So for this article first we will create a new application and add the below code in controller class file.

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 Name, string EmailId, string PhoneNo, string Subject, string Message)         {             try             {                 MailMessage mail = new MailMessage();                 mail.To.Add(EmailId);                 mail.From = new MailAddress("youremailid@gmail.com");                 mail.Subject = Subject;                 string userMessage = "";                 userMessage = "<br/>Name :" + Name;                 userMessage = userMessage + "<br/>Email Id: " + EmailId;                 userMessage = userMessage + "<br/>Phone No: " + PhoneNo;                 userMessage = userMessage + "<br/>Message: " + Message;                 string Body = "Hi, <br/><br/> A new enquiry by user. Detail is as follows:<br/><br/> " + userMessage + "<br/><br/>Thanks";                 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("youremailid@gmail.com", "Password");                 // Smtp Email ID and Password For authentication                 smtp.EnableSsl = true;                 smtp.Send(mail);                 ViewBag.Message = "Thank you for contacting us.";             }             catch             {                 ViewBag.Message = "Error............";             }             return View();         }     } }

In above code I have create httpget an httppost attribute. In above code I have used gmail as smtp server to send the detail in email.

Now we will create the view and add the below code.

@{     ViewBag.Title = "Contact Us Form in MVC5 & MVC6 C#"; } @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">Name :</td>             <td align="left">                 <input id="txtName" name="Name" width="250px" />             </td>         </tr>         <tr>             <td align="right">Your Email id  :</td>             <td align="left">                 <input id="txttoaddress" name="EmailId" width="250px" />             </td>         </tr>         <tr>             <td align="right">Phone No :</td>             <td align="left">                 <input id="txtPhoneno" name="PhoneNo" 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 :</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 I have create a contact us form. In this we need to take care of the controls name. because in MVC we can only detect the added control value by it’s name.  This function will send the enquiry to the admin of the website.

So in above code I have used the smtp of gmail for sending the email.  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
