c# - How to know WCF service availability? -


i want know whether wcf service available or not before making service call. best way?

how using this:

bool isserviceup = true; try {    string address = "http://localhost/myservice.svc?wsdl";   metadataexchangeclient mexclient = new metadataexchangeclient(new uri(address), metadataexchangeclientmode.httpget);    metadataset metadata = mexclient.getmetadata(); // if service down exception }    catch (exception ex) {     isserviceup = false; }

my service using net tcp binding.

can use net tcp binding?

edit: jaredpar. suppose first call gets succeeded , while second call server down. before making service call check state of proxy in open state , hence make service call gets time out. haven't set open or close time out default takes 1 minute , call gets caught in fault event handler of service in dispose proxy. time ui hangs , shd do?

please guide.

this type of test not possible. there no way reliably detect if given wcf, or networking call, succeed before attempt it. there many variables outside control.

  • the physical network
  • the power source on machine wcf running
  • the actual wcf program
  • the stability of hard drive on computer code or wcf code running

any of these can terminated / changed @ point in time. hence it's impossible predict whether or not given call succeed.

the best way approach problem make call add code handle cases fail.
