I want to send email. What i have already done is this

System.Web.Mail.MailMessage obj = new System.Web.Mail.MailMessage();
obj.To = this.txtTo.Text.Trim();
obj.From = this.txtFrom.Text.Trim();
obj.Bcc = this.txtBcc.Text.Trim();
obj.Subject = this.txtSubject.Text.Trim();
obj.Body = this.txtMessage.Text.Trim();
System.Web.Mail.SmtpMail.SmtpServer = this.txtEmailServer.Text.Trim();
MessageBox.Show("mailed successfully", "Message");
