Feedback form example in ASP.Net C#

Dear viewer’s I will show how to create simple feedback from in ASP.Net C #. For implementing Email sending we have to need to import System.Net.Mail namespace in our page codebehind part .Now we will use two classes one is MailMessage and another is SmtpClient. MailMessage class is used for adding content of the mail such as name,subjct,email, and body content. SmtpClient is used for sending mail using through SMTP server.
