IMAP getting Response issue

Question

Iam working on IMAP, reading mail content I got twice or third times of same mails content.

I had check out different different scenario so I comes to know Response() was gives me repeatitive content.

I am passing Command like this.

                byte[] commandBytes = System.Text.Encoding.ASCII.GetBytes(("$ UID FETCH " + index + " (BODY[HEADER.FIELDS (SUBJECT FROM DATE)])" + "\r\n").ToCharArray());
        _imapNs.Write(commandBytes, 0, commandBytes.Length);
        _imapNs.Flush();
        string strMsg = Response();

my member of Stream and TcpClient is.

private TcpClient _imapClient;
private Stream _imapNs;

and my Response method is here.

private string Response()
{
    byte[] data = new byte[_imapClient.ReceiveBufferSize];
    int ret = _imapNs.Read(data, 0, data.Length);
    return Encoding.ASCII.GetString(data);
}

once I had check this complete cycle then I comes to knows the Response() method gives me repeatitive content so is there any solution for that.....

Thanks...!!

Which language are you using? C#? – Jaco Pretorius Feb 23 '11 at 13:26 — Jaco Pretorius, Feb 23 '11 at 13:26

There is no way your code will work.

You have assumed that the server response is smaller than _imapClient.ReceiveBufferSize. Why?

Server response may be 50 MB long. There is no way you'll be able to read it with the single call to Stream.Read method.

Sorry to say but it's working some time's it give me repeatitive content. _imapClient.ReceiveBufferSize is the Fix size,I dont Know whether that would be the problem or not. – Jitendra Jadav Feb 23 '11 at 18:14
Well if it's working sometimes it is **NOT ** working. What happens if the response is 2025 bytes long and your buffer size (_imapClient.ReceiveBufferSize) is e.g. 1024? You need to use a loop over Read method. – Pawel Lesnikowski Feb 24 '11 at 11:04

I would recommend that you use one of the many libraries available for C# (I'm assuming that's what you're using due to the syntax of your example - you didn't specify).

Take a look at the existing StackOverflow questions.

ok, but our requirement is not match for this so we need to customize the IMAP Client. – Jitendra Jadav Feb 23 '11 at 18:15
