Programatically create a SharePoint site based on a site definition

Here is a peice of code that I know you will find useful one day. Basically, you supply it with an existing site definition, say "STS#1", and this will then create a site for you, based on the supplied site definition, at the URL you asked for.

Here goes -

public static bool CreateSite(
   string parentSiteURL, string siteURLRequested,
   string siteTitle, string siteTemplateName)
{
   bool returnCondition = false; // Assume failure.

   const Int32 LOCALE_ID_ENGLISH = 1033;

   using (SPSite siteCollection = new SPSite(parentSiteURL))
   {
       SPWeb parentWeb = siteCollection.OpenWeb();
       SPWebTemplateCollection Templates =
           siteCollection.GetWebTemplates(Convert.ToUInt32(LOCALE_ID_ENGLISH));
       SPWebTemplate siteTemplate = Templates[siteTemplateName];
       if (parentWeb.Webs[siteURLRequested].Exists)
       {
           parentWeb.Webs.Delete(siteURLRequested);
       }

       parentWeb.Webs.Add(
           siteURLRequested,
           siteTitle,
           "",
           Convert.ToUInt32(LOCALE_ID_ENGLISH),
           siteTemplate,
           false, false);
      
       // All is good?
       returnCondition = true;
   }

   return returnCondition;
}
