Question

I am currently using geolocation to get the user’s country name. Here is my code:

navigator.geolocation.getCurrentPosition(function (pos) {
    var latlng = pos.coords.latitude + "," + pos.coords.longitude;
    var apiurl = 'http://maps.google.com/maps/geo?output=json&sensor=false&q=' + latlng;
    var yqlqry = encodeURIComponent('select * from json where url="' + apiurl + '"');
    var yqlurl = 'http://query.yahooapis.com/v1/public/yql?q=' + yqlqry + '&format=json&callback=?';
    $.getJSON(yqlurl, function (data) {
        var countryName = data.query.results.json.Placemark.AddressDetails.Country.CountryName;
        var newCountryName = countryName.toLowerCase();
        if (newCountryName == "united states")
            newCountryName = "us";
        else if (newCountryName == "england" || newCountryName == "ireland" || newCountryName == "scotland" || newCountryName == "wales" || newCountryName == "northern ireland")
            newCountryName = "uk";
        else if (newCountryName == "australia")
            newCountryName = "au";
        else if (newCountryName == "canada")
            newCountryName = "ca";
        else
            newCountryName = "world";
        $('a[title = "' + newCountryName + '"]').trigger('click');
    });
});

I would rather use something on the server side. Does anyone know if you can get the user’s country name in C#?

On the server side, the only thing you can reply upon is the IP address, which you can use to perform a location lookup. There are free databases out there of IP address-to-location mappings, or you can use HostIP.info.

Look at https://stackoverflow.com/questions/372591/how-to-get-city-country-and-country-code-for-a-particular-ip-address-in-asp-ne for more info.
