How can i send EMail by using my local machine in C#

Hello Uday,

If I understand it correctly, gmail no longer allows sending mail the way to you have described.

Better use sendgrid that microsoft recommends.

Hello Paul,

Try Following

using System;
using System.Collections.Generic;
using System.Text;
using System.Net.Mail;
using System.Net;

class Program
{
    static void Main(string[] args)
    {
        Console.WriteLine("Mail To");
        MailAddress to = new MailAddress(Console.ReadLine());

        Console.WriteLine("Mail From");
        MailAddress from = new MailAddress(Console.ReadLine());

        MailMessage mail = new MailMessage(from, to);

        Console.WriteLine("Subject");
        mail.Subject = Console.ReadLine();

        Console.WriteLine("Your Message");
        mail.Body = Console.ReadLine();

        SmtpClient smtp = new SmtpClient();
        smtp.Host = "smtp.gmail.com";
        smtp.Port = 587;

        smtp.Credentials = new NetworkCredential(
            "[email protected]", "password");
        smtp.EnableSsl = true;
        Console.WriteLine("Sending email...");
        smtp.Send(mail);
    }
}

You can send it from your local system using some SMTP account only. A better and more convenient way is to use a Gmail account which is also free if you want to do it for testing.
