Usage Example

Here's a basic example of how to send an email using the System.Net.Mail namespace:

using System;
using System.Net;
using System.Net.Mail;

public class EmailSender
{
    public static void SendTestEmail()
    {
        try
        {
            MailMessage mail = new MailMessage();
            mail.From = new MailAddress("sender@example.com");
            mail.To.Add(new MailAddress("recipient@example.com"));
            mail.Subject = "Test Email from .NET";
            mail.Body = "This is a test email sent using the System.Net.Mail namespace.";
            mail.IsBodyHtml = false;

            SmtpClient smtpClient = new SmtpClient("smtp.example.com");
            smtpClient.Port = 587;
            smtpClient.EnableSsl = true;
            smtpClient.UseDefaultCredentials = false;
            smtpClient.Credentials = new NetworkCredential("sender@example.com", "your_password");

            smtpClient.Send(mail);
            Console.WriteLine("Email sent successfully!");
        }
        catch (Exception ex)
        {
            Console.WriteLine($"Error sending email: {ex.Message}");
        }
    }
}
