C#

So, I am trying to send mail with SMTP from my Windows Form Porject. It perfectly works for hotmail(""smtp.live.com"") but I cann't make it work with gmail. Here's my Code:

public static void sendMailGmail(string from, string to, string subject, string text, string password)
        {
            MailMessage mail = new MailMessage(from, to, subject, text);
            SmtpClient client = new SmtpClient("smtp.gmail.com");
            client.Port = 587;
            client.EnableSsl = true;
            
            client.DeliveryMethod = SmtpDeliveryMethod.Network;
            client.UseDefaultCredentials = false;
            client.Credentials = new System.Net.NetworkCredential(from, password);
            try
            {
                client.Send(mail);
                MessageBox.Show("Mesage has benn sant&quot");
            }
            catch (Exception ex)
            {
                MessageBox.Show("Failure while sending message&quot");
                MessageBox.Show(ex.Message);
            }
        }

So, where I am making a mistake ?
