HI,

In my project i asked to send the forgotten password of user to his mail account..
for that i asked email address to user and fetched the password from database according to email address field.

my code is below..

code for View..

<%@ Page Title="" Language="C#" MasterPageFile="~/Views/Shared/Site.Master" Inherits="System.Web.Mvc.ViewPage<TelerikLogin.Models.ViewModels.ForgotPassword>" %>

<asp:Content ID="Content1" ContentPlaceHolderID="TitleContent" runat="server">
    ForgotPassword
</asp:Content>

<asp:Content ID="Content2" ContentPlaceHolderID="MainContent" runat="server">

<h2>ForgotPassword</h2>
<script src="<%: Url.Content("~/Scripts/jquery.validate.min.js") %>" type="text/javascript"></script>
<script src="<%: Url.Content("~/Scripts/jquery.validate.unobtrusive.min.js") %>" type="text/javascript"></script>

<% using (Html.BeginForm("ForgotPassword", "Account", FormMethod.Post))
   { %>

   <%: Html.LabelFor(m => m.user_email_address) %>
   <%: Html.TextBox("user_email_address")%>
      <%: Html.ValidationSummary(true) %>

<input type="submit" value="Submit"/>

code for Model..

using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.ComponentModel.DataAnnotations;

namespace TelerikLogin.Models.ViewModels
{
    public class ForgotPassword
    {
        public int user_id { get; set; }
        public string user_login_name { get; set; }
        public string user_password { get; set; }

        [Required]
        [Display(Name="Email Address : ")]
        public string user_email_address { get; set; }
    }
}

code for Controller..

 public ActionResult ForgotPassword()
        {
            return View();
        }

        [HttpPost]
        public ActionResult ForgotPassword(string user_email_address)
        {
           
            SqlConnection conn = new SqlConnection(@"Data Source=.\SQLEXPRESS;AttachDbFilename=E:\MVC3\TelerikLogin\TelerikLogin\App_Data\Login.mdf;Integrated Security=True;User Instance=True");

            DataTable dt1 = new DataTable();
            
            string strQuery = string.Format("SELECT user_password FROM [user_master] WHERE user_email_address='{0}'",user_email_address);
           
  
          
            conn.Open();
        
            SqlDataAdapter da1 = new SqlDataAdapter(strQuery, conn);
            da1.Fill(dt1);
            
            LoginEntities3 le= new LoginEntities3();
          
           conn.Close();

// In below variable pwd i fetch the password...

            var pwd = from u in  new LoginEntities3().user_master
                       where u.user_email_address == user_email_address select u.user_password;


      

            if (dt1.Rows.Count > 0)
            {
                

                MailAddress mailfrom = new MailAddress("emailid@gmail.com");
                MailAddress mailto = new MailAddress(user_email_address);
                MailMessage newmsg = new MailMessage(mailfrom, mailto);

                newmsg.Subject = "Your Password";

// AND here i assign that variable to body

                newmsg.Body = pwd.ToString();

                

                SmtpClient smtps = new SmtpClient("smtp.gmail.com", 587);
                smtps.UseDefaultCredentials = false;
                smtps.Credentials = new NetworkCredential("emailid@gmail.com", "password");
                smtps.EnableSsl = true;
                smtps.Send(newmsg);
                

                return RedirectToAction("About", "Home");
            }
            

           return View();
        }

I have to send password in the body
so i assign variable pwd to msg.body
then it gave me an error of type casting so i use ToString method..
so it send an sql query instead of password..
:(

Any solution??
