namespace GPSlonandlat
{
    public static class GeoLocation
    {
        public static double geoloclon { get; set; }
        public static double geoloclat {get;set;}
  
        static GeoLocation()
        {
            GeoCoordinate coordinate = new GeoCoordinate();
            geoloclon = coordinate.Longitude;
            geoloclat = coordinate.Latitude;
        }
    }
}

geoloclon and geoloclat gets 'NaN'.. i am getting empty..

Note: i am running this project in local host. may be if i run in local host, i will be getting longitude and latitude to be empty.

You aren't finding your GeoCoordinate by doing that at all.
MSDN - system.device.location.geocoordinate[^]
If you look at the documentation on the GeoCoordinate class (link above) then you can see it states next to the default constructor "Initializes a new instance of GeoCoordinate that has no data fields set." This is why you are getting NaN values back.

This is a link to some MSDN example code for getting a devices location:
https://code.msdn.microsoft.com/windowsapps/Geolocation-2483de66[^]

okay. the one you put url that belongs to windows.

i am developing project using asp.net web app. how to get latitude and longitude of location

Although this is for MVC, I believe you could use a similar approach with standard ASP.Net but in essence you need some client side Javascript to post the geolocation data back to the server:

yes. i used JavaScript function which returns longitude and latitude. when i test in google map with those longitude and latitude, it shows wrong place.

if you look at android, just they use "LocationManager" class. they did not pass any address or pincode. But it returns longitude and latitude after they create object for location manager. likewise MSDN has System.Device.Location namespace. But i do not know to get longitude and latitude of my device located.
