在asp.net 2.0中发送邮件

作者：webabcd


1、在web.config中的<configuration>内加入如下配置信息（host―smtp服务地址；port―端口号；userName―用户名；password―密码。请自行修改）。

<system.net>
        <mailSettings>

            <smtp>
                <network host="smtpserver" port="25" userName="uid" password="pwd" />
            </smtp>

        </mailSettings>
    </system.net>

2、aspx页面HTML代码

 

< table border ="0" >
                 < tr >
                         < td >
                                发件人
                         </td>
                         < td >
                                 < asp:TextBox runat ="server" ID ="emailfrom" > </asp:TextBox>
                         </td>
                 </tr>
                 < tr >
                         < td >
                                收件人
                         </td>
                         < td >
                                 < asp:TextBox runat ="server" ID ="emailto" > </asp:TextBox>
                         </td>
                 </tr>
                 < tr >
                         < td >
                                主题
                         </td>
                         < td >
                                 < asp:TextBox runat ="server" ID ="subject" > </asp:TextBox>
                         </td>
                 </tr>
                 < tr >
                         < td >
                                附件
                         </td>
                         < td >
                                 < asp:FileUpload ID ="attachment" runat ="server" />
                         </td>
                 </tr>
                 < tr >
                         < td >
                                内容
                         </td>
                         < td >
                                 < asp:TextBox runat ="server" ID ="body" TextMode ="MultiLine" Columns ="50" Rows ="10" > </asp:TextBox>
                         </td>
                 </tr>
                 < tr >
                         < td colspan ="2" align ="center" >
                                 < asp:Button runat ="server" ID ="btnSend" Text ="发送" OnClick ="btnSend_Click" />
                         </td>
                 </tr>
         </table>

 

3、实例化一个MailMessage并设置其属性

MailMessage mm = new MailMessage(emailfrom.Text, emailto.Text);

                mm.Subject = subject.Text;
                mm.Body = body.Text;
                 // HTML格式
                mm.IsBodyHtml = true;

                 // 添加附件
                mm.Attachments.Add( new Attachment(attachment.PostedFile.InputStream, attachment.FileName));

                 /*其他如抄送、优先级之类的都可以在MailMessage类的属性中设置*/

 

4、实例化一个SmtpClient，调用其Send方法，参数为MailMessage对象

SmtpClient sc = new SmtpClient();

                 // 编程方式设置smtp（不用web.config）
                 // sc.Host = "";
                 // sc.Port = 25;
                 // sc.Credentials = new NetworkCredential("username", "password");

                 try
                {
                        sc.Send(mm);
                        Response.Write( "ok");
                }
                 catch (Exception ex)
                {
                         // 与smtp相关的错误
                         if (ex is SmtpException)
                        {
                                 // ex.ToString();
                                Response.Write( "smtp发信失败");
                        }
                         else
                        {
                                Response.Write(ex.ToString());
                        }
                }

 

OK
