如何使用Onvif库C＃获取设备信息？

Question

I am making ac# windows application which collects the devices connected to my network using an open source library Onvif.

i am doing in this way.

    ServicePointManager.Expect100Continue = false;
    var endPointAddress = new EndpointAddress("http://ip_address:port/onvif/device_service");
    var httpBinding = new HttpTransportBindingElement();            
    var bind = new CustomBinding(httpBinding);
    var temp = new DeviceClient(bind, endPointAddress);
    var request = new GetDeviceInformationRequest();
    var response = temp.GetDeviceInformation(request); ////// Error Here described bellow
    string firm = response.FirmwareVersion;
    string manu = response.Manufacturer;
    string serial = response.SerialNumber;
    string model = response.Model;

Error Message :: There was no endpoint listening at http:// something:port/onvif/device_service that could accept the message.this is often caused by an incorrect address or SOAP action

can any one help me?

I think i am not making proper connection with the server, is it so? if so then how to resolve it?

Answer 1

Maybe the WS-DISCOVERY gives you extra information. I would try not to use any port after the IP of the camera.

When the test sends an UDP to the multicast address 239.255.255.250, port 3702 (WS-Discovery), this is the camera's answer:

      </d:ProbeMatch>
    </d:ProbeMatches>

Try to discover the response and see if any XAddrs is not the default you expect.
