricing;
var LimitEndDate = entity.LimitEndDate;
var OffsetFromMaxAsAtDate = entity.OffsetFromMaxAsAtDate;
var PrefilterConstituents = entity.PrefilterConstituents;
var TimeDataExpires = entity.TimeDataExpires;
entity.AutoAddMissingListing = AutoAddMissingListing;
entity.AutoAddOddLots = AutoAddOddLots;
entity.DefaultFilterValue = DefaultFilterValue;
entity.ExcludeZeroNumberOfUnits = ExcludeZeroNumberOfUnits;
entity.IgnoreForPricing = IgnoreForPricing;
entity.LimitEndDate = LimitEndDate;
entity.OffsetFromMaxAsAtDate = OffsetFromMaxAsAtDate;
entity.PrefilterConstituents = PrefilterConstituents;
entity.TimeDataExpires = TimeDataExpires;
//this.DataWorkspace.SolaDBServerData.Details.DiscardChanges();
entity.Details.DiscardChanges();
}

The solution to this finally came to this:
partial void vwFamilyProcessDatas_Updating(vwFamilyProcessData entity)
{
if(entity.Details.EntityState.ToString() == "Modified")
{
var AutoAddMissingListing = entity.AutoAddMissingListing;
var AutoAddOddLots = entity.AutoAddOddLots;
var DefaultFilterValue = entity.DefaultFilterValue;
var ExcludeZeroNumberOfUnits = entity.ExcludeZeroNumberOfUnits;
var IgnoreForPricing = entity.IgnoreForPricing;
var LimitEndDate = entity.LimitEndDate;
var OffsetFromMaxAsAtDate = entity.OffsetFromMaxAsAtDate;
var PrefilterConstituents = entity.PrefilterConstituents;
var TimeDataExpires = entity.TimeDataExpires;
tblFamily objFamily = tblFamilies.Where(f => f.FamilyID == entity.FamilyID).Single();
objFamily.AutoAddMissingListing = AutoAddMissingListing;
objFamily.AutoAddOddLots = AutoAddOddLots;
objFamily.DefaultFilterValue = DefaultFilterValue;
objFamily.ExcludeZeroNumberOfUnits = ExcludeZeroNumberOfUnits;
objFamily.IgnoreForPricing = IgnoreForPricing;
objFamily.LimitEndDate = LimitEndDate;
objFamily.OffsetFromMaxAsAtDate = OffsetFromMaxAsAtDate;
objFamily.PrefilterConstituents = PrefilterConstituents;
objFamily.TimeDataExpires = TimeSpan.Parse(TimeDataExpires);
entity.Details.DiscardChanges();
}}
