发送邮件DEMO mvc post 后 清空表单数据

  我做了一个邮件发送demo  

  具体的步骤如下：

  1、首先创建一个实体类   

using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.ComponentModel;
using System.ComponentModel.DataAnnotations;
namespace SendMailMessage.Models
{
    public class EmailModel
    {
        [DisplayName("收件人")]
        [Required(ErrorMessage = "收件人不允许为空！")]
        [RegularExpression(@"(?i)(<[^>]+>|[\w_])*@[\w.-]+\.\w+",ErrorMessage="Emai格式不正确")]
        public string receiver { get; set; }
        [DisplayName("主题")]
        [Required(ErrorMessage = "主题不允许为空！")]
        public string subject { get; set; }
        [DisplayName("信件内容")]
        [Required(ErrorMessage = "信件内容不允许为空！")]
        public string body { get; set; }
    }
}

 2、Controller的内容如下

using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Web.Mvc;
using SendMailMessage.Uitls;
using SendMailMessage.Models;
namespace SendMailMessage.Controllers
{
    public class HomeController : Controller
    {
        //
        // GET: /Home/

        public ActionResult Index()
        {
            
            return View();
        }
        [HttpPost]
        public ActionResult Index(EmailModel model)
        {

            try
            {
                if (ModelState.IsValid)
                {
                    if (EMail.SendEmail(model.receiver, null, null, model.subject, model.body, null))
                    {
                       // TempData["message"] = "发送成功";
                        @ViewBag.message = "发送成功";
                        ModelState.Clear();//model信息 （表单数据）
                    }
                    else
                    {
                       // TempData["message"] = "发送失败";
                        @ViewBag.message = "发送失败";
                    }
                }
            }
            catch(Exception e)
            {
                ModelState.AddModelError("receiver", e.Message);
            }
         
            return View("Index");
           // RedirectToAction("Index");
        }

    }
}

注：ModelState.Clear();//清空model   清空表单的方式有多种  也可刷新页面  使用RedirectToAction("Index");   重新跳转 就需要 TempData["message"]保存提示信息了（也可以使用 Session 或者Cookie）

3、发送Emai类

using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Net.Mail;
using System.Configuration;
using System.Net;
using System.Reflection;
using System.Text;

namespace SendMailMessage.Uitls
{
    #region 邮件服务

    /* 范例：
    // 附件路径
    var filePath = @"O:\UploadImage\05_20110418_113900.bmp,O:\UploadImage\05_20110418_121224.bmp";
    
    EMail email = new EMail("semeichenyan@sina.com.cn", null, null, "测试标题", "测试正文", filePath);
    //EMail email = new EMail("semeichenyan@sina.com.cn", null, null, "测试标题", "测试正文", null);
    //EMail email = new EMail("semeichenyan@sina.com.cn", "semeichenyan@sina.com.cn", "semeichenyan@sina.com.cn", "测试标题", "测试正文", null);
    email.Send();
    */


    public class EMail
    {
        // 实例化一个SmtpClient
        //SmtpClient _smtpClient = new SmtpClient();

        // 实例化一个邮件类

        {
            EMail email = new EMail(toEmail, cc, bcc, subject, body, attachments);
            return email.Send();
        }



        /// <summary>

            //strLocalHostName = System.Net.Dns.GetHostAddresses(strLocalHostName)[0].ToString();
            //fi.SetValue(_smtpClient, strLocalHostName);

            bool result = false;

            try
            {
                // 将smtp的出站方式设为Network
                _smtpClient.DeliveryMethod = SmtpDeliveryMethod.Network;

                // smtp服务器是否启用SSL加密
                _smtpClient.EnableSsl = false;

                // 指定smtp服务器地址
                _smtpClient.Host = _smtp;

                // 指定smtp服务器的端口，默认是25，如果采用默认端口，可省去
                //smtp.Port = 25;             

                // 如果你的SMTP服务器不需要身份认证，则使用下面的方式，不过，目前基本没有不需要认证的了
                //smtp.UseDefaultCredentials = true;

                // 如果需要认证，则用下面的方式
                _smtpClient.Credentials = new NetworkCredential(_fromEmail, _senderPassword);

                // 邮件的优先级，分为Low、Normal、 High，通常用Normal即可
                _mailMessage.Priority = MailPriority.High;

                // 收件方看到的邮件来源；第一个参数是发信人邮件地址，第二参数是发信人显示的名称，第三个参数是第二个参数所使用的编码，如果指定不正确，则对方收到后显示乱码，936是简体中文的codepage值
                _mailMessage.From = new MailAddress(_fromEmail, _displayName, Encoding.GetEncoding(936));

                // ReplyTo 表示对方回复邮件时默认的接收地址，即：你用一个邮箱发信，但却用另一个来收信，后两个参数的意义，同From
                _mailMessage.ReplyTo = new MailAddress(_fromEmail, _displayName, Encoding.GetEncoding(936));

                // 邮件的接收者，支持群发，多个地址之间用半角逗号分开
                _mailMessage.To.Add(ToEmail);

                // 抄送
                if (!string.IsNullOrEmpty(CC))
                {
                    _mailMessage.CC.Add(CC);
                }

                // 密送
                if (!string.IsNullOrEmpty(Bcc))
                {
                    _mailMessage.Bcc.Add(Bcc);
                }

                // 邮件标题
                _mailMessage.Subject = Subject;

                // 这里非常重要，如果你的邮件标题包含中文，这里一定要指定，否则对方收到的极有可能是乱码
                _mailMessage.SubjectEncoding = Encoding.GetEncoding(936);

                // 邮件正文是否是HTML格式

}

 这个类比较混乱 还带优化 希望大家见谅

4、view部分

@model SendMailMessage.Models.EmailModel

@{
    ViewBag.Title = "Index";
}



<script src="@Url.Content("~/Scripts/jquery.validate.min.js")" type="text/javascript"></script>
<script src="@Url.Content("~/Scripts/jquery.validate.unobtrusive.min.js")" type="text/javascript"></script>

@using (Html.BeginForm()) {
    @Html.ValidationSummary(true)
    <fieldset>
        <legend>邮件发送</legend>

        <div class="editor-label">
            @Html.LabelFor(model => model.receiver)
        </div>
        <div class="editor-field">
            @Html.EditorFor(model => model.receiver)
            @Html.ValidationMessageFor(model => model.receiver)
        </div>

        <div class="editor-label">
            @Html.LabelFor(model => model.subject)
        </div>
        <div class="editor-field">
            @Html.EditorFor(model => model.subject)
            @Html.ValidationMessageFor(model => model.subject)
        </div>

        <div class="editor-label">
            @Html.LabelFor(model => model.body)
        </div>
        <div class="editor-field">
            @Html.EditorFor(model => model.body)
            @Html.ValidationMessageFor(model => model.body)
        </div>
        @ViewBag.message
       
        <p>
            <input type="submit" value="Create" />
        </p>
    </fieldset>
}

<div>
    @Html.ActionLink("Back to List", "Index")
</div>

对了 忘记配置webconfig文件了

 <appSettings>
    <add key="ClientValidationEnabled" value="true"/>
    <add key="UnobtrusiveJavaScriptEnabled" value="true"/>
    <!-- 邮件服务组件 start -->
    <!--发件使用的邮箱地址-->
    <add key="EmailServer" value="smtp.126.com"/>
    <!--发件使用的邮箱地址-->
    <add key="EmailSender" value="********"/>
    <!--发件邮箱地址密码-->
    <add key="EmailServer_Pwd" value="*****8"/>
    <!--显示在邮件上的发件人名称-->
    <add key="EmailSenderName" value="邮差"/>
    <!-- 邮件服务组件 end -->
  </appSettings>

ok了
