Hi Lili, Try like use namespace System.Net.Mail private void button1_Click(object sender, EventArgs e) { try { MailMessage mail = new MailMessage(); //System.Net.Mail mail.From = new MailAddress("mail.PSP@acd.com"); mail.To.Add("test.aes@gmail.com"); mail.Subject = "Test-Mail From WindowsForm"; mail.Body =" Hello World "; mail.IsBodyHtml = true; SmtpClient sc = new SmtpClient("smtp.gmail.com"); sc.Send(mail); MessageBox.Show("Your e-mail is sent suuccessfully!", "Message Sent", MessageBoxButtons.OK, MessageBoxIcon.Information); } catch (Exception ex) { MessageBox.Show(ex.Message); } }
