How to read the latest reply message in the mail retrieve from gmail by using IMAP in C#?

Question

_{Wednesday, August 7, 2019 12:51 PM}

How can I separate an email from its previous answer using IMAP and C#? I only want the latest reply

For example:

• Mail 1: Customer sends an email with the text: "Hello"
• Mail 2: I answer the email with text figures: "Yes?"
• Mail 3: The customer replies: "What are you doing?"

But when I collect these 3 mails with the phrase, GetBodyAsText I get the entire conversation from every mail - containing 1,2 and 3.

I only want mail 3 content : How can this be done?

Assuming both sides are using normal quoting procedures, the body of message #3 does actually include all the previous messages.  The body of the message might look like:

    What are you doing?

All of that literally is the body of message #3.  Now, if you want to strip out the quoting, you can eliminate the lines that start with ">".

Outlook uses a somewhat different standard, where the new text is on top, and the quoted message follows a horizontal line.  That's a bit trickier to parse.  And if one side uses the Outlook rule while another side uses the ">" rule, it gets almost impossible.

Hi RaviJunnur,

Thank you for posting here.

Based on your description, you want to get the latest reply message in the mail by using IMAP.

First, you could install-Package AE.Net.Mail.

Then, please try the following code.

            ImapClient ic = new ImapClient("imap.gmail.com", "useremail", "password",
                AuthMethods.Login, 993, true);
            ic.SelectMailbox("INBOX");
            int maxmium = ic.GetMessageCount();
            Console.WriteLine(maxmium);
            var list = ic.GetMessages(0, maxmium).ToList();
            var list1 = new List<MailMessage>();
            foreach (var item in list)
            {
                if(item.From.Address=="another's email")
                {
                    list1.Add(item);
                }
            }
            string m = list[list.Count - 1].Subject;
            Console.WriteLine(m);
            ic.Dispose();
