How do I delete a blob after it has been read by my function

I have created a blob triggered Azure function App that takes data from a TSV file and splits it up and writes data to a SQL database.
after the file have been read I would like to delete it from the blob container.
I'm currently studying and this is my first C# code ever so I hope you can help me out and be specific.
I have looked at the documentation for
CloudBlockBlob blob = CloudBlobContainer.GetBlockBlobReference(???????);
blob.DeleteIfExists();
but I can't seem to find out what to put here
here is my complete function. please if you could help me out where to insert the delete command as well I would appreciate it :)

the reason I want to delete the blob after is because the function reads the file more than once. when it does I get a timeout because it takes more than 5 mins to process data. may be that's why it starts more than once.
is there a way to write this so the process is quicker?
the TSV files can hold up to 100.000 lines sometime.
looking forward to some advise on this
Robin

If you look at the MSFT API for GetBlockBlobReference method it takes in a blobName as a parameter.
So ideally you already have the name from the param on your function. You can just do
CloudBlockBlob blob = CloudBlobContainer.GetBlockBlobReference(name);
blob.DeleteIfExists();

SaveChanges() doesn't insert any records to database

I'm using Entity Framework to add new records to the database, everything goes ok without any errors, but I don't see the new record in the database.
Update code works, but insert code doesn't work. No errors appear, but no records are inserted into the database.
My code :
var DBs2 = ConnectionTools.OpenConn();
DBs2.Configuration.AutoDetectChangesEnabled = false;
DBs2.Configuration.ValidateOnSaveEnabled = false;
var resList = CreatedSerials.Where(u => u.Item4 == VID).ToList();
foreach (var r in resList)
{
// if serial id ==0 => new then add it as new
if ( r.Item7 == 0)
{
try
{
var purchasesItemSerials = new purchases_item_seriels()
{
pitem_ID = pitem_ID,
stitems_ID = r.Item1,
pmain_ID = PurchasesID,
pitem_virtualID = r.Item4,
pis_CustomSerial = r.Item2,
pis_ExpireDate = r.Item3,
pis_Statues = 0,
ss_StoreID = Convert.ToInt32(gridView1.GetRowCellValue(ItemImdex, "storeID")),
Purchases_Price = Convert.ToDecimal(gridView1.GetRowCellValue(ItemImdex, "item_NetSmallestUnitPrice")),
};
ss.Add(purchasesItemSerials);
}
catch (Exception eeeeee)
{
Msg.Show("", eeeeee.ToString(), 0);return;
}
}
else
{
var DBs350 = ConnectionTools.OpenConn();
var UpdateSerial = DBs350.purchases_item_seriels.Find(r.Item7);
UpdateSerial.pitem_ID = pitem_ID;
UpdateSerial.stitems_ID = r.Item1;
UpdateSerial. pmain_ID = PurchasesID;
UpdateSerial.pitem_virtualID = r.Item4;
UpdateSerial.pis_CustomSerial = r.Item2;
UpdateSerial.pis_ExpireDate = r.Item3;
UpdateSerial.pis_Statues = r.Item6;
UpdateSerial.ss_StoreID = Convert.ToInt32(gridView1.GetRowCellValue(ItemImdex, "storeID"));
UpdateSerial.Purchases_Price = Convert.ToDecimal(gridView1.GetRowCellValue(ItemImdex, "item_NetSmallestUnitPrice"));
DBs350.SaveChanges();
}
}
try
{
DBs2.purchases_item_seriels.AddRange(ss);
DBs2.SaveChanges();
}
catch (Exception eeeeee)
{
Msg.Show("", eeeeee.ToString(), 0);return;
}
I also tried :
DBs2.Configuration.AutoDetectChangesEnabled = true;
DBs2.Configuration.ValidateOnSaveEnabled = true;
but again: no data is inserted, no errors appear
I also tried :
int returnCode = DBs2.SaveChanges();
and returnCode = 0
**I also tried : inserting just a single item then SaveChanges **
// if this serial is new
var NewSerialresList = CreatedSerials.Where(u => u.Item4 == VID && u.Item7 == 0).ToList();
if (NewSerialresList.Count() > 0)
{
var ss = new List<purchases_item_seriels>();
foreach (var r in NewSerialresList)
{
try
{
mrsalesdbEntities DBs002 = new mrsalesdbEntities();
var purchasesItemSerials = new purchases_item_seriels()
{
pitem_ID = pitem_ID,
stitems_ID = r.Item1,
pmain_ID = PurchasesID,
pitem_virtualID = r.Item4,
pis_CustomSerial = r.Item2,
pis_ExpireDate = r.Item3,
pis_Statues = 0,
ss_StoreID = Convert.ToInt32(gridView1.GetRowCellValue(ItemImdex, "storeID")),
Purchases_Price = Convert.ToDecimal(gridView1.GetRowCellValue(ItemImdex, "item_NetSmallestUnitPrice")),
};
//ss.Add(purchasesItemSerials);
DBs002.purchases_item_seriels.Add(purchasesItemSerials);
DBs002.SaveChanges();
}
catch (Exception ex)
{
Msg.Show("", ex.ToString(), 0);
}
}
int CC = ss.Count();
}

C# Authorize.net Create Profile Issue

The following code is charging the card, however it is not creating the profile....any tips? I'm assuming I'm missing something, or using the wrong Type...
var opaqueData = new opaqueDataType { dataDescriptor = "COMMON.ACCEPT.INAPP.PAYMENT", dataValue = paymentNonce };
//standard api call to retrieve response
var paymentType = new paymentType { Item = opaqueData };
var transactionRequest = new transactionRequestType
{
transactionType = transactionTypeEnum.authCaptureTransaction.ToString(), // authorize and capture transaction
amount = paymentAmount,
payment = paymentType,
customer = new customerDataType()
{
type = customerTypeEnum.individual,
id = userID.ToString()
},
profile = new customerProfilePaymentType()
{
createProfile = true
}
};
var request = new createTransactionRequest { transactionRequest = transactionRequest };
// instantiate the contoller that will call the service
var controller = new createTransactionController(request);
const SslProtocols _Tls12 = (SslProtocols)0x00000C00;
const SecurityProtocolType Tls12 = (SecurityProtocolType)_Tls12;
ServicePointManager.SecurityProtocol = Tls12;
controller.Execute();
// get the response from the service (errors contained if any)
var response = controller.GetApiResponse();
UPDATE:
Since apparently OpaqueData is not allowed, I changed it to make the profile manually. I am getting the following Error: "Error: I00001 Successful."
// Add Payment method to Customer.
customerPaymentProfileType opaquePaymentProfile = new customerPaymentProfileType();
opaquePaymentProfile.payment = paymentType;
opaquePaymentProfile.customerType = customerTypeEnum.individual;
var request2 = new createCustomerPaymentProfileRequest
{
paymentProfile = opaquePaymentProfile,
validationMode = validationModeEnum.none,
customerProfileId = userID.ToString()
};
var controller2 = new createCustomerPaymentProfileController(request2);
controller2.Execute();
//Send Request to EndPoint
createCustomerPaymentProfileResponse response2 = controller2.GetApiResponse();
if (response2 != null && response2.messages.resultCode == messageTypeEnum.Ok)
{
if (response2 != null && response2.messages.message != null)
{
//Console.WriteLine("Success, createCustomerPaymentProfileID : " + response.customerPaymentProfileId);

Update #2
Very confused as auth.net documentation says this code means success...so why don't I see the CIM payment method created??? RESPONSE CODE DOCS
Update #3
So I was printing out the main response message instead of the CIM request message, duh. The actual error was: "E00114 Invalid OTS Token."
Based on the the documentation, that error is usually from a used Key, so I am now generating 2 keys (One to process and One to store via CIM) but am now getting this error: "E00040 The record cannot be found."....Any ideas?

So the answer to this question is:
You can not auto create a payment profile using opaque card data, so the answer is to make it manually once you have a successful charge.
You can not use the same opaque card data to charge and store, as they are one time use, so for my web method I ended up passing 2 opaque data keys.
You have to make different calls for setting up a brand new customer and an existing customer just adding a new card. I have pasted an excerpt of my end solution below:
ApiOperationBase<ANetApiRequest, ANetApiResponse>.RunEnvironment = (System.Configuration.ConfigurationManager.AppSettings["Authorize-Live"].ToUpper() == "TRUE" ? AuthorizeNet.Environment.PRODUCTION : AuthorizeNet.Environment.SANDBOX);

ItemElementName = ItemChoiceType.transactionKey,
Item = (System.Configuration.ConfigurationManager.AppSettings["Authorize-Live"].ToUpper() == "TRUE" ? System.Configuration.ConfigurationManager.AppSettings["Authorize-TransactionKey"] : System.Configuration.ConfigurationManager.AppSettings["Authorize-TransactionKey-SandBox"])

you are not attaching the card with the customer. You have created the card object but not attached with the customer. Follow this syntax to add the card
var myCustomer = new StripeCustomerCreateOptions();
myCustomer.Email = "pork#email.com";
myCustomer.Description = "Johnny Tenderloin (pork#email.com)";
// setting up the card
myCustomer.SourceCard = new SourceCard()
{
Number = "4242424242424242",
ExpirationYear = "2022",
ExpirationMonth = "10",
Cvc = "1223" // optional
};
myCustomer.PlanId = *planId*; // only if you have a plan
myCustomer.TaxPercent = 20; // only if you are passing a plan, this tax percent will be added to the price.
myCustomer.Coupon = *couponId*; // only if you have a coupon
myCustomer.TrialEnd = DateTime.UtcNow.AddMonths(1); // when the customers trial ends (overrides the plan if applicable)
myCustomer.Quantity = 1; // optional, defaults to 1
var customerService = new StripeCustomerService();
StripeCustomer stripeCustomer = customerService.Create(myCustomer)

C# Memory management (Memory leak?)

I am working on a program in WPF that basically retrieves JSON data from a WEB API and parses it then saves it to database with EF.
The problem is the memory usage of the program keeps on increasing as the time goes by. (From 20MB to 2gigs).
The following is the code that I am using.
Is there any optimization i can perform to keep the memory under a limit and say the unused objects gets deleted periodically.

DataConnection context keeps tracking all objects that it ever saw. Put creation of dc inside the loop and dispose it every time. You don't need the context after each SaveChanges is called.
