What code should I use to send email in C#?
I tried to find a specific code so that I could send an email from my website. And then I get an error: "The SMTP server requires a secure connection or the client was not authenticated. The server response was: 5.5.1 Authentication Required. Learn more at"
public void sendEmail(string toEmail, string subject, string emailBody)
{
string senderEmail = "My_Email";
string senderPassword = "My_Email_Password";
SmtpClient client = new SmtpClient("smtp.gmail.com", 587);
client.EnableSsl = true;
client.Timeout = 500000;
client.DeliveryMethod = SmtpDeliveryMethod.Network;
client.UseDefaultCredentials = false;
client.Credentials = new NetworkCredential(senderEmail, senderPassword);
MailMessage mailMessage = new MailMessage(senderEmail, toEmail, subject, emailBody);
mailMessage.IsBodyHtml = true;
mailMessage.BodyEncoding = UTF8Encoding.UTF8;
client.Send(mailMessage);
}
Do I need to use Google API??

Its a security issue, Gmail by default prevents access for your e-mail account from custom applications. You can set it up to accept the login from your application.
You need to go to security settings at the followig link https://www.google.com/settings/security/lesssecureapps and enable less secure apps. So that you will be able to login from all apps.
