Extract attachment from Stream RRS feed

  • Question

  • Frevvo form posts posts the data(xml and attachment) to the WCF RESTFul web service method. Stream also consists of an xml document, which is simply extracted as shown below. 

    Now it is required to extract the attachment from the Stream.

    //Read or extract XML doc from the Stream
                StreamReader sreader = new StreamReader(inStream);
                string xml = sreader.ReadToEnd();
                int startPos = xml.IndexOf("<ns:form");
                int endPos = xml.IndexOf("</ns:form>");
                string data = xml.Substring(startPos, (endPos + 10) - (startPos));
                XmlDocument doc = new XmlDocument();

    Help or resources greatly appreciated.

  • Maybe the attachments can be read in the same manner, but using other elements instead of “<ns:form>”? Check if xml string contains other data. Also check if attachments maybe are included into doc document.

  • Thanks Viorel.

    It is feasible to read the attachment similar to the above manner. Like help in finding the element, xml doc doesn't contain any attachment data.

    Further help appreciated.

  • I am afraid that there is no such way to tell you which element contains attachment.

    Call me ghost for short, Thanks
    To get the better answer, it should be a better question.
