Before
implement this first design one table UserInfo
in your database like as shown below
Column Name
|
Data Type
|
Allow Nulls
|
UserId
|
int
(Set Identity=true)
|
No
|
UserName
|
varchar(50)
|
Yes
|
Email
|
varchar(125)
|
Yes
|
Location
|
varchar(50)
|
Yes
|
Once
table design complete enter some dummy for our example like as shown below
UserInfo
 |
Now
we are going to use our gmail account credentials to send mail for that first
you need to enable POP enable option in your Gmail account for that you need to
open your gmail account and go to Settings-->Forwarding and
POP/IMAP
After that design your aspx page
like this
<html xmlns="http://www.w3.org/1999/xhtml">
<head id="Head1"
runat="server">
<title>Code to recover forgot password in asp.net using C# and
VB.NET</title>
<style type="text/css">
.Button
{
background-color :#FF5A00;
color: #FFFFFF;
font-weight: bold;
margin-right: 2px;
padding: 4px 20px 4px 21px;
}
</style>
</head>
<body>
<form id="form1"
runat="server">
<div>
<table cellspacing="2" cellpadding="2" border="0">
<tr><td></td><td><b>Forgot Password Example</b></td></tr>
<tr><td><b>Enter Your Email:</b></td><td><asp:TextBox ID="txtEmail" runat="server" /></td></tr>
<tr><td></td><td><asp:button ID="btnSubmit"
Text="Submit" runat="server" onclick="btnSubmit_Click" CssClass="Button"/></td></tr>
<tr><td colspan="2" style=" color:red"><asp:Label ID="lbltxt"
runat="server"/></td></tr>
</table>
</div>
</form>
</body>
</html>
|
After
that add following namespaces in your codebehind
C# Code
using System;
using System.Data;
using System.Data.SqlClient;
using System.Net.Mail;
|
After
that write the following code in button click
protected void
btnSubmit_Click(object sender, EventArgs e)
{
try
{
DataSet ds = new DataSet();
using (SqlConnection
con = new SqlConnection("Data Source=SureshDasari;Integrated
Security=true;Initial Catalog=MySampleDB"))
{
con.Open();
SqlCommand cmd = new SqlCommand("SELECT
UserName,Password FROM UserInfo Where Email= '" +
txtEmail.Text.Trim() + "'",
con);
SqlDataAdapter da = new SqlDataAdapter(cmd);
da.Fill(ds);
con.Close();
}
if(ds.Tables[0].Rows.Count>0)
{
MailMessage Msg = new MailMessage();
// Sender e-mail address.
Msg.From = new
MailAddress(txtEmail.Text);
// Recipient e-mail address.
Msg.To.Add(txtEmail.Text);
Msg.Subject = "Your
Password Details";
Msg.Body = "Hi,
<br/>Please check your Login Detailss<br/><br/>Your
Username: " + ds.Tables[0].Rows[0]["UserName"]
+ "<br/><br/>Your Password:
" + ds.Tables[0].Rows[0]["Password"]
+ "<br/><br/>";
Msg.IsBodyHtml = true;
// your remote SMTP server IP.
SmtpClient smtp = new SmtpClient();
smtp.Host = "smtp.gmail.com";
smtp.Port = 587;
smtp.Credentials = new
System.Net.NetworkCredential ("yourusername@gmail.com", "yourpassword");
smtp.EnableSsl = true;
smtp.Send(Msg);
//Msg = null;
lbltxt.Text = "Your
Password Details Sent to your mail";
// Clear the textbox valuess
txtEmail.Text = "";
}
else
{
lbltxt.Text = "The
Email you entered not exists.";
}
}
catch (Exception
ex)
{
Console.WriteLine("{0}
Exception caught.", ex);
}
}
}
