c# - Adding and Retrieving data from request context -

i'm trying attach api key operationcontext outgoing message header follows:

    public static void addapikeytoheader(string apikey, icontextchannel channel, string address)     {         using (operationcontextscope scope = new operationcontextscope(channel))         {             messageheader header = messageheader.createheader("apikey", address, apikey);             operationcontext.current.outgoingmessageheaders.add(header);          }     } 

but have no idea how retrieve header on server side. i'm using service authorisation manager , current operating context , try retrieve header this:

    public string getapikey(operationcontext operationcontext)     {         var request = operationcontext.requestcontext.requestmessage;          var prop = (httprequestmessageproperty)request.properties[httprequestmessageproperty.name];          return prop.headers["apikey"];     } 

but there no apikey header attached there. also, on debugging when inspect operationcontext cant seem see apikey header anywhere. can see i'm going wrong?

you can add custom header way :

using (channelfactory<imyservicechannel> factory =         new channelfactory<imyservicechannel>(new nettcpbinding()))       {        using (imyservicechannel proxy = factory.createchannel(...))        {           using ( operationcontextscope scope = new operationcontextscope(proxy) )           {              guid apikey = guid.newguid();              messageheader<guid> mhg = new messageheader<guid>(apikey);              messageheader untyped = mhg.getuntypedheader("apikey", "ns");              operationcontext.current.outgoingmessageheaders.add(untyped);               proxy.dooperation(...);           }        }                         } 

and service side, can header :

guid apikey =  operationcontext.current.incomingmessageheaders.getheader<guid>("apikey", "ns");
