C# 操作.eml文件

前段时间做了个关于邮件的东西，记录一下如何解析和保存eml文件的。    

    /// <summary>        /// 解析eml        /// </summary>        private void AnalyzeEmlFile()        {        //    CDO.Message oMsg = new CDO.Message();        //    ADODB.Stream stm = null;        //    //读取EML文件到CDO.MESSAGE        //    try        //    {        //        stm = new ADODB.Stream();        //        stm.Open(System.Reflection.Missing.Value,        //        ADODB.ConnectModeEnum.adModeUnknown,        //        ADODB.StreamOpenOptionsEnum.adOpenStreamUnspecified,        //        "", "");        //        stm.Type = ADODB.StreamTypeEnum.adTypeBinary;//二进制方式读入        //        stm.LoadFromFile(emlpath); //将EML读入数据流        //        oMsg.DataSource.OpenObject(stm, "_stream"); //将EML数据流载入到CDO.Message

        //    }        //    catch (IOException ex)        //    {        //        using (StreamWriter writer = new StreamWriter(GlobalConstants.MailLogPath, true))        //        {        //            writer.WriteLine("解析eml文件出现异常" + DateTime.Now + "/n" + ex.Message);        //            writer.Close();        //        }        //    }        //    finally        //    {        //        stm.Close();        //    }        }

 

        /// <summary>        /// 将mailmessage保存为.eml文件        /// </summary>        /// <param name="msg">待保存的具有内容的MailMessage</param>        /// <param name="emlFileAbsolutePath">保存后的eml文件的路径</param>        static void SaveToEml(MailMessage msg, string emlFileAbsolutePath)        {            //const BindingFlags flags = BindingFlags.Instance | BindingFlags.NonPublic | BindingFlags.FlattenHierarchy;            //using (MemoryStream ms = new MemoryStream())            //{            //    Assembly assembly = typeof(System.Net.Mail.SmtpClient).Assembly;            //    Type tMailWriter = assembly.GetType("System.Net.Mail.MailWriter");            //    object mailWriter = Activator.CreateInstance(tMailWriter, flags, null, new object[] { ms }, CultureInfo.InvariantCulture);            //    msg.GetType().GetMethod("Send", flags).Invoke(msg, new object[] { mailWriter, true });            //    File.WriteAllText(emlFileAbsolutePath, System.Text.Encoding.Default.GetString(ms.ToArray()), System.Text.Encoding.Default);            //}        }

第二种方法保存.eml(缺陷是保存的文件名为随机的guid )

 //smtpClient.EnableSsl = false;                        // smtpClient.PickupDirectoryLocation = mailPath;//要保存的路径                        //smtpClient.DeliveryMethod = SmtpDeliveryMethod.SpecifiedPickupDirectory;
