How to send Forget password from asp.net website Free

Hi, Friends today i am going to make a Forget password Form application,so that any body can get your Forget password on your registered mail from ASP.NET website free. Previously i have made Registration and Login page Application,You can attach this Forget password page in this application.Here I have used gmail SMTP server for sending the User Name and respective password value to the registered email address.You can use your own server instead of gmail server for this purpose.It is full secure because you are sending the mail through gmail SMTP server.But for own Hosting you can use your SMTP server.The Students who are making any project they can use this service free because server space is more costly.   
There are some steps to implement this concept in your ASP.NET website.
Step 1:- First open your visual studio --> File  --> New  -->website -->ASP.NET EMPTY WEBSITE  -->OK -->Now open your Solution Explorer -->Add a web Form  -->Drag and Drop Label,Text Box and Button controls on the form as shown below:-

public partial class _Default : System.Web.UI.Page
{
    protected void Page_Load(object sender, EventArgs e)
    {

    }
    protected void Button1_Click(object sender, EventArgs e)
    {
     SqlConnection con = new SqlConnection(@"Data Source=.\;AttachDbFilename=|DataDirectory|\Database.mdf;Integrated Security=True;User Instance=True;");
     con.Open();
     SqlCommand cmd = new SqlCommand("SELECT username,password FROM emp Where email= '" +TextBox1.Text + "'", con);
     SqlDataAdapter da = new SqlDataAdapter(cmd);
     DataSet ds = new DataSet();
     da.Fill(ds);
     con.Close();
     if (ds.Tables[0].Rows.Count > 0)
     {
         MailMessage email = new MailMessage();
         email.From = new MailAddress(TextBox1.Text); //Enter sender email address
         email.To.Add(TextBox1.Text); //Destination Recipient e-mail address.
         email.Subject = "Your Forrget Password:";//Subject for your request
         email.Body = "Hi,<br/>Your Username is: " + ds.Tables[0].Rows[0]["username"] + "<br/><br/>Your Password is: " + ds.Tables[0].Rows[0]["Password"] + "<br/>";
         email.IsBodyHtml = true;
         //SMTP SERVER DETAILS
         SmtpClient smtpc = new SmtpClient("smtp.gmail.com");
         smtpc.Port = 587;
         smtpc.UseDefaultCredentials = false;
         smtpc.EnableSsl = true;

         smtpc.Credentials = new NetworkCredential(Label1.Text, Label2.Text);
         smtpc.Send(email);
         Label2.Text = "Your password has been sent to your email address";
     }
         else
         {
         Label3.Text="This email address is not exist in our Database try again";
