移动短信回执

移动的短信回执，收到的编码是 “0031003065E500310031003A00320033002081F30031003500300033003100310039003900370030003477ED4FE190018FBE000A536B751F90E856DE5E94690D726959766CB95B89516895EE9898FF0C79F06B638FDB884C98CE96698BC44F30FF1B6B64524D670962A5905379F051765BCC542B53CD5F0F810280AA9178FF0C589E52A060A375C598CE9669”
和普通短信编码有很大区别，希望有人能解出来并提供方法，谢谢了。

这个是PDU串
  string _mobileNumber = “12345678901”;//手机号码
  string _content =”测试”;//短信同容
  string centerNo = “13800100500”;
  string length = string.Empty;
  string smstosendPDU = string.Empty;
  length = PDUencoding.CountSMSLength(_mobileNumber, _content);
  smstosendPDU = PDUencoding.PDUEncodingSMS(centerNo, _mobileNumber, _content);
  string str = "AT+CMGS=" + length + "\r" + smstosendPDU + "\x01A";//指令格式
  tbSmsPduCode.Text = str;
