Trigger Email using C# | .NET Developers

INTRODUCTION

Sending an email from Web Application or Web Services are quite a common practise nowadays. Few common practices like notifying users, triggering errors, sending an update, sending a detailed report, etc. So there are different ways and different languages to trigger email, but today I will try to explain and share the code how you can trigger mail using the C# programming language.

I will try creating a console application and try to write a common method that can trigger email and that method can be reused later.

Step 1: Create a New Console App(.NET Framework)

Step 2: Create a .cs Page

Step 3: Start Writing Code -

        So as you can see senderEmailID and senderPassword we are storing in Web.Config (App.Config) and will fetch using ConfigurationManager.AppSettings[""] so that the first layer of data hiding can be done.

Note: 

• Library for ConfigurationManager: System.Configuration
• Library for SmtpClient: System.Net.Mail
• Library for UTF8Encoding: System.Text

Now I will show how to write the App.Config code -

Complete Code to trigger Email Service

        public bool SendEmail(string toEmail, string subject, string mailBody)

        {

            try

            {

                string senderEmailID = ConfigurationManager.AppSettings["EmailID"].ToString();

                string senderPassword = ConfigurationManager.AppSettings["Password"].ToString();

                SmtpClient sc = new SmtpClient("smtp.gmail.com", 587);

                sc.EnableSsl = true;

                sc.Timeout = 100000;

                sc.DeliveryMethod = SmtpDeliveryMethod.Network;

                sc.UseDefaultCredentials = false;

                sc.Credentials = new NetworkCredential(senderEmailID, senderPassword);

                MailMessage mm = new MailMessage(senderEmailID, toEmail, subject, mailBody);

                mm.IsBodyHtml = true;

                mm.BodyEncoding = UTF8Encoding.UTF8;

                sc.Send(mm);

                return true;

            }

            catch (Exception ex)

            {

                return false;

            }

        }
