How to send email from asp.net MVC application using web.config

In this article I am going to explain how to send email from asp.net MVC application using web.config
. 
Description:
If you don’t have SMTP server to send email then you can use Gmail smtp server to send email from your MVC application. To send email from web.config file you have to            set appsetting.
  
Implementation:
Open the web.config file of project. Set key in appsettings. After that mailsettings as shown below:

<appSettings>
    <add key="Email" value="Emailaddress@gmail.com"/>
  </appSettings>
  <system.net>
    <mailSettings>
      <smtp deliveryMethod="Network">
        <network enableSsl="true" port="587" host="smtp.gmail.com" userName=" Emailaddress@gmail.com" password="password"/>
      </smtp>
    </mailSettings>
  </system.net>


Add controller
Add an empty controller to project. Create an Actionresult to send email.

using System.Net;
namespace mvctest2017.Controllers
{
  
    public class SendemailController : Controller
    {
        public ActionResult Index()
        {
            return View();
        }
        public ActionResult SendEmail()
        {
            return View();
        }
        [HttpPost]
public ActionResult SendEmail(string Name, string Subject,string EmailID, string message)
        {
            if (ModelState.IsValid)
            {
                string Email = ConfigurationManager.AppSettings["Email"].ToString();
                string Emailto = EmailID;
                MailMessage mail = new MailMessage(Email, Emailto);
                mail.Subject = Subject;
                string mailmessage = "Name :"+ Name +"<br>"+ message;
                mail.Body = mailmessage;
                mail.IsBodyHtml = true;
                SmtpClient smtp = new SmtpClient();
                smtp.Send(mail);
                ViewBag.Message = "Email sent successfully";
            }
            return View();
        }
    }
}
