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://"/>

//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：
