is there way force wcf host fault? (more rest based wcf host.) there exception type can thrown cause host fault? if exception can't host faulted state, could?
in "api_root" function below, i've thrown several different types of exceptions, , either caught exception handler, or cause whole process fail(outofmemoryexception).
some example code. in vb, c# appreciated.
<servicecontract(name:="api", namespace:="urn:test")> public interface iwebserviceapi <operationcontract()> <webget(uritemplate:="getobject")> function api_root() object end interface <servicebehavior(instancecontextmode:=instancecontextmode.percall, includeexceptiondetailinfaults:=true)> public class webserviceapi implements iwebserviceapi public function api_root() object implements iwebserviceapi.api_root //throw exception type causes host fail return new object() end function end class function startservice() _service = new webservicehost(gettype(webserviceapi), baseaddresses) _service.open() addhandler _service.opened, addressof me.opened addhandler _service.closed, addressof me.closed addhandler _service.faulted, addressof me.faulted end function sub faulted(sender object, e eventargs) //handle falted service here end sub
the failed state not exist. but, if talking generic way close host can try:
system.servicemodel.operationcontext.current.host.close(); if failure mandatory you, state you're looking faulted. host object (whose type system.servicemodel.channels.communicationobject) has method named fault(), isn't public, you'll able call bit of reflection. should make host transitioning faulted state.
update. can use host derived webservicehost:
class mywebservicehost : system.servicemodel.web.webservicehost { public mywebservicehost(type servicetype, params uri[] baseaddresses) : base (servicetype, baseaddresses) { } public void fail() { base.fault(); } }
