Change Locale of SharePoint Site Programatically

While working with SharePoint sites, we can change the regional settings of the site by using user interface and that’s easy to be done

You can do it like

Click on Site Actions > Site Settings > Click on Regional Settings link under Site Administration

and this is the small code using which you as a developer can do

I have used hardcoding here to Initialize CultureInfo object but you can do customizations according to your need

I hope this helps some one J

namespace ChangeCulture

{

  class Program

  {

    static void Main(string[] args)

    {

      using (SPSite site = new SPSite("http://yoursite"))

      {

        try

        {

          using (SPWeb web = site.RootWeb)

          {

            ChangeCulture(web);

          }

         }

        catch (Exception ex)

        {

         Console.WriteLine(string.Format("{0}:{1}", "Error: ", ex.Message));

        }

       }

      }

    private static void ChangeCulture(SPWeb web)

    {

      if (web != null)

      {

        web.AllowUnsafeUpdates = true;

        //Initialize CultureInfo

        CultureInfo ci = new CultureInfo("en-US");

        if (ci != null)

        {

          string.Format("{0}{1}", "Processing ", web.Name);

          web.Locale = ci;

          web.Update();

        }

         web.AllowUnsafeUpdates = false;

       }

       if (web != null)

       {

         foreach (SPWeb _web in web.Webs)

         {

           ChangeCulture(_web);

         }

       }

     }

    }

}
