c# - wcf restful service method input parameter: string vs stream -

-

can explain me? difference between wcf methods string , stream input parameters?

void method1(stream input) , void method2(string input)

when 1 should use stream input parameter? benefits , disadvantages , limits each of these approaches?

thank much.

you'd use stream parameter if want receive bytes incoming http request body in operation. that's "raw" mode mentioned @ http://blogs.msdn.com/b/carlosfigueira/archive/2008/04/17/wcf-raw-programming-model-receiving-arbitrary-data.aspx, , can use receive arbitrary data.

you'd use string parameter if want receive well-formatted string in of supported formats. out of box, means either json (the string value surrounded ") or xml (depending on body style of operation, either xml element node called <string> text value passed operation, or element name of operation, child element named parameter, child text node value passed operation.
