Sending Multiple Recepients in a single mail: Consequences - c#

While sending email via System.Net.Mail to multiple recipients (one single email with multiple recipients), if one recipients address fail, will the rest reach the email?
There might be duplicates of the same question, but I'm asking something different in contrast.
For prompting such question, I was taken into consideration of Email clients available like Outlook where such does not happen even if one single address failed. Perhaps, System.Net.Mail is a lightweight client and does not allow such functionality? Or is it the way I'm writing my code incorrectly.
I was asked as if why this happens, hope I can get an explanation so that I can pass it by.
I was running such a scenario from my code below:
public void sendBusinessEmail(communication.email.business.config.BusinessEmailList[] aEmailList)
{
System.Net.Mail.MailMessage objMsg = null;
string[] aEmail = null;
System.Net.Mail.SmtpClient objSmtpClient = null;
int iRetries = 0;
if (aEmailList == null)
{
return;
}
try
{
if (Properties.Settings.Default.IS_SMTP_TLS)
{
objSmtpClient = getSMTP_TLS_Client();
ServicePointManager.ServerCertificateValidationCallback = delegate(object s, X509Certificate certificate, X509Chain chain, SslPolicyErrors sslPolicyErrors) { return true; };
}
else
{
objSmtpClient = getSMTP_Default_Client();
}
foreach (communication.email.business.config.BusinessEmailList obj in aEmailList)
{
try
{
objMsg = new System.Net.Mail.MailMessage();
objMsg.From = new System.Net.Mail.MailAddress("jkstock#keells.com", "JKSB Business Services");
aEmail = obj.Emails;
if (Properties.Settings.Default.TO_TEST_EMAIL)
{
objMsg.To.Add(Properties.Settings.Default.TO_TEST_EMAIL_ADDRESS.ToString());
for (int i = 0; i < aEmail.Length; i++)
{
objMsg.Body += aEmail[i] + Environment.NewLine;
}
}
else
{
for (int i = 0; i < aEmail.Length; i++)
{
objMsg.To.Add(new System.Net.Mail.MailAddress(aEmail[i]));
}
objMsg.Body = obj.EmailBody;
}
objMsg.Subject = checkAllReadySent(obj.EmailSubject);
objMsg.Attachments.Add(new System.Net.Mail.Attachment(obj.AttachmentPath, (System.IO.Path.GetExtension(obj.AttachmentPath) == ".pdf" ? System.Net.Mime.MediaTypeNames.Application.Pdf : System.Net.Mime.MediaTypeNames.Application.Octet)));
//sending emails
//send for 5 times if error persists, unless otherwise success
for (int i = 0; i < 5; i++)
{
try
{
objSmtpClient.Send(objMsg);
obj.updateLog("OK", (i+1));
break;
}
catch (Exception e)
{
if (i == 4)
{
obj.updateLog(e.Message, (i+1));
}
}
}
objMsg = null;
}
catch (System.Net.Mail.SmtpFailedRecipientsException e0)
{
obj.updateLog("Invalid Recipient(s)",0);
}
catch (Exception e1)
{
obj.updateLog("Error",0);
}
}
objSmtpClient = null;
}
catch (Exception e2)
{
MessageBox.Show(e2.Message);

Multithreaded Selenium Bot does not work correctly

I wrote a bot in C#, I used Selenium.
Problem: When I start more threads at same time, the bot does the work in the first window. All of the e-mail addresses are being added to the "E-mail" textbox in the same window instead of one e-mail address per window.
But it should look like:
Start function: DivisionStart()
private void DivisionStart() {
foreach(var account in BotConfig.AccountList) {
while (CurrentBotThreads >= BotConfig.MaxLoginsAtSameTime) {
Thread.Sleep(1000);
}

CurrentBotThreads++;
int startIndex = (StartedBotThreads * BotConfig.AdsPerAccount + 1) - BotConfig.AdsPerAccount - 1;
int stopIndex = BotConfig.AdsPerAccount * CurrentBotThreads;
if (stopIndex > BotConfig.ProductList.Count) {
stopIndex = BotConfig.ProductList.Count;
}
Debug.Print("Thread: " + StartedBotThreads);
var adList = GetAdListBy(startIndex, stopIndex);
foreach(var ad in adList) {
Debug.Print("Für thread: " + StartedBotThreads + " | Anzeige: " + ad.AdTitle);

If I remove the Thread.Sleep(5000); in the DivisionStart function it will work, but I need it I actually want to wait for a found proxy but I simulated it with Thread.Sleep
How can I solve my problem?
Thanks for any answer!
I fixed it.
I used UndetectedChromeDriver wich does not use different ports.
I use another Undetected driver now.
Thank you all

Execute Task.Run() in ASP.NET ActionResult without waiting for result

Below is the function where I am trying to execute a function in the background and then carry on without waiting for a result from it.
When debugging the task itself is executed but the actual function within it does not. The rest of the code then carries on like normal.
What could be the issue as there is no error produced after that to indicate otherwise?
This is on a page load.

Xamarin.forms Device contact is not getting updated

I have a Xamarin.Forms based application which uses operation with device contact like adding new contact and updating existing contact. Adding new contacts works, but update contact is not working. I used DependencyService of Xamarin.forms to update contacts on android. First i lookup for that contact and get its' Id if it exist.
Below is my code
void OnUpdate(){
var Id = LookupByPhone(phoneNumber, companyName+ " " + teamName);
if(Id!="0")
{
UpdateContact(phoneNumber, Id,companyName,teamName);
return;
}
}
string LookupByPhone(string phoneNumber, string query = "")
{
var Id = "0";
try
{
var context = MainActivity.Instance;
var uri = ContactsContract.Contacts.ContentUri;
uri = ContactsContract.CommonDataKinds.Phone.ContentUri;
string[] projection = {
ContactsContract.Contacts.InterfaceConsts.Id,
InterfaceConsts.DisplayName,
ContactsContract.CommonDataKinds.Phone.Number
};
var cursor = context.ContentResolver.Query(uri, projection, null, null, null);
if (cursor.MoveToFirst())
{
do
{
var id = cursor.GetString(cursor.GetColumnIndex(projection[0]));
var nm = cursor.GetString(cursor.GetColumnIndex(projection[1]));
var number = cursor.GetString(cursor.GetColumnIndex(projection[2]));
Id = id;
if (nm == query)
break;
//break;
} while (cursor.MoveToNext());
}
cursor.Close();
}
catch (Exception ex)
{
LogController.LogError(ex);
}
return Id;
}
void UpdateContact(string phonenumber, string id, string givenName, string familyName)
{
ContentProviderOperation.Builder builder = ContentProviderOperation.NewUpdate(ContactsContract.Data.ContentUri);
List<ContentProviderOperation> ops = new List<ContentProviderOperation>();
if (!string.IsNullOrWhiteSpace(givenName) && !string.IsNullOrWhiteSpace(familyName))
{
// Name
String nameSelection = ContactsContract.Data.InterfaceConsts.ContactId + " = ? AND "
+ ContactsContract.Data.InterfaceConsts.Mimetype + " = ? ";
String[] nameSelectionArgs = {
id.ToString(),
ContactsContract.CommonDataKinds.StructuredName.ContentItemType
};
builder.WithSelection(nameSelection, nameSelectionArgs);
builder.WithValue(ContactsContract.CommonDataKinds.StructuredName.GivenName, givenName);
builder.WithValue(ContactsContract.CommonDataKinds.StructuredName.FamilyName, familyName);
builder.WithValue(ContactsContract.CommonDataKinds.StructuredName.DisplayName, givenName + " " + familyName);
ops.Add(builder.Build());
}
#region Phone update
// CellPhone
String phoneSelection = ContactsContract.Data.InterfaceConsts.ContactId + " = ? AND " +
ContactsContract.Data.InterfaceConsts.Mimetype + " = ? AND " +
ContactsContract.CommonDataKinds.Phone.InterfaceConsts.Type + " = ?";
String[] phoneselectionArgs = {
id.ToString(),
ContactsContract.CommonDataKinds.Phone.ContentItemType,
PhoneDataKind.Mobile.ToString()
};
builder = ContentProviderOperation.NewUpdate(ContactsContract.Data.ContentUri);
builder.WithSelection(phoneSelection, phoneselectionArgs);
builder.WithValue(ContactsContract.CommonDataKinds.Phone.Number, phonenumber);
builder.WithValue(ContactsContract.CommonDataKinds.Phone.InterfaceConsts.Type, PhoneDataKind.Mobile.ToString());
ops.Add(builder.Build());
#endregion
// Update the contact
ContentProviderResult[] result;
try
{
// the result return count{0}
var result = MainActivity.Instance.ContentResolver.ApplyBatch(ContactsContract.Authority, ops);
}
catch (Exception ex)
{
LogController.LogError("Error updating phone:" + phonenumber,ex);
}
}
There are no error or exception. Any thought on this.
The method which gets the id should be like this (I removed the first parameter since it's not used in your method):
string LookupByPhone(string name)
{
string id = "0";
var uri = ContactsContract.Contacts.ContentUri;
var cursor = this.ContentResolver.Query(
uri,
new String[] { ContactsContract.Contacts.InterfaceConsts.Id },
ContactsContract.Contacts.InterfaceConsts.DisplayName +
"='" + name + "'", null, null);
if (cursor.MoveToNext())
{
id = cursor.GetString(cursor.GetColumnIndex(ContactsContract.Contacts.InterfaceConsts.Id));
}
cursor.Close();
return id;
}
You can see I get the id by query the name that is what you are using companyName + " " + teamName

Cortana Background task crashes on mobile but works perfectly on desktop

Been looking at this for the past few days now and I'm no closer to a solution. The code below is based on the CortanaVoiceCommand sample at https://github.com/Microsoft/Windows-universal-samples/tree/master/Samples/CortanaVoiceCommand and the code works perfectly on desktop but the background task is crashing on mobile each time.
In OnTaskCanceled the BackgroundTaskCancellationReason always reports as SystemPolicy but I'm no closer to finding a solution.
Appreciate any help anyone can suggest.

error in displaying the list from database

i am trying to get the list of programs from database. error is
ArgumentNullException was unhandled by user code in cacheUtilites GetTrainingProgram Method.
Here is my Controller code:
[HttpGet]
[Authorize(Roles = "Affiliate")]
public ActionResult GetTrainingPrograms(int? affiliateId, string searchStr, bool? active, string sort, int? start, int? limit)

int affId = UserData.AffiliateID;

affId = affiliateId.Value;
}
string searchStrLower = string.Empty;
string queryStr = String.Concat(affId);
// The start point in the list of Training Programs
if (start != null)
{
queryStr = String.Concat(queryStr, "-", start.Value);
}

if (active != null)
