使用.net实现发送Email

源代码如下：

using System;
using System.Data;
using System.Configuration;
using System.Collections;
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;
using System.Net.Mail;
//using System.Web.Mail;
//using System.Web.Mail;

public partial class mail : System.Web.UI.Page
{
    protected void Page_Load(object sender, EventArgs e)
    {
        MailAddress MessageFrom = new MailAddress("jsqdnsw@163.com"); //发件人邮箱地址
        string MessageTo = "jsqdnsw@vip.qq.com"; //收件人邮箱地址
        string MessageSubject = "邮件主题"; //邮件主题
        string MessageBody = "这里是邮件内容。"; //邮件内容
        if (Send(MessageFrom, MessageTo, MessageSubject, MessageBody))
        {
            Response.Write("发送邮件成功");
        }
        else
        {
            Response.Write("发送邮件失败");
        }
    }

    /// <summary>
    /// 发送电子邮件
    /// </summary>
    /// <param name="MessageFrom">发件人邮箱地址</param>
    /// <param name="MessageTo">收件人邮箱地址</param>
    /// <param name="MessageSubject">邮件主题</param>
    /// <param name="MessageBody">邮件内容</param>
    /// <returns></returns>
    public bool Send(MailAddress MessageFrom, string MessageTo, string MessageSubject, string MessageBody)
    {
        MailMessage message = new MailMessage();
      
       // if (FileUpload1.PostedFile.FileName != "")
       // {
        //  Attachment att = new Attachment("d://test.txt");//发送附件的内容
       //    message.Attachments.Add(att);
       // }
      
        message.From = MessageFrom;
        message.To.Add(MessageTo); //收件人邮箱地址可以是多个以实现群发
        message.Subject = MessageSubject;
        message.Body = MessageBody;
        //message.Attachments.Add(objMailAttachment);
        message.IsBodyHtml = false; //是否为html格式
        message.Priority = MailPriority.High; //发送邮件的优先等级
      
        SmtpClient sc = new SmtpClient();
        sc.Host = "smtp.163.com"; //指定发送邮件的服务器地址或IP
        sc.Port = 25; //指定发送邮件端口
        sc.Credentials = new System.Net.NetworkCredential("jsqdnsw@163.com", "***"); //指定登录服务器的用户名和密码
       
        try
        {
            sc.Send(message); //发送邮件
        }
        catch
        {
            return false;
        }
        return true;

    }
}

 

 

/*注意：像有些163邮箱的不能发送email可能是你的邮箱没有开通这项服务导致的，据说163邮箱在06年11月份请申请的才有这项服务*/
