I am using AE.NET to get mail from Gmail using IMAP. I am able to get the messages, however when I try iterate over the message attachments there are none. Returning message.Value.Attachments.Count() gives me 0. Please see my code below:

C#

using (ImapClient ic = new ImapClient("imap.gmail.com", "test*****@gmail.com", "******", ImapClient.AuthMethods.Login, 993, true))
               {
                   // Open a mailbox, case-insensitive
                   ic.SelectMailbox("INBOX");

                   // Get messages based on the flag "Undeleted()".
                   Lazy<MailMessage>[] messages = ic.SearchMessages(SearchCondition.Undeleted(), false);

                   int count = messages.Count();

                   Response.Write(count.ToString());

                   // Process each message
                   foreach (Lazy<MailMessage> message in messages)
                   {
                       MailMessage m = message.Value;
                       Response.Write("<br/>");
                       Response.Write(m.From.Address);
                       Response.Write("---");
                       Response.Write(m.Subject);
                       Response.Write("***");
                       Response.Write(m.MessageID);
                       Response.Write("%%%");
                       Response.Write(m.From.DisplayName);

                       if (m.Attachments.Count > 0)
                       {
                           // ExtractString(m.Subject, "(", ")");

                           foreach (Attachment attachment in m.Attachments)
                           {
                               string fileName = m.Subject + "_" + attachment.Filename;
                               attachment.Save(@"D:\DemoMail\" + fileName + Path.GetExtension(attachment.Filename));
                           }
                       }


                   }

               }

This code will be help full i had developed and tested vb version only just converted this code to c#, so i will post the vb code for reference. it includes snippets for saving attachments to selected folder and also for save cc and bcc in CSV format to a string variable:

VB Code

VB

Public Sub fetchMails()
          Dim imapClient As New Imap4Client()
          ' login to the mail
          Dim mailNumber As Integer = 10 'reading 10th mail
          Dim notYetProcessedBox As Mailbox = imapClient.SelectMailbox("Inbox")
          Dim msg As Message = notYetProcessedBox.Fetch.MessageObject(mailNumber)
          ' To read cc and bcc
          Dim mailCC As String = ""
          Dim mailBcc As String = ""
          Dim cc() As ActiveUp.Net.Mail.Address = msg.Cc.ToArray()
          Dim bcc() As ActiveUp.Net.Mail.Address = msg.Bcc.ToArray()
          For Each address As ActiveUp.Net.Mail.Address In cc
              mailCC &= address.ToString
          Next
          For Each address As ActiveUp.Net.Mail.Address In bcc
              mailBcc &= address.ToString
          Next
          ' For saving attachment
          If msg.Attachments.Count <> 0 Then
              If System.IO.Directory.Exists("../email_attachment/") = False Then
                  System.IO.Directory.CreateDirectory("../email_attachment/")
                  msg.Attachments.StoreToFolder("../email_attachment/")
              End If
          End If
      End Sub

C# Code

C#

public void fetchMails()
{
	Imap4Client imapClient = new Imap4Client();
	// login to the mail
	int mailNumber = 10;
	//reading 10th mail
	Mailbox notYetProcessedBox = imapClient.SelectMailbox("Inbox");
	Message msg = notYetProcessedBox.Fetch.MessageObject(mailNumber);
	// To read cc and bcc
	string mailCC = "";
	string mailBcc = "";
	ActiveUp.Net.Mail.Address[] cc = msg.Cc.ToArray();
	ActiveUp.Net.Mail.Address[] bcc = msg.Bcc.ToArray();
	foreach (ActiveUp.Net.Mail.Address address in cc) {
		mailCC += address.ToString;
	}
	foreach (ActiveUp.Net.Mail.Address address in bcc) {
		mailBcc += address.ToString;
	}
	// For saving attachment
	if (msg.Attachments.Count != 0) {
		if (System.IO.Directory.Exists("../email_attachment/") == false) {
			System.IO.Directory.CreateDirectory("../email_attachment/");
			msg.Attachments.StoreToFolder("../email_attachment/");
		}
	}
}
