using System;
using System.Net.Mail;
using System.Net.Mime;
using System.IO;

namespace EmailAttachmentExample
{
    class Program
    {
        static void Main()
        {
            // Sender's email address and password
            string senderEmail = "[email protected]";
            string senderPassword = "your-email-password";

            // Recipient's email address
            string recipientEmail = "[email protected]";

            // Create a new MailMessage
            MailMessage mail = new MailMessage();

            // Set the sender and recipient addresses
            mail.From = new MailAddress(senderEmail);
            mail.To.Add(recipientEmail);

            // Set the subject and body of the email
            mail.Subject = "Multiple Attachments Example";
            mail.Body = "Please find attached multiple PDF files.";

            // Attach the first PDF file
            string pdfFilePath1 = @"C:\path\to\your\first\file.pdf";
            Attachment attachment1 = new Attachment(pdfFilePath1, MediaTypeNames.Application.Pdf);
            mail.Attachments.Add(attachment1);

            // Attach the second PDF file
            string pdfFilePath2 = @"C:\path\to\your\second\file.pdf";
            Attachment attachment2 = new Attachment(pdfFilePath2, MediaTypeNames.Application.Pdf);
            mail.Attachments.Add(attachment2);

            // Create and configure the SMTP client
            SmtpClient smtpClient = new SmtpClient("smtp.your-email-provider.com");
            smtpClient.Port = 587;
            smtpClient.Credentials = new System.Net.NetworkCredential(senderEmail, senderPassword);
            smtpClient.EnableSsl = true;

            try
            {
                // Send the email
                smtpClient.Send(mail);
                Console.WriteLine("Email sent successfully!");
            }
            catch (Exception ex)
            {
                Console.WriteLine($"Error sending email: {ex.Message}");
            }
            finally
            {
                // Dispose of attachments and MailMessage
                attachment1.Dispose();
                attachment2.Dispose();
                mail.Dispose();
            }
        }
    }
}

You can send multiple attachments in an email in ASP.NET by adding multiple Attachment objects to the MailMessage instance. Here's an example of how you can modify your code to attach multiple PDF files to an email

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

// Create a MailMessage object
MailMessage mail = new MailMessage();

// Set the sender, recipient, subject, and body
mail.From = new MailAddress("[email protected]");
mail.To.Add("[email protected]");
mail.Subject = "Your Subject";
mail.Body = "Your email body";

// Attach the first PDF
Attachment attachment1 = new Attachment("path_to_first_pdf.pdf", MediaTypeNames.Application.Pdf);
mail.Attachments.Add(attachment1);

// Attach the second PDF
Attachment attachment2 = new Attachment("path_to_second_pdf.pdf", MediaTypeNames.Application.Pdf);
mail.Attachments.Add(attachment2);

// Set up the SMTP client and send the email
SmtpClient smtpClient = new SmtpClient("your_smtp_server");
smtpClient.Credentials = new NetworkCredential("your_username", "your_password");
smtpClient.Send(mail);
