c# - ONVIF wsdl service: unable to authenticate -

i developing onvif driver using .net 4 (windows forms, not wcf). started importing wsdl files service in visual studio. able send command device in way:

httptransportbindingelement httptransportbindingelement = new httptransportbindingelement(); [...]  textmessageencodingbindingelement messegeelement = new textmessageencodingbindingelement(); [...] custombinding binding = new custombinding(messegeelement, httptransportbindingelement); [...]  endpointaddress serviceaddress = new endpointaddress(url);  deviceclient deviceclient = new deviceclient(binding, serviceaddress);  device channel = deviceclient.channelfactory.createchannel();  deviceservicecapabilities dsc = channel.getservicecapabilities(); 

but not able manage http digest authentication. spent days searching on google examples , solutions, ways seems hand write xml code. there not clean solution like:

deviceclient.channelfactory.credentials.httpdigest.clientcredential.username = username; deviceclient.channelfactory.credentials.httpdigest.clientcredential.password = digestpassword; 

(that doesn't work)?

first of should install microsoft.web.services3 package. (view> other windows> package manager console). must add digest behavior endpoint. first part of code passworddigestbehavior class , after used connecting onvif device service.

public class passworddigestbehavior : iendpointbehavior {     public string username { get; set; }     public string password { get; set; }      public passworddigestbehavior(string username, string password)     {         this.username = username;         this.password = password;     }       public void addbindingparameters(serviceendpoint endpoint, system.servicemodel.channels.bindingparametercollection bindingparameters)     {         // nothing     }      public void applyclientbehavior(serviceendpoint endpoint, system.servicemodel.dispatcher.clientruntime clientruntime)     {         //clientruntime.messageinspectors.add(new passworddigestmessageinspector(this.username, this.password));         clientruntime.messageinspectors.add(new passworddigestmessageinspector(this.username, this.password));     }      public void applydispatchbehavior(serviceendpoint endpoint, system.servicemodel.dispatcher.endpointdispatcher endpointdispatcher)     {         throw new notimplementedexception();     }      public void validate(serviceendpoint endpoint)     {         // nothing...     } }   public class passworddigestmessageinspector : iclientmessageinspector {     public string username { get; set; }     public string password { get; set; }      public passworddigestmessageinspector(string username, string password)     {         this.username = username;         this.password = password;     }      public void afterreceivereply(ref system.servicemodel.channels.message reply, object correlationstate)     {         // nothing     }      public object beforesendrequest(ref system.servicemodel.channels.message request, system.servicemodel.iclientchannel channel)     {         // use wse 3.0 security token class         var option = passwordoption.sendhashed;         if (string.isnullorempty(username) || string.isnullorempty(password))             option = passwordoption.sendplaintext;          usernametoken token = new usernametoken(this.username, this.password, option);          // serialize token xml         xmldocument xmldoc = new xmldocument();         xmlelement securitytoken = token.getxml(xmldoc);          // find nonce , add encodingtype attribute bsp compliance         xmlnamespacemanager nsmgr = new xmlnamespacemanager(xmldoc.nametable);         nsmgr.addnamespace("wsse", "http://docs.oasis-open.org/wss/2004/01/oasis-200401-wss-wssecurity-secext-1.0.xsd");         xmlnodelist nonces = securitytoken.selectnodes("//wsse:nonce", nsmgr);         xmlattribute encodingattr = xmldoc.createattribute("encodingtype");         encodingattr.value = "http://docs.oasis-open.org/wss/2004/01/oasis-200401-wss-soap-message-security-1.0#base64binary";         if (nonces.count > 0)         {             nonces[0].attributes.append(encodingattr);             //nonces[0].attributes[0].value = "foo";         }           //         messageheader securityheader = messageheader.createheader("security", "http://docs.oasis-open.org/wss/2004/01/oasis-200401-wss-wssecurity-secext-1.0.xsd", securitytoken, false);         request.headers.add(securityheader);          // complete         return convert.dbnull;     } } 

and how use it:

var endpointaddress = new endpointaddress("http://device_ipaddress/onvif/device_service");             var httptransportbinding = new httptransportbindingelement { authenticationscheme = authenticationschemes.digest };             var textmessageencodingbinding = new textmessageencodingbindingelement { messageversion = messageversion.createversion(envelopeversion.soap12, addressingversion.none) };             var custombinding = new custombinding(textmessageencodingbinding, httptransportbinding);             var passworddigestbehavior = new passworddigestbehavior(username, password);             var deviceservice = new deviceclient(custombinding, endpointaddress);             deviceservice.endpoint.behaviors.add(passworddigestbehavior);
