   public static DataTable CopyToDataTable<T>(this IEnumerable<T> array)
        {
            var ret = new DataTable();
            foreach (PropertyDescriptor dp in TypeDescriptor.GetProperties(typeof(T)))
                ret.Columns.Add(dp.Name);
            foreach (T item in array)
            {
                var Row = ret.NewRow();
                foreach (PropertyDescriptor dp in TypeDescriptor.GetProperties(typeof(T)))
                    Row[dp.Name] = dp.GetValue(item);
                ret.Rows.Add(Row);
            }
            return ret;
        }

以上
