c# - WCF Service . Setting response type to XML/JSON using the Accept HTTP Header? -

i want wcf service accept , respond requests in json or xml. thought wcf supposed automatically interpret response type based on accept header client specifies. in client request specify accept header application/json receive xml response.

this service definition:

[operationcontract] [webinvoke(method = "post", uritemplate = "/getchecks", bodystyle = webmessagebodystyle.bare)] check[] getchecks(mycustomobj object); 

im making request here :

using (webclient client = new webclient()) {     client.headers["content-type"] = "application/json";     client.headers["accept"] = "application/json";      string response = client.uploadstring(endpoint, jsonrequeststring);        // response xml } 

i know can make 2 endpoints , specify 1 xml , other json id rather not this.

any ideas?

for have on server set property automaticformatselectionenabled true

you can either in config

<webhttpendpoint>      <standardendpoint name="" helpenabled="true"                                   automaticformatselectionenabled="true"/>  </webhttpendpoint> 

or in code:

var host = new servicehost(typeof (pricingservice)); var beh = new webhttpbehavior { automaticformatselectionenabled = true }; host.addserviceendpoint(typeof (ipricingservice), new webhttpbinding(), uri)             .behaviors.add(beh);
