نکته های مفید و حرفه ای در سی شارپ C#

[ali]

از این متد برای ارسال ایمیل در سی شارپ C# استفاده می شود. در این روش از SMTP استفاده شده است:

کد:

public void UDF_Authenticate(String Str_EmailTo)
        {
            //create the mail message
            MailMessage mail = new MailMessage();
            String Str_PassWord = GetUniqueKey(5);
            //set the addresses
            mail.From = new MailAddress("info@a00b.com");
            mail.To.Add(Str_EmailTo.Trim());

            //set the content
            mail.Subject = "Password Information";
            mail.Body = "<div style=\"direction: ltr;\"><span style=\"font-size: large;\"><u><em><strong>&nbsp;Your New PassWord:</u> " + Str_PassWord.Trim() + " </strong></em></span></div><div style=\"direction: ltr;\"><a href=\"http://www.a00b.com\"><span style=\"font-size: large;\"><u><em><strong>www.a00b.com</strong></em></u></span></a></div>";
            mail.IsBodyHtml = true;
            //send the message
            SmtpClient smtp = new SmtpClient("mail.a00b.com");
            smtp.Port = 25;

            //to authenticate we set the username and password properites on the SmtpClient
            smtp.Credentials = new NetworkCredential("info@a00b.com", "**********"); // در این محل اطلاعات کاربری ایمیل قرار می گیرد
            smtp.Send(mail);
        }

        private String GetUniqueKey(int maxSize)
        {
            char[] chars = new char[62];
            chars =
            "ABCDEFGHJKLMNPQRSTUVWXYZ123456789".ToCharArray();
            byte[] data = new byte[1];
            RNGCryptoServiceProvider crypto = new RNGCryptoServiceProvider();
            crypto.GetNonZeroBytes(data);
            data = new byte[maxSize];
            crypto.GetNonZeroBytes(data);
            StringBuilder result = new StringBuilder(maxSize);
            foreach (byte b in data)
            {
                result.Append(chars[b % (chars.Length)]);
            }
            return result.ToString();
        }

و این هم یک متد دیگه که کمی کاملتره:

کد:

try
{

   SmtpClient mySmtpClient = new SmtpClient("my.smtp.exampleserver.net");

    // set smtp-client with basicAuthentication
    mySmtpClient.UseDefaultCredentials = false;
   System.Net.NetworkCredential basicAuthenticationInfo = new
      System.Net.NetworkCredential("username", "password");
   mySmtpClient.Credentials = basicAuthenticationInfo;

   // add from,to mailaddresses
   MailAddress from = new MailAddress("test@example.com", "TestFromName");
   MailAddress to = new MailAddress("test2@example.com", "TestToName");
   MailMessage myMail = new System.Net.Mail.MailMessage(from, to);

   // add ReplyTo
   MailAddress replyto = new MailAddress("reply@example.com");
   myMail.ReplyTo = replyto;

   // set subject and encoding
   myMail.Subject = "Test message";
   myMail.SubjectEncoding = System.Text.Encoding.UTF8;

   // set body-message and encoding
   myMail.Body = "<b>Test Mail</b><br>using <b>HTML</b>.";
   myMail.BodyEncoding = System.Text.Encoding.UTF8;
   // text or html
   myMail.IsBodyHtml = true;

   mySmtpClient.Send(myMail);
}

catch (SmtpException ex)
{
  throw new ApplicationException
    ("SmtpException has occured: " + ex.Message);
}
catch (Exception ex)
{
   throw ex;
}
