            <tr>
                <td style="width: 393px">

            </tr>
        </table>
    </form>
</body>
</html>

2、Default.aspx.cs代码如下：
复制代码代码如下:
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：
