This article will show you how you can implement forgot
password (password recovery) and send password in email in mvc5 & mvc6
using c#.net.
Some of my previous articles are as follows: Implement
Forgot Password (Password Recovery) and send password in Email in ASP.Net Using
C#, Contact
Us Form With Browse File Attachment in Asp.net C#, Contact
Us Form in MVC5 & MVC6 C#, Contact
Us Form in Asp.net C#, How
to Send Mail in MVC6 Using C# Code With Attachment, Send
Mail In MVC5 and MVC6 In C# Using Gmail, 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.
So for this article first we will create a new asp.net mvc
application and add a controller class file in it. After that create the view
and add the below code into the view.
@{
ViewBag.Title
= "Asp.net MVC: Implement Forgot
Password (Password Recovery) and send password in Email in MVC5 &
MVC6";
}
<script>
function Validate() {
var data = document.getElementById("txtEmailID").value;
if (data == "") {
alert("Please enter your email id.");
return false;
} else {
return true;
}
}
</script>
@using (Html.BeginForm("Index", "Forgotpassword"))
{
<div>
Forgot
Password:@Html.TextBox("EmailId", "", new { @style = "width:200px;",
@id = "txtEmailID" })
<input type="submit" value="Submit" onclick="javascript: return Validate();" /><br />
@if (ViewBag.Message == 1)
{
<span style="color:green;">Please check your email for account login detail.</span>
}
else if (ViewBag.Message == 0)
{
<span style="color:red;">Please provide a valid register email id.</span>
}
</div>
}

In above code I have added textbox control and a input Sutton
control to create the form. This form will request for user email id. In above I
have also applied and javascript validation to validate weather user have provided
any input or not. Now in above code textbox control name is important. By this
name we will be able to access the provided email id at controller end on
postback. After this lets check the controller code.
In this first I have created a function which will send the
email.
public string SendPassword(string password, string emailId, string name)
{
try
{
MailMessage mail
= new MailMessage();
mail.To.Add(emailId);
mail.From = new MailAddress("youremail
@gmail.com");
mail.Subject = "Your password for
account " + emailId;
string userMessage = "";
userMessage = userMessage + "<br/><b>Login
Id:</b> " + emailId;
userMessage = userMessage + "<br/><b>Passsword:
</b>" + password;
string Body = "Dear
" + name + ", <br/><br/>Login detail for your
account is a follows:<br/></br> " + userMessage + "<br/><br/>Thanks";
mail.Body = Body;
mail.IsBodyHtml = true;
SmtpClient smtp
= new SmtpClient();
smtp.Host = "smtp.gmail.com"; //SMTP Server Address of
gmail
smtp.Port = 587;
smtp.Credentials = new System.Net.NetworkCredential("youremail@gmail.com", "password");
// Smtp Email ID and Password For authentication
smtp.EnableSsl = true;
smtp.Send(mail);
return "Please check your email for account login
detail.";
}
catch
{
return "Error............";
}
}

Now check the httpget and post method.
[HttpGet]
public ActionResult
Index()
{
return View();
}
[HttpPost]
public ActionResult
Index(string
EmailId)
{
/*Create instance of entity model*/
NorthwindEntities objentity = new NorthwindEntities();
/*Getting data from database for email validation*/
var _objuserdetail = (from data in objentity.UserDetails
where data.EmailId ==
EmailId
select data);
if (_objuserdetail.Count()
> 0)
{
string status =
SendPassword(_objuserdetail.Password, _objuserdetail.EmailId,
_objuserdetail.Name);
ViewBag.Message = 1;
}
else
{
ViewBag.Message = 0;
}
return View();
}
|
In above code I have validated the user from data base table using entity framework. If we get
user detail on that case we will send the tail on the user email otherwise we
will throw error message.
Now check the complete code of controller.
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 ForgotpasswordController
: Controller
{
//
// GET: /Forgotpassword/
[HttpGet]
public ActionResult
Index()
{
return View();
}
[HttpPost]
public ActionResult
Index(string
EmailId)
{
/*Create instance of entity model*/
NorthwindEntities
objentity = new NorthwindEntities();
/*Getting data from database for email validation*/
var _objuserdetail = (from data in objentity.UserDetails
where data.EmailId ==
EmailId
select data);
if (_objuserdetail.Count()
> 0)
{
string status =
SendPassword(_objuserdetail.Password, _objuserdetail.EmailId,
_objuserdetail.Name);
ViewBag.Message = 1;
}
else
{
ViewBag.Message = 0;
}
return View();
}
public string SendPassword(string password, string emailId, string name)
{
try
{
MailMessage mail
= new MailMessage();
mail.To.Add(emailId);
mail.From = new MailAddress("youremail
@gmail.com");
mail.Subject = "Your password for
account " + emailId;
string userMessage = "";
userMessage = userMessage + "<br/><b>Login
Id:</b> " + emailId;
userMessage = userMessage + "<br/><b>Passsword:
</b>" + password;
string Body = "Dear " +
name + ", <br/><br/>Login
detail for your account is a follows:<br/></br> " + userMessage + "<br/><br/>Thanks";
mail.Body = Body;
mail.IsBodyHtml = true;
SmtpClient smtp
= new SmtpClient();
smtp.Host
= "smtp.gmail.com"; //SMTP Server Address of
gmail
smtp.Port = 587;
smtp.Credentials = new System.Net.NetworkCredential("youremail@gmail.com", "password");
// Smtp Email ID and Password For authentication
smtp.EnableSsl = true;
smtp.Send(mail);
return "Please check your email for account login
detail.";
}
catch
{
return "Error............";
}
}
}
}

Now we have done run the application to check the output.
First add an invalid email id.
Now provide a valid email id.
Now lets check the email .
