    public static class RepositoryCreater
    {
        public static T CreateRepository<T>(string name)
        {
            string defintion = "DAL.Provider.ArticleProvider,DAL";            Type type = Type.GetType(defintion);            object obj = Activator.CreateInstance(type);            if (obj is T)
            {
                return (T)obj;
            }
            else
            {
                return default(T);
