Rehber ASP.NET ve C# SMTP mail gönderme

ASP.NET ile SMTP mail göndermek için aşağıda yazdığım Class'tan faydalanabilirsiniz. ASP.NET'te mail ayarları için web.config'te ayarlama yapmanız gerekiyor.

[CODE title="ASP.NET için web.config"]<!-- Sizde appSettings varsa sadece içini almanız yeterli. -->

Bu da kodun sade hali konsol ve form uygulamalarınız için kullanabilirsiniz.
