C # Mail send and receive implementation code

Send mail
Method One: Use System.Web.Mail to name empty #region Send message: This method fails

protected void sendfailed () {System.Web.Mail.MailMessage mail = new System.Web.Mail.MailMessage (); mail. from = "test@ gmail.com"; Mail. to = "test@ gmail.com"; Mail. Subject = "for Test"; Mail. priority = System.Web.Mail.MailPriority.Normal; Mail. bodyencoding = Encoding.default; Mail. BodyFormat = mailformat.html; Mail. Body = "This is a email!<input type= ' button ' value= ' OK '/>"; Mail. Fields.Add ("Http://schemas.microsoft.com/cdo/configuration/smtpauthenticate", "1"); Basic Authentication mail. Fields.Add ("Http://schemas.microsoft.com/cdo/configuration/sendusername", "Test"); Set your username here mail. Fields.Add ("Http://schemas.microsoft.com/cdo/configuration/sendpassword", "* * *"); Set your password here mail. Fields.Add ("Http://schemas.microsoft.com/cdo/configuration/smtpserver", "smtp.gmail.com"); Mail. Fields.Add ("Http://schemas.microsoft.com/cdo/configuration/smtpserverport", "587"); Mail. Fields.Add ("Http://schemas.microsoft.com/cdo/configuration/smtpusessl", "true"); SmtpmAil. SmtpServer = "smtp.gmail.com"; Smtpmail.send (mail); } #endregion间 (This method I have not successfully tested)

Method Two: Use the System.Net.Mail namespace (this method tests successfully)
I use Gmail's mailbox, and he provides a free SMTP service, before trying several mailboxes are unsuccessful. Gmail's SMTP service must be SSL-encrypted before it can be verified successfully.

#region Send mail: This method works protected void Sendsuccess () {System.Net.Mail.MailMessage message = new System.Net.Mail.MailMessage ( ); Message. from = new MailAddress ("test@gmail.com", "someone");//Must be a mail server message that provides the SMTP service. To.add (New MailAddress ("test@yahoo.com.cn")); Message. Subject = "Test Mail"; Message. Cc. ADD (New MailAddress ("test@126.com")); Message. Bcc.add (New MailAddress ("test@126.com")); Message. Isbodyhtml = true; Message. bodyencoding = System.Text.Encoding.UTF8; Message. Body = "Mail sending test"; Message. priority = System.Net.Mail.MailPriority.High; SmtpClient client = new SmtpClient ("smtp.gmail.com", 587); The port client used by the 587;//gmail. Credentials = new System.Net.NetworkCredential ("test@gmail.com", "password"); Here is the application email and password client. Enablessl = true; Must be encrypted by SSL try {client. Send (message); Response.Write ("The message has been successfully sent to" + message.) To.tostring () + "<br>"); } catch (Exception ee) {Response.Write (EE. Message + "<br>"/* + EE. innerexception.message*/); }} #endregion

Mail receive
I use lumisoft.net this open-source project, but also from a netizen where to see the download address, and then read the code himself, wrote a simple way to receive. Start by referencing the DLL files in your code in the Relrease directory into your project.

Using LumiSoft.Net.POP3.Client; Using LumiSoft.Net.Mail; ... public ilist<mail_message> receivemail () {ilist<mail_message> maillist = new List<mail_message> () ; using (pop3_client client = new Pop3_client ()) {client. Connect ("pop.gmail.com", 995,true); Client. Authenticate ("Zw.seaman", "Zw_seaman", false); Pop3_clientmessagecollection coll = client. Messages; for (int i = 0; i < Coll. Count; i++) {Pop3_clientmessage message = Coll[i]; mail_message mm = Mail_message.parsefrombyte (Coll[i]. Messagetobyte ()); Maillist.add (mm); }} return maillist; } protected void Page_Load (object sender, EventArgs e) {ilist<mail_message> maillist = new Zmail.mail (). Receivemail (); foreach (Mail_message Mail in maillist) {StringBuilder sb = new StringBuilder (); sb. Append (mail. From.tostring ()). Append ("Sent to"); Sb. Append (mail. To.tostring ()). Append ("<br/>"); Sb. Append (mail. Subject). Append ("<br/>"); Sb. Append (mail. Bodyhtmltext). Append ("
