c# - WCF Rest XML EndPoint.(HTTPPOST). Deserialise an external object -

-

i have service contract supposed accept widget input parameter. widget spec given me third party using contract. made appropriate data contracts , can use unit test (which using wcf service reference) serialize widget , http post.

it bare bones xml serialization embedded in body of httppost. not formed xml document. e.g.

 stringwriter sw = new stringwriter();         xmltextwriter xtw = new xmltextwriter(sw);         xtw.writestartelement("widget");         xtw.writeelementstring("datetime", widget.datetime);         xtw.writestartelement("status");         foreach (myservref.status status in widget.status)         {             xtw.writestartelement("status");             xtw.writeelementstring("bay", status.bay.tostring());             xtw.writeelementstring("currentstate", status.currentstate.tostring());             xtw.writeelementstring("sector", status.sector.tostring());             xtw.writeelementstring("spaceid", status.spaceid.tostring());             xtw.writeelementstring("statusid", status.statusid.tostring());             xtw.writeelementstring("transitiondatetime", status.transitiondatetime);             xtw.writeendelement();         }         xtw.writeendelement();         xtw.writeelementstring("uniqueid", message.uniqueid.tostring());         xtw.writeendelement();         xtw.close();          string xml = sw.tostring();

when third party tries use contract there error 400. using formatted xml doc has namespace declarations in it. e.g. 

    <widget xmlns:xsi="http://www.w3.org/2001/xmlschema-instance" xmlns:xsd="http://www.w3.org/2001/xmlschema"     uniqueid="8cf4df0f-e765-4afc-b6fa-cd90b07b67b2"     datetime="2015-08-02t01:00:29.2213364z" xmlns="http://www.thesite.com/">       <status>         <spaceid>00010003</spaceid>         <statusid>1658038</statusid>            </status>     </widget>

the contract is:

 [operationcontract]//don't decorate xml rest contracts use   web.config            response mycontract(widget widget);

the data contract is;

[datacontract(namespace = "")] public class widget {       private string _uniqueidfield;      private string _datetimefield;        [datamember]      public status[] status     {         get;         set;      }      [datamember]     public string uniqueid     {         { return _uniqueidfield; }         set { _uniqueidfield = value; }     }      [datamember]     public string datetime     {         { return _datetimefield; }         set { _datetimefield = value; }     } }

i have tried many options including alternate contract takes string parameter , used datacontractserializer deserialize widget.

essentially haven't clue how , floundering around looking correct way. appreciate can me solve this. thanks

if can make .net winform app , reference service work? if works should able wireshark requests see difference between winform app , third party's request.

i have data grid rows represent theta (0, pi) , columns represent phi (0, 2*pi) , f(theta,phi) density of dark matter @ location. wanted calculate power spectrum , have decided use healpy. what can not understand how format data healpy use. if provide code (in python obvious reasons) or point me tutorial, great! have tried hand @ doing following code: #grid dimensions nrows*ncols (subject change) theta = np.linspace(0, np.pi, num=grid.shape[0])[:, none] phi = np.linspace(0, 2*np.pi, num=grid.shape[1]) nside = 512 print "pixel area: %.2f square degrees" % hp.nside2pixarea(nside, degrees=true) pix = hp.ang2pix(nside, theta, phi) healpix_map = np.zeros(hp.nside2npix(nside), dtype=np.double) healpix_map[pix] = grid but, when try execute code power spectrum. specifically, : cl = hp.anafast(healpix_map[pix], lmax=1024) i error: typeerror: bad number of pixels if point me tutorial or edit code great. more specifications: data in 2d np array , can change numrows/...
