Asp. NET send email Complete instance

This article illustrates the many possibilities of sending emails in asp.net, covering such aspects as email format, priority, attachment and email encoding.

Asp. NET is given a new object to send email, named SmtpMail. When you use the SmtpMail object to send e-mail from a asp.net page, you can follow these simple steps:

▲ contains the namespaces required for the class of the message;

▲ example an information object, set the attribute;

▲ send a message using the Send method of the SmtpMail object instance.

Now we're going to take a step-by-step look at the process of sending emails from a asp.net page. We use VB to illustrate this example, the final will include VB and C # complete code.

First step: Include namespaces

Introduce the System.Web.Util namespace in the ASP.net page, which includes all the objects necessary to send an email. These objects are:

SmtpMail：代表邮件系统，用于发送email。
MailMessage：代表一个信息，其属性包括发件人地址、收件人地址等。
MailFormat：代表信息的格式：HTML、文本等。
MailAttachment：代表一个email附件。
MailEncoding enum：代表Base64 或Uuencode的任何编码。取值范围：Base64、UUencode
MailPriority enum：用来为信息设置优先权。值为：高、低、一般。
<% @Import Namespace = "System.Web.Util" %>

Step Two: Example MailMessage object

Use the following statement to sample the MailMessage object:

Dim Mailobj as New MailMessage

Prepares the message with the properties of the MailMessage object. The MailMessage object has the following properties:

From：发件人的Email地址
To：收件人的Email地址
Subject：email的主题
Body：email的主体
CC：email抄送的收件人列表
BCC：email暗送的收件人列表
Priority：信息的优先权：高、低或一般
BodyEncoding：信息体的编码，如果有的话，就是Base64或UUencode
BodyFormat：信息的格式：Html 或text
Attachments：附加到email 的MailAttachment对象列表，主要就是对这个对象集合的一个引用
