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();
}
i use this function to change the connection variables at run-time :

/* this would be used if the
* connectionString name varied from
* the base EF class name */
{
try
{
// use the const name if it's not null, otherwise
// using the convention of connection string = EF contextname
// grab the type name and we're done
var configNameEf = string.IsNullOrEmpty(configConnectionStringName)

// add a reference to System.Configuration
var entityCnxStringBuilder = new EntityConnectionStringBuilder

System.OutOfMemoryExeption C#

When I'm running my application and load a file(25MB) through it, everything runs just fine.
But when I try loading a file(160MB) I get a System.OutOfMemoryExeption.
Although I have been able to load the larger file at some point in time.
Is there anyway to fix this? If so, any help would be much appreciated!
My Code that loads the files:

textBoxResStart_Status3,

};

Given the comments, it sounds like the problem is really that you're using structs extensively. These should almost certainly be classes for idiomatic C#. See the design guidelines for more details of how to pick between these.
At the moment, you're loading all the values in a big List<T>. Internally, that has an array - so it's going to be an array of your struct type. That means all the values are required to be in a single contiguous chunk of memory - and it sounds like that chunk can't be allocated.
If you change your data types to classes, then a contiguous chunk of memory will still be required - but only enough to store references to the objects you create. You'll end up using slightly more data overall (due to per-object overhead and the references to those objects) but you won't have nearly as strict a requirement on allocating a single big chunk of memory.
That's only one reason to use classes here - the reason of "this just isn't a normal use of structs" is a far bigger one, IMO.
As an aside, I'd also very strongly recommend that you start following .NET naming conventions, particularly around the use of capitalization and avoiding underscores to separate words in names. (There are other suggestions for improving the code in the question too, and I'd advise reading them all carefully.)

Entity saves ok but will not update record no matter what I do

Context is not saving to the database no matter what i do it will insert a new record fine but not save. This is using sql server and the user had permissions ot update data have already checked this
private void btnOk_Click(object sender, EventArgs e)
{
SourceContext SourceDal = new SourceContext();
Appointment _appointment = new Appointment();
int errorCount = 0;
Patient _patient = new Patient();
_patient = SourceDal.getPatientByPatientId(txtPatientId.Text);
_patient.SSN = txtSSN.Text;
_patient.FirstName = txtPatientFirstName.Text;
_patient.LastName = txtPatientLastName.Text;
_patient.Middle = txtPatientMiddle.Text;
_patient.AddressOne = txtPatientAddressOne.Text;
_patient.City = txtPatientCity.Text;
_patient.State = txtPatientState.Text;
_patient.ZipCode = txtPatientZip.Text;
_patient.HomePhone = txtPatientHomePhone.Text;
_patient.WorkPhone = txtPatientWorkPhone.Text;
_patient.CellPhone = txtPatientCellPhone.Text;
if (rBtnHomePhone.Checked == true)
_patient.ApptPhone = txtPatientHomePhone.Text;
if (rBtnHomePhone.Checked == true)
_patient.ApptPhone = txtPatientHomePhone.Text;
if (rBtnWorkPhone.Checked == true)
_patient.ApptPhone = txtPatientWorkPhone.Text;
_patient.BirthDate = dtBirthDate.DateTime;
_patient.emailAddress = txtPatientEmail.Text;
_patient.Race = (int)dpRace.SelectedValue;
_patient.Ethnicity = (int)dpEthnicity.SelectedValue;
_patient.Language = (int)dpLanguages.SelectedValue;
_patient.AlertNote = txtPatientNotes.Text;
if (dpGender.Text == "")
{
dpGender.Focus();
errorCount = 1;
lblGenderRequired.Text = "* Gender is required.";
}
else
{
errorCount = 0;
lblGenderRequired.Visible = false;
}
_patient.Gender = dpGender.Text.Substring(0, 1);
_patient.PatientID = txtPatientId.Text;
txtPatientFirstName.Text = _patient.FirstName;
txtPatientLastName.Text = _patient.LastName;
// IF ITS SAVE NEW GO AHEAD ADD IT TO THE CONTEXT.
SourceDal.AddToPatient(_patient);
}
Add to paitent has the following
public void AddToPatient(Patient newPatient)
{
using (var myContext = new SMBASchedulerEntities(this.Connectionstring))
{
myContext.Patients.Add(newPatient);
if (newPatient.ID == 0)
{
myContext.Entry(newPatient).State = EntityState.Added;
}
else
{
myContext.Entry(newPatient).State = EntityState.Modified;
}
try
{
myContext.SaveChanges();
}
catch (DbEntityValidationException ex)
{
foreach (var entityValidationErrors in ex.EntityValidationErrors)
{
foreach (var validationError in entityValidationErrors.ValidationErrors)
{
Console.Write("Property: " + validationError.PropertyName + " Error: " + validationError.ErrorMessage);
}
}
}
}
}
It adds in the record fine but it just wont save the current record no matter what i do even though all the details are correct. But when i reload the form and the application the update is not there the email address is not saved no are any the other updates.

I suspect I'm not familiar with that entity framework, as I'm unfamiliar with the some of that syntax, but you should be able to use something like this:
public void AddToPatient(Patient newPatient)
{
SMBASchedulerEntities dbContext = new SMBASchedulerEntities();
if (newPatient.ID.ToString() != "0")
{//Update the record
Patient updatePatient = dbContext.Patients.Single(p => p.ID == newPatient.ID);
updatePatient.FirstName = newPatient.FirstName;
updatePatient.LastName = newPatient.LastName;
...
...
dbContext.SubmitChanges();
}
else
{//Insert a new record
Patient insertPatient = new Patient();
insertPatient.FirstName = newPatient.FirstName;
insertPatient.LastName = newPatient.LastName;
...
...
dbContext.Patients.InsertOnSubmit(insertPatient);
dbContext.SubmitChanges();
}
}
To put this another way, check to see if you need to insert or update a new patient first, before inserting it every time.

Async function in Converting object to another object in c#

I would like to implement an async function in converting the object to another object then in saving to the database.
public List<Order> GetOrdersFromTradeGeckoCount()
{
string orderLimit = base.StorePlugin.Store.OrderLimit.HasValue ? base.StorePlugin.Store.OrderLimit.Value.ToString() : "250";
string filters = string.Format("?status=finalized&limit={0}", orderLimit);
HttpResponseMessage response = _requestHelper.GetHttpResponse("orders" + filters);
var tgOrders = GetOrdersResponse(response);
//Async Convert and Save Order
ConvertToORouterOrdersAsync(tgOrders);
return ConvertToORouterOrdersCount(tgOrders);
}
I would like this method ConvertToORouterOrdersAsync(tgOrders); will run in the background and will return the Count of Orders from this ConvertToORouterOrdersCount(tgOrders) before the conversion is done.
Please help me to change the implementation to asynchronous.
public async void ConvertToORouterOrdersAsync(List<TGOrder> tgOrders)
{
var orderMgr = new OrderDAC();
var orders = new List<Order>(tgOrders.Count());
foreach (TGOrder tgOrder in tgOrders)
{
try
{
var order = new Order();
var orderId = TryConvertInt64(CleanUpOrderId(tgOrder.order_number));
if (orderId == null) continue;
var tempOrderId = string.Format("{0}{1}", base.StoreId, orderId.Value);
order.OrderId = TryConvertInt64(tempOrderId).Value;
order.StoreOrderId = tgOrder.id.ToString();
order.WarehouseOrderId = tgOrder.order_number;
var orderFromDb = orderMgr.GetOrder(order.OrderId, base.StoreId);
if (orderFromDb != null) continue; // make sure we only import new order(i.e. doesn't exists in database)
// shipping address
var tgShippingAddress = GetAddress(tgOrder.shipping_address_id);
if (tgShippingAddress == null) continue;
order.ShipFirstName = tgShippingAddress.first_name;
order.ShipLastName = tgShippingAddress.last_name;
order.ShipCompanyName = tgShippingAddress.company_name;
order.ShipAddress1 = tgShippingAddress.address1;
order.ShipAddress2 = tgShippingAddress.address2;
order.ShipCity = tgShippingAddress.suburb;
order.ShipState = tgShippingAddress.state;
order.ShipPostalCode = tgShippingAddress.zip_code;
order.ShipCountry = tgShippingAddress.country;
order.ShipPhoneNumber = tgShippingAddress.phone_number;
order.CustomerEmail = tgOrder.email;
// billing address
var tgBillingAddress = GetAddress(tgOrder.billing_address_id);
if (tgBillingAddress == null) continue;
// line items
var lineItems = GetOrderLineItems(tgOrder.id);
foreach (TGOrderLineItem lineItem in lineItems)
{
var ol = new OrderLine();
if (lineItem.variant_id.HasValue)
{
var variant = GetVariant(lineItem.variant_id.Value);
if (variant == null) continue;
ol.ProductName = variant.product_name;
ol.SKU = variant.sku;
ol.ThreePLSKU = ol.SKU;
ol.Qty = Convert.ToInt16(TryGetDecimal(lineItem.quantity));
ol.OrderId = order.OrderId;
ol.Price = TryGetDecimal(lineItem.price);
ol.SubTotal = (ol.Qty * ol.Price);
ol.StoreOrderLineId = Convert.ToString(lineItem.id);
order.OrderLines.Add(ol);
}
}
var validator = new Validator(base.Task);
if (validator.IsValidOrder(order))
{
orderMgr.Add(order);
}
}
catch (Exception ex)
{
AppendError(ex.Message);
}
}
}

To really have a advantage of the async and await the underlying calls should have async versions, for example the database calls should be async, don't know if you use EF or just plain SqlCommand but both have async versions of their calls.
Other calls that can be async is HTTP calls.
I have edited youre code with the assumption you are able to convert the underlying code to async.
public async Task<List<Order> GetOrdersFromTradeGeckoCount()
{
string orderLimit = base.StorePlugin.Store.OrderLimit.HasValue ? base.StorePlugin.Store.OrderLimit.Value.ToString() : "250";
string filters = string.Format("?status=finalized&limit={0}", orderLimit);
HttpResponseMessage response = await _requestHelper.GetHttpResponseAsync("orders" + filters).ConfigureAwait(false);
var tgOrders = GetOrdersResponse(response);
//Async Convert and Save Order
await ConvertToORouterOrdersAsync(tgOrders).ConfigureAwait(false);
return await ConvertToORouterOrdersCountAsync(tgOrders).ConfigureAwait(false);
}
public async Task ConvertToORouterOrdersAsync(List<TGOrder> tgOrders)
{
var orderMgr = new OrderDAC();
var orders = new List<Order>(tgOrders.Count());
foreach (TGOrder tgOrder in tgOrders)
{
try
{
var order = new Order();
var orderId = TryConvertInt64(CleanUpOrderId(tgOrder.order_number));
if (orderId == null) continue;
var tempOrderId = string.Format("{0}{1}", base.StoreId, orderId.Value);
order.OrderId = TryConvertInt64(tempOrderId).Value;
order.StoreOrderId = tgOrder.id.ToString();
order.WarehouseOrderId = tgOrder.order_number;
var orderFromDb = await orderMgr.GetOrderAsync(order.OrderId, base.StoreId).ConfigureAwait(false);
if (orderFromDb != null) continue; // make sure we only import new order(i.e. doesn't exists in database)
// shipping address
var tgShippingAddress = GetAddress(tgOrder.shipping_address_id);
if (tgShippingAddress == null) continue;
order.ShipFirstName = tgShippingAddress.first_name;
order.ShipLastName = tgShippingAddress.last_name;
order.ShipCompanyName = tgShippingAddress.company_name;
order.ShipAddress1 = tgShippingAddress.address1;
order.ShipAddress2 = tgShippingAddress.address2;
order.ShipCity = tgShippingAddress.suburb;
order.ShipState = tgShippingAddress.state;
order.ShipPostalCode = tgShippingAddress.zip_code;
order.ShipCountry = tgShippingAddress.country;
order.ShipPhoneNumber = tgShippingAddress.phone_number;
order.CustomerEmail = tgOrder.email;
// billing address
var tgBillingAddress = GetAddress(tgOrder.billing_address_id);
if (tgBillingAddress == null) continue;
// line items
var lineItems = GetOrderLineItems(tgOrder.id);
foreach (TGOrderLineItem lineItem in lineItems)
{
var ol = new OrderLine();
if (lineItem.variant_id.HasValue)
{
var variant = GetVariant(lineItem.variant_id.Value);
if (variant == null) continue;
ol.ProductName = variant.product_name;
ol.SKU = variant.sku;
ol.ThreePLSKU = ol.SKU;
ol.Qty = Convert.ToInt16(TryGetDecimal(lineItem.quantity));
ol.OrderId = order.OrderId;
ol.Price = TryGetDecimal(lineItem.price);
ol.SubTotal = (ol.Qty * ol.Price);
ol.StoreOrderLineId = Convert.ToString(lineItem.id);
order.OrderLines.Add(ol);
}
}
var validator = new Validator(base.Task);
if (validator.IsValidOrder(order))
{
await orderMgr.AddAsync(order).ConfigureAwait(false);
}
}
catch (Exception ex)
{
AppendError(ex.Message);
}
}
}
Or if you just want to run the code in the background you can also just wrap it in a Task.Run
public async Task<List<Order> GetOrdersFromTradeGeckoCount()
{
string orderLimit = base.StorePlugin.Store.OrderLimit.HasValue ? base.StorePlugin.Store.OrderLimit.Value.ToString() : "250";
string filters = string.Format("?status=finalized&limit={0}", orderLimit);
HttpResponseMessage response = _requestHelper.GetHttpResponse("orders" + filters);
var tgOrders = GetOrdersResponse(response);
//Async Convert and Save Order
await ConvertToORouterOrdersAsync(tgOrders).ConfigureAwait(false);
return ConvertToORouterOrdersCount(tgOrders);
}
public Task ConvertToORouterOrdersAsync(List<TGOrder> tgOrders)
{
return Task.Run(() =>
{
var orderMgr = new OrderDAC();
var orders = new List<Order>(tgOrders.Count());
foreach (TGOrder tgOrder in tgOrders)
{
try
{
var order = new Order();
var orderId = TryConvertInt64(CleanUpOrderId(tgOrder.order_number));
if (orderId == null) continue;
var tempOrderId = string.Format("{0}{1}", base.StoreId, orderId.Value);
order.OrderId = TryConvertInt64(tempOrderId).Value;
order.StoreOrderId = tgOrder.id.ToString();
order.WarehouseOrderId = tgOrder.order_number;
var orderFromDb = await orderMgr.GetOrder(order.OrderId, base.StoreId);
if (orderFromDb != null) continue; // make sure we only import new order(i.e. doesn't exists in database)
// shipping address
var tgShippingAddress = GetAddress(tgOrder.shipping_address_id);
if (tgShippingAddress == null) continue;
order.ShipFirstName = tgShippingAddress.first_name;
order.ShipLastName = tgShippingAddress.last_name;
order.ShipCompanyName = tgShippingAddress.company_name;
order.ShipAddress1 = tgShippingAddress.address1;
order.ShipAddress2 = tgShippingAddress.address2;
order.ShipCity = tgShippingAddress.suburb;
order.ShipState = tgShippingAddress.state;
order.ShipPostalCode = tgShippingAddress.zip_code;
order.ShipCountry = tgShippingAddress.country;
order.ShipPhoneNumber = tgShippingAddress.phone_number;
order.CustomerEmail = tgOrder.email;
// billing address
var tgBillingAddress = GetAddress(tgOrder.billing_address_id);
if (tgBillingAddress == null) continue;
// line items
var lineItems = GetOrderLineItems(tgOrder.id);
foreach (TGOrderLineItem lineItem in lineItems)
{
var ol = new OrderLine();
if (lineItem.variant_id.HasValue)
{

}
}

orderMgr.Add(order);
}

Everything starts fine and I get no exceptions but I'm getting no results and the code gets stuck one the line that I marked and the memory keeps shooting up. I figured the problem was with the above code because maybe I was doing something wrong. I just don't know where to start as this is my first time dealing with plinq/parallel processing and the tutorials don't show anything this complex.
