So I’ve actually had to do this before for a project I was working on, and thought that I’d go ahead and post a brief example of how to accomplish it here.
This example sends a simple email to a single recipient by using GMail. Please note that the principle classes used (MailMessage, SmtpClient, and NetworkCredential) are only available in the .NET Library 2.0 or later. For .NET < 2.0 you’ll want to see the System.Web namespace.
// Create the mail object. System.Net.Mail.MailMessage msgMail = new System.Net.Mail.MailMessage( "TestEmail@mel-gree.com", // FROM "firstname.lastname@example.org" // TO ); // Set the subject of the message msgMail.Subject = "Hello from C#"; // Set that the body of this message will be HTML msgMail.IsBodyHtml = true; // Set the body of the email. Since I specified that // I'm using HTML this will be fully qualified HTML/XHTML msgMail.Body = "" + "" + " <h4>Hello There!</h4> " + " You've been selected to receive this email." + "Congratulations! " + "" + ""; // Now I'll create an SMTP object to send the message // by means of a SMTP server. System.Net.Mail.SmtpClient smtp = new System.Net.Mail.SmtpClient( "smtp.gmail.com", // Server address 587 // Server port ); // GMail uses SSL smtp.EnableSsl = true; // GMail uses authentication smtp.UseDefaultCredentials = false; smtp.Credentials = new System.Net.NetworkCredential ( "email@example.com", // Account Name "MyPassword" // Account Password ); // Finally, send the message! smtp.Send(msgMail);
