Extract attachment from HTTP POST (Stream) RRS feed

  • Question

  • Hi there,

    Web service needs to extract attachment (can be any type) from Stream.

    Stream comes from a Frevvo form. 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 is finding starting and end index positions of the attachment is greatly appreciated.
