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);

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/>";

SmtpClient smtp = new SmtpClient();
smtp.Host = "smtp.gmail.com";
smtp.Port = 587;
smtp.Credentials = new System.Net.NetworkCredential
("yourusername@gmail.com", "yourpassword");
