Static methods for Biz layer (ASP.Net)

Dear All, Actually I have done all my Biz(business layer) and DAL CRUD Opprations using static methodes and I just send my error messages to my log table

a sample of biz layer

public static bool Delete(Guid LogGroupID)
    {
        using (DAL.ChroXEntities db = new ChroX.DAL.ChroXEntities())
        {
            var q = (from lg in db.LogGroupSet
                     where (lg.LogGroupID == LogGroupID)

                     select lg).FirstOrDefault();
      开发者_C百科      if (q != null)
            {

                try
                {
                    db.DeleteObject(q);

                    db.SaveChanges();
                    return true;
                }
                catch (Exception ex)
                {

                    GeneralClass.LogError(ex);
                }


            }
            return false;
        }
    }

so what should i do to propagate an user friendly error to my users? thanks for ever, Kiarash

User friendly all depends on the context so from your biz-layer you should simply re-throw your exception

catch (Exception ex)
{
   GeneralClass.LogError(ex);
   throw;
}

Then higher up in your hireachy where you're actually calling your Delete method from, you should again have a try-catch statement but here in your catch you should extract the message and write it out to the user, either as html, a ajax-popup or whatever. As i said, user friendly all depends on the context, which you haven't told us much about here.
