Issue with SmtpClient in sending GMAIL Message

Hello Experts,

I am trying to send Message from my GMAIL account via C# code.

I could able to send it via classic methos i.e. by using 'System.Web.Mail.SmtpMail.Send(Mail)'. Find the attachement - "Working-Copy.JPG".

But I couldn't able to send GMAIL message from C# code by using System.Net.Mail.SmtpClient'.

I tried with two ways:

1) By Routine Procedure. Find the attachment - "TriedWithThisToo.JPG".

2) By using OpenPOP3 API. Find the attachment - "OpenPop3.JPG".

I want to send GMAIL message by using SmtpClient only for my project.

Any help would be grateful.

Cheers

Are you referring to OpenPop.NET 2.0.5 as found on sourceforge?

Why don't you just use the working code as you don't need POP3 just SMTP?
using System;
using System.Linq;
using System.Net;
using System.Net.Mail;

namespace pop3test_ee
{    class Program
    {
       static void Main(string[] args)
        {
            var t = new MySend();
            t.test1();
            Console.ReadKey();

        }
    }
    class MySend
    {
        public void test1()
        {
            try
            {
                SmtpClient client = new SmtpClient("smtp.gmail.com", 587);
                client.EnableSsl = true;
                client.Timeout = 100000;
                client.DeliveryMethod = SmtpDeliveryMethod.Network;
                client.UseDefaultCredentials = false;
                client.Credentials = new NetworkCredential("nobody@gmail.com", "password");
                MailMessage msg = new MailMessage("From Address<nobody@gmail.com>", "To Address <nobody@techsupport4me.com>", "Test Subject With Names", "Test Body With Names");
                client.Send(msg);
                System.Console.WriteLine("Successfully Sent Message");
            }
            catch (Exception ex)
            {
                System.Console.WriteLine(ex.Message);
            }
        }
    }
}

Thanks David your code has worked too.

But the main issue why i am opting to go for OpenPop3 API is...

In my project, I need to read new messages from client and need to REPLY to client message with ATTACHMENT.

Please let me know if I can achieve REPLY TO and ATTACHMENT with your above code
