WithWeb-pattern of Jonas Nilsson

Jonas Nilsson shows an interesting approach for working with SPSite and SPWeb which must be disposed. Create a helper method WithWeb and send an Action parameter:

public void WithWeb(string uri, Action<SPWeb> action)
{
    using (SPSite site = new SPSite(uri))
    {
        using (SPWeb web = site.OpenWeb())
        {
            action(web);
        }
    }
}
```Here is my implementation of this pattern:

public static class DisposalService {     public static void WithWeb(string uri, Action action)     {         using (var site = new SPSite(uri))         {             using (var web = site.OpenWeb())             {                 web.UnsafeUpdate(action);             }         }     }     public  static void WithElevatedWeb(string uri, Action action)     {         SPSecurity.RunWithElevatedPrivileges(() => WithWeb(uri, action));     } }

Action update = (SPWeb w) =>                         {                             UserService.UpdateOwners(owners, w);                             UserService.UpdateMembers(members, w);                         }; DisposalService.WithWeb(SPContext.Current.Web.Url, update);
