email grom web

I have created a simple web email that consists of two Textbox’s, one for the send to email address and a one for a message. The code works. I want to delete the Message Textbox and add multiple Textbox’s for Address, City, State, ZIP, and Phone Number. How can I do that? The following is my code:



<script language="C#" runat="server">

protected void Page_Load(object sender, EventArgs e)

{

}

protected void sendEmailButton_Click(object sender, EventArgs e)

{

MailMessage mail = new MailMessage();

mail.From = new MailAddress("[email protected]");

mail.Subject = "Personal Data" ;

mail.Body = txtMessage.Text;

mail.To.Add(txtEmail.Text);

SmtpClient smtp = new SmtpClient("smtp.MervNorton.com");

NetworkCredential credential = new NetworkCredential("[email protected]", "Merv@411");

smtp.Credentials = credential;

smtp.Send(mail);

Response.Write("Message was sent to " + mail.To + " at " + DateTime.Now);

}

</script>
