.NET C# 使用S22.Imap.dll接收郵件 并且指定收取的文件夾的未讀郵件，并且更改未讀準態

   string host = Conf.ConfigInfo.POP_Host;                int port = Conf.ConfigInfo.POP_Port;                string username =Conf.ConfigInfo.MailName;                string passWord = Conf.ConfigInfo.MailPassword;                using (S22.Imap.ImapClient client = new S22.Imap.ImapClient(host, port, username, password))                {                    var unseen = client.Search(SearchCondition.Unseen(), Conf.ConfigInfo.SelectFolder);                    if (unseen == null || unseen.Count() == 0)                    {                        Console.WriteLine(string.Format("==============>沒有新郵件！"));                        return;                    }                    Console.WriteLine(string.Format("==============>開始檢測"));                    foreach (uint uid in unseen)                    {                        var msg= client.GetMessage(uid,true,Conf.ConfigInfo.SelectFolder);                        try                        {                          Fetchcallback(msg, uid);                          client.SetMessageFlags(uid,Conf.ConfigInfo.SelectFolder,MessageFlag.Seen);                        }                        catch (Exception ex)                        {                            throw ex;                        }                    }               }

var msg= client.GetMessage(uid,true,Conf.ConfigInfo.SelectFolder);

注：默認MSG 是獲取的TEXT 郵件內容要獲取HTML內容代碼如下

var dataStream = msg.AlternateViews[0].ContentStream; byte[] byteBuffer = new byte[dataStream.Length]; string altbody = msg.BodyEncoding.GetString(byteBuffer, 0, dataStream.Read(byteBuffer, 0, byteBuffer.Length));
