Blocking an Entire Country from accessing the website In ASP.NET

Suppose we have a  condition  that we don’t want to allow the access of our website  in certain parts of the world . That we can do here in ASP.Net .
In the process , it retrieves the country based on the browser . It  isn’t going to be 100% accurate but probably more like 80-90% .That’s because some people change the browser language instead of their native language and others use a non-ISO standard language. And last, some clients just don’t send language information.

This  process will be done in two main phases : 1. Resolve the culture

It resolves the CultureInfo based on the browsers language.

public static CultureInfo Culture()
       {
           string[] languages = HttpContext.Current.Request.UserLanguages;

           if (languages == null || languages.Length == 0)
               return null;

           try
           {
               string language = languages[0].ToLowerInvariant().Trim();
               return CultureInfo.CreateSpecificCulture(language);
           }
           catch (ArgumentException)
           {
               return null;
           }
       }

2. Resolve the country
This Method uses ResolveCulture() method above to create a RegionInfo object. The RegionInfo contains all the country information needed such as ISO code, EnglishName, NativeName and    DisplayName.

public static RegionInfo country()
        {
            CultureInfo culture = Culture();
            if (culture != null)
                return new RegionInfo(culture.LCID);

            return null;
        }

At Last Suppose we don’t want to give access  of the website to people of  “US”.
Then In page Load :

protected void Page_Load(object sender, EventArgs e)
        {
            Label1.Text = country().ToString();

            if (Label1.Text == "US")
            {
            Response.Redirect("PageYouWantToRedirect.aspx");
            }
        }
