用asp.net发送电子邮件

.net提供了强大的功能,其中就包括发送邮件上.经过仔细研究才发现用.net发送电子邮件是很简单的一件事情.现在我们就来看一下.
首先添加命名空间

Using System.Net.Mail

下面我们看发送邮件的代码部分:( 注意:网易的邮件服务器是smtp.163.com)

MailAddress from = new MailAddress(TBMailFrom.Text);

MailAddress to = new MailAddress(TBMailTo.Text);

MailMessage message = new MailMessage(from,to);

message.Subject = TBSubject.Text;

message.Body = TBDescript.Text;

if (FileUpload1.PostedFile.FileName != "" )

{

Attachment att = new Attachment(FileUpload1.PostedFile.FileName);

message.Attachments.Add(att);

}

SmtpClient client = new SmtpClient( " smtp.163.com " );

smtp.Credentials = new System.Net.NetworkCredential( " username " , " password " );

client.Send(message);

我们这里在发送邮件的时候只是设置了邮件收,发件人,邮件主题和邮件正文部门,在.net里面还可以设置发送邮件的文本格式,优先级等.我们这里就不说明了,相信看看就会明白的.(message.Priority;设置优先级.mssage.Headers;设置邮件的标头. message.CC;设置抄送.message.IsBodyHtml;设置是否以html格式发送邮件)
下面是对页面的设置:

< body >
2

< form id = " form1 " runat = " server " >
3

< div >
4

< table style = " width: 268px " >
5

< tr >< td >
6

< asp:Label ID = " Label4 " runat = " server " Text = " 发件人: " ></ asp:Label ></ td >
7

< td >
8

< asp:TextBox ID = " TBMailFrom " runat = " server " ></ asp:TextBox ></ td ></ tr >
9

< tr >
10

< td style = " width: 101px " >
11

< asp:Label ID = " Label1 " runat = " server " Text = " 收件人： " ></ asp:Label ></ td >
12

< td >
13

< asp:TextBox ID = " TBMailTo " runat = " server " ></ asp:TextBox ></ td >
14

</ tr >
15

< tr >
16

< td style = " width: 101px " >
17

< asp:Label ID = " Label2 " runat = " server " Text = " 邮件主题： " ></ asp:Label ></ td >
18

< td >
19

< asp:TextBox ID = " TBSubject " runat = " server " ></ asp:TextBox ></ td >
20

</ tr >
21

< tr >< td colspan = " 2 " >
22

< asp:FileUpload ID = " FileUpload1 " runat = " server " Width = " 259px " /></ td >
23

</ tr >
24

< tr >
25

< td colspan = " 2 " >
26

< asp:Label ID = " Label3 " runat = " server " Text = " 邮件正文: " ></ asp:Label ></ td >
27

</ tr >
28

< tr >
29

< td colspan = " 2 " >
30

< asp:TextBox ID = " TBDescript " runat = " server " Height = " 97px " TextMode = " MultiLine " Width = " 247px " ></ asp:TextBox ></ td >
31

</ tr >
32

< tr >
33

< td colspan = " 2 " >
34

< asp:Button ID = " BSend " runat = " server " OnClick = " BSend_Click " Text = " 发送 " /></ td >
35

</ tr >
36

</ table >
37

</ div >
38

</ form >
39

</ body >

好了,发送邮件的功能就实现了,试一下.是不是比较方便.
