How Can I Send Emails Through SSL SMTP with the .NET Framework?

To send emails through an SSL SMTP server on port 465 using the .NET Framework, utilize the following code snippet, which demonstrates how to send an email using GMail's SSL/465 configuration:

<code class="csharp">using System.Web.Mail;
using System;

public class MailSender
{
    public static bool SendEmail(
        string pGmailEmail, 
        string pGmailPassword, 
        string pTo, 
        string pSubject,
        string pBody, 
        System.Web.Mail.MailFormat pFormat,
        string pAttachmentPath)
    {
        try
        {
            System.Web.Mail.MailMessage myMail = new System.Web.Mail.MailMessage();
            myMail.Fields.Add
                ("http://schemas.microsoft.com/cdo/configuration/smtpserver",
                              "smtp.gmail.com");
            myMail.Fields.Add
                ("http://schemas.microsoft.com/cdo/configuration/smtpserverport",
                              "465");
            myMail.Fields.Add
                ("http://schemas.microsoft.com/cdo/configuration/sendusing",
                              "2");

            myMail.Fields.Add
                ("http://schemas.microsoft.com/cdo/configuration/smtpauthenticate","1");

            myMail.Fields.Add
                ("http://schemas.microsoft.com/cdo/configuration/sendusername",
                    pGmailEmail);
            myMail.Fields.Add
                ("http://schemas.microsoft.com/cdo/configuration/sendpassword",
                     pGmailPassword);
            myMail.Fields.Add
                ("http://schemas.microsoft.com/cdo/configuration/smtpusessl",
                     "true");
            myMail.From = pGmailEmail;
            myMail.To = pTo;
            myMail.Subject = pSubject;
            myMail.BodyFormat = pFormat;
            myMail.Body = pBody;
            if (pAttachmentPath.Trim() != "")
            {
                MailAttachment MyAttachment = 
                        new MailAttachment(pAttachmentPath);
                myMail.Attachments.Add(MyAttachment);
                myMail.Priority = System.Web.Mail.MailPriority.High;
            }

            System.Web.Mail.SmtpMail.SmtpServer = "smtp.gmail.com:465";
            System.Web.Mail.SmtpMail.Send(myMail);
            return true;
        }
        catch (Exception ex)
        {
            throw;
        }
    }
}</code>

By setting the appropriate field values, including SMTP host, port, and TLS settings, you can configure the email setup for various SMTP providers. Note that minor adjustments may be necessary to ensure compatibility with different providers.
