(VB.NET UWP/WinRT) Send a Simple Email
Create a simple email and sends it. The SendEmail method establishes a connection (session) with the SMTP server if necessary, and leaves the connection open so that additional sends may proceed using the same session. The SMTP connection (session) may be explicitly closed by calling CloseSmtpSession.
Important: Some SMTP servers do not actually send the email until the connection is closed. In these cases, it is necessary to call CloseSmtpConnection for the mail to be sent. Most SMTP servers send the email immediately, and it is not required to close the connection.
' This example requires the Chilkat API to have been previously unlocked. ' See Global Unlock Sample for sample code. ' The mailman object is used for sending and receiving email. Dim mailman As New Chilkat.MailMan ' Set the SMTP server. mailman.SmtpHost = "smtp.chilkatsoft.com" ' Set the SMTP login/password (if required) mailman.SmtpUsername = "myUsername" mailman.SmtpPassword = "myPassword" ' Create a new email object Dim email As New Chilkat.Email email.Subject = "This is a test" email.Body = "This is a test" email.From = "Chilkat Support <firstname.lastname@example.org>" Dim success As Boolean = email.AddTo("Chilkat Admin","email@example.com") ' To add more recipients, call AddTo, AddCC, or AddBcc once per recipient. ' Call SendEmail to connect to the SMTP server and send. ' The connection (i.e. session) to the SMTP server remains ' open so that subsequent SendEmail calls may use the ' same connection. success = Await mailman.SendEmailAsync(email) If (success <> True) Then Debug.WriteLine(mailman.LastErrorText) Exit Sub End If ' Some SMTP servers do not actually send the email until ' the connection is closed. In these cases, it is necessary to ' call CloseSmtpConnection for the mail to be sent. ' Most SMTP servers send the email immediately, and it is ' not required to close the connection. We'll close it here ' for the example: success = Await mailman.CloseSmtpConnectionAsync() If (success <> True) Then Debug.WriteLine("Connection to SMTP server not closed cleanly.") End If Debug.WriteLine("Mail Sent!")
