This article will show you how you can send an email using gmail as smtp server in mvc5 and mvc6 using c#.net. This article you can use in MVC2, MVC3, MVC4, MVC5, MVC6.

Some of my previous articles are as follows: Gmail Smtp Error : The SMTP server requires a secure connection or the client was not authenticated. The server response was: 5.5.1 Authentication Required.

So for this article first we will create a new  asp.net 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.

@model MvcApplication8.Models.CountryModel @{     ViewBag.Title = "Send Mail In MVC5 and MVC6 In C# Using Gmail"; } @using (Html.BeginForm("Index", "Home")) {     <table width="100%" border="1">         <tr>             <td align="right" colspan="2" style="text-align: center"><strong>SEND EMAIL USING GMAIL ACCOUNT</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="center" colspan="2">                 <input type="submit" text="Send Message" />             </td>         </tr>     </table> }

In above code I have added some textbox and button 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)         {             try             {                 MailMessage mail = new MailMessage();                 mail.To.Add(ToEmailId);                 mail.From = new MailAddress("yourgmailid@gmail.com");                 mail.Subject = Subject;                 string Body = Message;                 mail.Body = Body;                 mail.IsBodyHtml = true;                 SmtpClient smtp = new SmtpClient();                 //SMTP Server Address of gmail                 smtp.Host = "smtp.gmail.com";                 smtp.Port = 587;                 smtp.Credentials = new System.Net.NetworkCredential("yourgmailid@gmail.com", "your password");                 // Smtp Email ID and Password For authentication                 smtp.EnableSsl = true;                 smtp.Send(mail);                 ViewBag.Message = "Your Message Send 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. 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
