I tried to place this code at the top of the MasterPage.master.cs page, but Viual Web Developer does not seem to like the syntax. This web is defined in C#. Can you provide some detailed instructions as this is all new to me? Where should the code be placed? Many thanks!

 No .. Do not use this code in the master page .. use it in the content page ..

 to change the culture of the page, you need to override the InitializeCulture.

there you can change the culture of the page ..

but first you need call the proper namespaces 

using system.threading;

using system.globalization

protected override void InitializeCulture() 
{ 
    
    System.Uri url = Request.Url; 
    string hostname = url.Host.ToString(); 
    
    string lang = null; 
    
    if (hostname == "urWebsite.com") { 
        lang = "en-US"; 
    } 
    else { 
        lang = "ar-JO"; 
    } 
    
    if ((lang != null)) { 
        if (!string.IsNullOrEmpty(lang)) { 
            Thread.CurrentThread.CurrentUICulture = new CultureInfo(lang); 
            Thread.CurrentThread.CurrentCulture = CultureInfo.CreateSpecificCulture(lang); 
        } 
        
    } 
} 

 
you add any language(culture) you want, just add it to the lang variable.

in my example, I am using the English Culture and Arabic Culture on some conditions the page will be changed to the proper Culture.

So I need to add this code to all the cs pages of the web sites? I tried it on the default.aspx.cs page as follows, but see some syntax errors on "void" and "cultureinfo" (sorry I need this with a teaspoon...):

using system.threading;

using system.globalization;

else {

if (!string.IsNullOrEmpty(lang)) {

 place the void InitializeCulture inside the page class.

using System.Threading;
using System.Globalization;

public partial class Default3 : System.Web.UI.Page
{
    protected override void InitializeCulture()
    {

        System.Uri url = Request.Url;
        string hostname = url.Host.ToString();
       string lang = null;
         if (hostname == "urWebsite.com")
        {
            lang = "en-US";
        }

        else
        {
            lang = "ar-JO";
        }


        if ((lang != null))
        {
             if (!string.IsNullOrEmpty(lang))
            {
                Thread.CurrentThread.CurrentUICulture = new CultureInfo(lang);

                Thread.CurrentThread.CurrentCulture = CultureInfo.CreateSpecificCulture(lang);

            }

        }

    } 
}

Looks like this os working great! Thanks very much for the replies. I want the culture to change on all the pages that the user navigates to, so I need to add the code to all the web pages. Is there a way to reference the same code in all the pages so that I won't have the same code in all the pages?

Yes you can .. Generate a base class that inherits from System.Web.UI.Page .. then write the repeated code inside that class.

Now lets all pages in the website inherits  from that base class ..
