i m using c# instead of vb n also......i will really appreciate if u provide an example code for explaination

using System.Net.Mail;

MailMessage msgMail = new MailMessage();
SmtpClient smtpMail = new SmtpClient();
msgMail.To.Add(New MailAddress(here you need to use your textbox.Text));
msgMail.From = New MailAddress(set your email or any specific email);
msgMail.Subject = "set your subject line";
msgMail.IsBodyHtml = True;
smtpMail.Host = "set your email host address";
smtpMail.Send(msgMail);

this is the C# working code. MailMessage is class which is used to construct an email message and send it using smtpclient.
