Create CultureInfo

<%@ Page Language="VB" %>
<%@ Import Namespace="System.Globalization" %>
<script runat="server">
   sub Page_Load(Sender as Object, e as EventArgs)
      dim strLanguage as string = Request.UserLanguages(0).ToString
      
      lblMessage.Text = "Primary language: " & strLanguage & "<br>"
      
      dim objCulture as new CultureInfo(strLanguage)
      lblMessage.Text += "Full name: " & objCulture.EnglishName & "<br>"
      lblMessage.Text += "Native name: " & objCulture.NativeName & "<br>"
      lblMessage.Text += "Abbreviation: " & objCulture.ThreeLetterISOLanguageName & "<br>"
      lblMessage.Text += "Current Time: " & DateTime.Now.ToString("D", objCulture) & "<br>"
      lblMessage.Text += "Parent: " & objCulture.Parent.EnglishName & "<br>"
      
   end sub   
</script>
<html><body>
   <b>Your user information:</b> 
   <asp:Label id="lblMessage" runat="server"/>
</body></html>


Select CultureAuto

In the <%@ Page %> directive, both the Culture and UICulture attributes are set to the value auto:en-US. 
The culture name that appears after the colon enables you to specify a default culture when a language preference cannot be detected from the browser.

<%@ Page Language="C#" Culture="auto:en-US" UICulture="auto:en-US"%>

        lblDate.Text = DateTime.Now.ToString("D");
        lblPrice.Text = (512.33m).ToString("c");
    }
