如何用CDO得到eml邮件的信息和附件内容
google了很多.在CSDN找到个比较考谱的帖, 但是弄到C#下面时候有问题. 尤其是不能解析elm中base64的附件

现在问题就是如果可以把base64的stream提取出来, 然后可以让我用decoder base64的方法转换成文件,

谢谢大家, 如果你有更好的解决方法, 不妨说说. 谢谢.

我的code:

protected void Page_Load(object sender, EventArgs e)
        {
            CDO.Message oMsg = new CDO.Message();

            string emlFilePath = @"c:\test.eml";
            ADODB.Stream stm = new ADODB.Stream();
            stm.Open(System.Reflection.Missing.Value,
                     ADODB.ConnectModeEnum.adModeUnknown,
                     ADODB.StreamOpenOptionsEnum.adOpenStreamUnspecified,
                     "", "");
            stm.Type = ADODB.StreamTypeEnum.adTypeBinary;

            stm.LoadFromFile(emlFilePath); 

            oMsg.DataSource.OpenObject(stm, "_stream"); 

            stm.Close();
            CDO.IBodyPart iPrt;
            int attachemtnCount = oMsg.Attachments.Count;

            for (int i = 1; i <= attachemtnCount; i++) {
                
                byte[] info_AttachmentBody;
                ADODB.Stream stm1;

            iPrt  = oMsg.Attachments[i] ;
                string attachmentFileName = iPrt.FileName; 
 
                Label1.Text  += attachmentFileName; //Get the eml attachment List
                if (iPrt.ContentTransferEncoding == "7bit ")
                {
                    //string_encoding   =   iPrt.GetDecodedContentStream.ReadText(iPrt.GetDecodedContentStream.Size) 
                    System.Text.ASCIIEncoding oEncoder = new System.Text.ASCIIEncoding();
                    info_AttachmentBody = oEncoder.GetBytes(iPrt.GetDecodedContentStream().ReadText(iPrt.GetDecodedContentStream().Size));

                }
                else   //如果是base64的话..这里不会了.
                {
                    stm1 = iPrt.GetDecodedContentStream();
                    stm1.Read(iPrt.GetDecodedContentStream().Size);
                    Label1.Text += stm1.ToString();
                }

            }

        }


    }
