1、Default.aspx代码如下：
代码如下:
<%@ Page Language="C#" AutoEventWireup="true" CodeFile="Default.aspx.cs" Inherits="_Default" ValidateRequest="false" %>
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">

<asp:Button ID="Button2" runat="server" Text="返回" OnClick="Button2_Click" /></td>
</tr>
</table>
</form>
</body>
</html>
2、Default.aspx.cs代码如下：
代码如下:
using System;
using System.Data;
using System.Configuration;
using System.Web;
using System.Web.Security;
using System.Web.UI;
using System.Web.UI.WebControls;
using System.Web.UI.WebControls.WebParts;
using System.Web.UI.HtmlControls;
//倒入命名空间
using System.Net;
using System.Net.Mail;
public partial class _Default : System.Web.UI.Page
{
protected void Page_Load(object sender, EventArgs e)
{
}
protected void Button1_Click(object sender, EventArgs e)
{
////设置发件人信箱,及显示名字
MailAddress from = new MailAddress("zgdx0503@cpp114.com", "延边职大信息中心");
//设置收件人信箱,及显示名字
MailAddress to = new MailAddress(TextBox1.Text, "0503班");
//创建一个MailMessage对象
MailMessage oMail = new MailMessage(from, to);
oMail.Subject = TextBox2.Text; //邮件标题
oMail.Body = TextBox3.Text; //邮件内容
oMail.IsBodyHtml = true; //指定邮件格式,支持HTML格式
oMail.BodyEncoding = System.Text.Encoding.GetEncoding("GB2312");//邮件采用的编码
oMail.Priority = MailPriority.High;//设置邮件的优先级为高
//发送邮件服务器
SmtpClient client = new SmtpClient();
client.Host = "mail.cpp114.com"; //指定邮件服务器
client.Credentials = new NetworkCredential("zgdx0503@cpp114.com", "123456");//指定服务器邮件,及密码
//发送
try
{
client.Send(oMail); //发送邮件
Label1.Text = "恭喜你！邮件发送成功。";
}
catch
{
Label1.Text = "邮件发送失败，检查网络及信箱是否可用。";
}
oMail.Dispose(); //释放资源
TABLE1.Visible = false;
Table2.Visible = true;
}
protected void Button2_Click(object sender, EventArgs e)
{
//返回，继续发送
Response.Redirect(Request.Url.ToString());
TABLE1.Visible = true;
Table2.Visible = false;
}
}
3、运行并输入测试信箱zgdx0503@tom.com,（密码：123456）。如下所示：
4、打开信箱查看
