This article explains how to use ASP. NET to send emails, including choosing the email format, priority, attachment, and email internal code.
Now let's gradually explore using ASP. NET to send emails. We will use VB to illustrate the example, but our final code includes VB and C #.
Step 1: Include the namespace
The System. Web. Util namespace is in ASP. NET. This namespace contains all the necessary objects for sending emails.
The object is:
Object Summary
SmtpMail indicates the mail system. Send an email.
MailMessage, such as the sender address and recipient address.
MailFormat, email format-HTML, text, and so on
MailAttachment indicates an email attachment.
MailEncoding enum represents any internal code, such as Base64 or uencode.
MailPriority enum sets mail priority. Value: High, low, normal
<% @ Import Namespace = "System. Web. Util" %>
OK, the first part is complete.

Step 2: MailMessage object example
Declare the MailMessage object.
Dim mailObj AS new MailMessage
MailMessage object attributes:

Attribute description
From sender's address
Recipient's address
Subject
Body
Cc email copy recipient address
BCC email copy recipient address ratio is displayed in the email (BCC)
Priority of a priority email
Bodyencoding email inner code
Bodyformat, in HTML or text format
Attachments email attachment
The following code snippet shows the mailmessage object.
Mailobj. From = "abc@mydomain.com"
Mailobj. To = request. Form ("")
Mailobj. Subject = "Subject of the mail"
Mailobj. Body = "message of the mail"

Use the smtpmail object send method to send emails. The following code snippet is used to send emails
Smtpmail. Send (mailobj)

MailObj. From = Request. Form ("From ")
MailObj. To = Request. Form ("")

MailObj. Subject = "Subject Of the Mail"
MailObj. Body = "Body of the Mail"

'Html-format emails
MailObj. BodyFormat = MailFormat. Html

'Set to advanced priority
MailObj. Priority = MailPriority. High

'Add attachments to emails
'Note: here we create a mailattachment object to add an attachment to the email.
MailObj. Attachments. Add (new MailAttachment ("c: \ test.doc "))
'Use the SmtpMail object to send emails
SmtpMail. Send (mailObj)
