發送郵件DEMO -------mvc post 后 清空表單數據

  我做了一個郵件發送demo  

  具體的步驟如下：

  1、首先創建一個實體類   

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 = "收件人不允許為空！")]
        [RegularExpression(@"(?i)(<[^>]+>|[\w_])*@[\w.-]+\.\w+",ErrorMessage="Emai格式不正確")]
        public string receiver { get; set; }
        [DisplayName("主題")]
        [Required(ErrorMessage = "主題不允許為空！")]
        public string subject { get; set; }
        [DisplayName("信件內容")]
        [Required(ErrorMessage = "信件內容不允許為空！")]
        public string body { get; set; }
    }
}

 2、Controller的內容如下

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"] = "發送成功";
                        @ViewBag.message = "發送成功";
                        ModelState.Clear();//model信息 （表單數據）
                    }
                    else
                    {
                       // TempData["message"] = "發送失敗";
                        @ViewBag.message = "發送失敗";
                    }
                }
            }
            catch(Exception e)
            {
                ModelState.AddModelError("receiver", e.Message);
            }
         
            return View("Index");
           // RedirectToAction("Index");
        }

    }
}

注：ModelState.Clear();//清空model   清空表單的方式有多種  也可刷新頁面  使用RedirectToAction("Index");   重新跳轉 就需要 TempData["message"]保存提示信息了（也可以使用 Session 或者Cookie）

3、發送Emai類

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 郵件服務

    /* 范例：
    // 附件路徑
    var filePath = @"O:\UploadImage\05_20110418_113900.bmp,O:\UploadImage\05_20110418_121224.bmp";
    
    EMail email = new EMail("[e-mail]", null, null, "測試標題", "測試正文", filePath);
    //EMail email = new EMail("[e-mail]", null, null, "測試標題", "測試正文", null);
    //EMail email = new EMail("[e-mail]", "[e-mail]", "[e-mail]", "測試標題", "測試正文", null);
    email.Send();
    */


    public class EMail
    {
        // 實例化一個SmtpClient
        //SmtpClient _smtpClient = new SmtpClient();

        // 實例化一個郵件類

            return email.Send();
        }



        /// <summary>

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

            bool result = false;

            try
            {
                // 將smtp的出站方式設為Network

                // 指定smtp服務器地址
                _smtpClient.Host = _smtp;

                // 指定smtp服務器的端口，默認是25，如果采用默認端口，可省去
                //smtp.Port = 25;             

                // 如果你的SMTP服務器不需要身份認證，則使用下面的方式，不過，目前基本沒有不需要認證的了
                //smtp.UseDefaultCredentials = true;

                _smtpClient.Credentials = new NetworkCredential(_fromEmail, _senderPassword);

                // 郵件的優先級，分為Low、Normal、 High，通常用Normal即可
                _mailMessage.Priority = MailPriority.High;

                // 收件方看到的郵件來源；第一個參數是發信人郵件地址，第二參數是發信人顯示的名稱，第三個參數是第二個參數所使用的編碼，如果指定不正確，則對方收到后顯示亂碼，936是簡體中文的codepage值
                _mailMessage.From = new MailAddress(_fromEmail, _displayName, Encoding.GetEncoding(936));

                // ReplyTo 表示對方回復郵件時默認的接收地址，即：你用一個郵箱發信，但卻用另一個來收信，后兩個參數的意義，同From
                _mailMessage.ReplyTo = new MailAddress(_fromEmail, _displayName, Encoding.GetEncoding(936));

                // 郵件的接收者，支持群發，多個地址之間用半角逗號分開
                _mailMessage.To.Add(ToEmail);

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

                // 密送
                if (!string.IsNullOrEmpty(Bcc))
                {

 這個類比較混亂 還帶優化 希望大家見諒

 

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>郵件發送</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>

對了 忘記配置webconfig文件了

 <appSettings>
    <add key="ClientValidationEnabled" value="true"/>
    <add key="UnobtrusiveJavaScriptEnabled" value="true"/>
    <!-- 郵件服務組件 start -->
    <!--發件使用的郵箱地址-->
    <add key="EmailServer" value="smtp.126.com"/>
    <!--發件使用的郵箱地址-->
    <add key="EmailSender" value="********"/>
    <!--發件郵箱地址密碼-->
    <add key="EmailServer_Pwd" value="*****8"/>
    <!--顯示在郵件上的發件人名稱-->
    <add key="EmailSenderName" value="郵差"/>
    <!-- 郵件服務組件 end -->
  </appSettings>

 

ok了

預覽一哈
