最近根据公司需求,写个邮件发送。这里面的传入的地址信息的参数都是经过加密的,主要是保证用户信息的安全。

using System;using System.Collections.Generic;using System.Configuration;using System.IO;using System.Linq;using System.Net.Mail;using System.Text;using System.Web; namespace CalslNum.Helper{ /// <summary> ///发送邮件类 /// </summary> public class MailService {  /// <summary>   /// 发送邮件程序调用方法 SendMail("abc@126.com", "某某人", "cba@126.com", "你好", "我测试下邮件", "邮箱登录名", "邮箱密码", "smtp.126.com", true,);   /// </summary>   /// <param name="from">发送人邮件地址</param>   /// <param name="fromname">发送人显示名称</param>   /// <param name="to">发送给谁(邮件地址)</param>   /// <param name="subject">标题</param>   /// <param name="body">内容</param>   /// <param name="username">邮件登录名</param>   /// <param name="password">邮件密码</param>   /// <param name="server">邮件服务器 smtp服务器地址</param>   /// <param name= "IsHtml "> 是否是HTML格式的邮件 </param>   /// <returns>send ok</returns>   public static bool SendMail(string from, string fromname, string to, string subject, string body, string server, string username, string password, bool IsHtml)  {   //邮件发送类    MailMessage mail = new MailMessage();   try   {    //是谁发送的邮件     mail.From = new MailAddress(from, fromname);    //发送给谁     mail.To.Add(to);    //标题     mail.Subject = subject;    //内容编码     mail.BodyEncoding = Encoding.Default;    //发送优先级     mail.Priority = MailPriority.High;    //邮件内容     mail.Body = body;    //是否HTML形式发送     mail.IsBodyHtml = IsHtml;    //邮件服务器和端口     SmtpClient smtp = new SmtpClient(server, 25);    smtp.UseDefaultCredentials = true;    //指定发送方式     smtp.DeliveryMethod = SmtpDeliveryMethod.Network;    //发件人身份验证,否则163 发不了     smtp.UseDefaultCredentials = true;    //指定登录名和密码     smtp.Credentials = new System.Net.NetworkCredential(username, password);    //超时时间     smtp.EnableSsl = false;    smtp.Timeout = 10000;    smtp.Send(mail);    return true;   }   catch (Exception)   {    return false;   }   finally   {    mail.Dispose();   }  }   //读取指定URL地址的HTML,用来以后发送网页用   public static string ScreenScrapeHtml(string url)  {   //读取stream并且对于中文页面防止乱码    StreamReader reader = new StreamReader(System.Net.WebRequest.Create(url).GetResponse().GetResponseStream(), System.Text.Encoding.UTF8);   string str = reader.ReadToEnd();   reader.Close();   return str;  }   //发送plaintxt   public static bool SendText(string from, string fromname, string to, string subject, string body, string server, string username, string password)  {   return SendMail(from, fromname, to, subject, body, server, username, password, false);  }   //发送HTML内容   public static bool SendHtml(string from, string fromname, string to, string subject, string body, string server, string username, string password)  {   return SendMail(from, fromname, to, subject, body, server, username, password, true);  }   //发送制定网页   public static bool SendWebUrl(string from, string fromname, string to, string subject, string server, string username, string password, string url)  {   //发送制定网页    return SendHtml(from, fromname, to, subject, ScreenScrapeHtml(url), server, username, password);   }  //默认发送格式   public static bool SendEmailDefault(string ToEmail,string f_username,string f_pass,string f_times)  {   StringBuilder MailContent = new StringBuilder();   MailContent.Append("亲爱的×××会员:<br/>");   MailContent.Append(" 您好!你于");   MailContent.Append(DateTime.Now.ToString("yyyy-MM-dd HH:MM:ss"));   MailContent.Append("通过<a href='#'>×××</a>管理中心审请找回密码。<br/>");   MailContent.Append("   为了安全起见,请用户点击以下链接重设个人密码:<br/><br/>");   string url = "http://www.×××.×××/SignIn/Rest?u=" + f_username + "&s=" + f_pass + "&t=" + f_times; 114 MailContent.Append("<a href='" + url + "'>" + url + "</a><br/><br/>"); 115 MailContent.Append(" (如果无法点击该URL链接地址,请将它复制并粘帖到浏览器的地址输入框,然后单击回车即可。)"); 116 return SendHtml(ConfigurationManager.AppSettings["EmailName"].ToString(), "会员管理中心", ToEmail, "×××找回密码", MailContent.ToString(), ConfigurationManager.AppSettings["EmailService"].ToString(), ConfigurationManager.AppSettings["EmailName"].ToString(), ConfigurationManager.AppSettings["EmailPass"].ToString()); //这是从webconfig中自己配置的。 117 } 118 } 119 }

webconfig配置信息

<add key="EmailName" value="××××@163.com"/><add key="EmailPass" value="××××"/><add key="EmailService" value="smtp.163.com"/>

//说明: 这里面的"EmailService"得与你自己设置邮箱的smtp/POP3/...服务要相同, 大部分是根据@后面的进行配置。我是用163邮箱配置的。 可以根据自己需要自己配置。 

后台调用的方法

 public ActionResult SendEmail(string EmailName)  {   EmailName = Helper.FI_DesTools.DesDecrypt(EmailName);   if (!Regex.IsMatch(EmailName, @"/w+([-+.']/w+)*@/w+([-.]/w+)*/./w+([-.]/w+)*"))   {    return Content("0");   }   string f_username = "";   string f_pass = "";   string f_times = Helper.FI_DesTools.DesEncrypt(DateTime.Now.ToString("yyyy-MM-dd HH:mm:ss"));   List<user> list = (from a in users where a.emailaddress == EmailName select a).ToList();   if (list.Count > 0)   {        f_username = Helper.FI_DesTools.DesEncrypt(list[0].×××);    f_pass = Helper.FI_DesTools.DesEncrypt(list[0].×××);     bool flag = Helper.MailService.SendEmailDefault(EmailName, “×××”,“×××”, “×××”); //这里面的参数根据自己需求自己定,最好进行加密    if (flag)    {     return Content("true");    }    else    {     return Content("false");    }   }   else {    return Content("false");   }  }

发送完邮件效果图如下:
