c# - 使用C#在电子邮件中添加多个附件

Question

如何使用 C# 在电子邮件中附加多个文件。

        MailMessage mail = new MailMessage();
        SmtpClient SmtpServer = new SmtpClient("smtp.gmail.com");

        //get the userID, Pass
        userID= register.userName;
        password = register.pass;


        string aa=txtTo.Text;
        mail.From = new MailAddress(userID);
        mail.To.Add(aa);
        mail.Subject = txtsubject.Text;
        mail.Body = txtComments.Text;

        //Attach file
        mail.Attachments.Add(new Attachment(txtAttachments.Text.ToString()));       
        SmtpServer.Port = 587;
        SmtpServer.UseDefaultCredentials = false;
        SmtpServer.Credentials = new System.Net.NetworkCredential(userID, password);
        SmtpServer.EnableSsl = true;
        SmtpServer.Send(mail);
        MessageBox.Show("Email sent successfully");
        this.Cursor = Cursors.Default;

        //close the page
        Email email = new Email();
        email.Close();

此代码仅用于附加一个文件。我如何在 c# 2008 中附加多个文件？？？ 请给我解决方案。
