c# - How to return response as Content-Type: application/x-www-form-urlencoded; from WCF service? -

after spending insane amount of time make wcf service accept requests content-type: application/x-www-form-urlencoded; (using stream suggested here best way support "application/x-www-form-urlencoded" post data wcf?)

it works.

however response

content-type: application/xml; charset=utf-8 <string xmlns="http://schemas.microsoft.com/2003/10/serialization/">result</string> 

but want

content-type: application/x-www-form-urlencoded; charset=utf-8 result 

where can set / hacked?

currently method looks this:

[webinvoke(uritemplate = "generate_license", bodystyle = webmessagebodystyle.bare, method = "post")] [operationcontract] string generatelicense(stream period); 

ok, resolved it seems:

public stream generatelicense(stream period)         {             stream result = new memorystream();              streamwriter sw = new streamwriter(result);             sw.write("license");             sw.flush();             result.position = 0;             weboperationcontext.current.outgoingresponse.contenttype = "application/x-www-form-urlencoded; charset=utf-8";             return result;         }
