Connecting email server to my Contact page of web application in asp.net/c#

Question

Perhaps it is an easy question but I am new in developing in c#, asp.net. I am building a website and I have some troubles connecting the email server to my Contact page. I've been searching for a long time but I couldn't find a suitabe answer. My controller code is the following:

namespace SITEEXEMPLO.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("xoinas23@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("xoinas23@gmail.com", "xxxxx");
                // 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();
        }

And the HTML code is the following:

@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>

This works but not the way I want. By running this code, I insert the information and I receive it on the email inserted on the form, not the email in the code. I want the users to write their own email on the form, and by clicking the button I receive the information on my email. Can someone help me?

Answer 1

Unless I'm misunderstanding, I believe you want to send an email to xoinas23@gmail.com. To do so, change your code to be the following:

mail.To.Add("xoinas23@gmail.com");
mail.From = new MailAddress("xoinas23@gmail.com");

Right now, you are sending an email to the email address provided by the person submitting the form. With this change, you'll just be sending their information to yourself by using your email address.
