How to Send Mail in MVC6 Using C# Code With Attachment

8/29/2016 - By Pranav Singh 0


This article will show you how you can send an email using gmail as smtp server in mvc5 and mvc6 using c#.net with attachment. This application we can use in MVC3, MVC4, MVC5, MVC6.


Now we will create an image folder


So for this article first we will create a new  mvc application and add a controller and create the view for creating the form. This form will contain fields to provide information to send in email. Now add the below code in your view.

@{
    ViewBag.Title = "How to Send Mail in MVC6 Using C# Code With Attachment";
}
@using (Html.BeginForm("Index", "Home", FormMethod.Post, new { enctype = "multipart/form-data" }))
{
    <table width="100%" border="1">
        <tr>
            <td align="right" colspan="2" style="text-align: center"><strong>SEND EMAIL USING GMAIL ACCOUNT IN MVC</strong></td>
        </tr>
        <tr>
            <td align="right">&nbsp;</td>
            <td align="left">
                @ViewBag.Message
            </td>
        </tr>
        <tr>
            <td align="right">To :</td>
            <td align="left">
                <input id="txttoaddress" name="ToEmailId" width="250px" />
            </td>
        </tr>
        <tr>
            <td align="right">Subject :</td>
            <td align="left">
                <input id="txtsubject" name="Subject" width="250px"></input>
            </td>
        </tr>
        <tr>
            <td align="right">Message Body :</td>
            <td align="left">
                <textarea rows="4" cols="50" name="Message" id="txtmessage"></textarea>
            </td>
        </tr>
        <tr>
            <td align="right">Attachment :</td>
            <td align="left">
                <input type="file" name="file" />
            </td>
        </tr>

        <tr>
            <td align="center" colspan="2">
                <input type="submit" text="Send Message" />
            </td>
        </tr>
    </table>
}
In above code I have added some textbox and button control and input file control. Here we need to take care one thing about the name of the control. You must use a specific name of a control. So we use name of the control to access the value of control.

After this we will the below code to the controller.

using MvcApplication8.Models;
using System;
using System.Collections.Generic;
using System.Linq;
using System.Net.Mail;
using System.Web;
using System.Web.Mvc;

namespace MvcApplication8.Controllers
{
    public class HomeController : Controller
    {
        //
        // GET: /Home/
        [HttpGet]
        public ActionResult Index()
        {
            return View();
        }
        [HttpPost]
        public ActionResult Index(string ToEmailId, string Subject, string Message, HttpPostedFileBase file)
        {
            try
            {
                MailMessage mail = new MailMessage();
                mail.To.Add(ToEmailId);
                mail.From = new MailAddress("dotnetpools@gmail.com");
                mail.Subject = Subject;
                string Body = Message;
                mail.Body = Body;
                mail.IsBodyHtml = true;

                //Send Attahment

                System.Net.Mail.Attachment attachment;
                string filename = System.IO.Path.GetFileName(file.FileName);
                /*Saving the file in server folder*/
                file.SaveAs(Server.MapPath("~/Images/" + filename));
                string filepathtoattach = "Images/" + filename;
                attachment = new System.Net.Mail.Attachment(Server.MapPath(filepathtoattach));
                mail.Attachments.Add(attachment);

                SmtpClient smtp = new SmtpClient();
                //SMTP Server Address of gmail
                smtp.Host = "smtp.gmail.com";
                smtp.Port = 587;
                smtp.Credentials = new System.Net.NetworkCredential("dotnetpools@gmail.com", "BlackBery1@#");
                // Smtp Email ID and Password For authentication
                smtp.EnableSsl = true;
                smtp.Send(mail);
                ViewBag.Message = "Message snd successfully";
            }
            catch
            {
                ViewBag.Message = "Error............";
            }

            return View();
        }
    }
}


So in above code I have used the smtp of gmail for sending the email.  In above please check the parameter passed in the httppost method.

In above code I have used System.Net.Mail.Attachment and then I find out the file name and then save it into the images folder. And then I passed the saved file path in mail attachment .
Keep it same as the control names in your view.Now one this after execution if you are getting error message as shown below:

The SMTP server requires a secure connection or the client was not authenticated. The server response was: 5.5.1 Authentication Required. Learn more at

Then follow the below link to resolve the error.


Now we have done. Run the application to check the output.


Now check the received email
