 1Load & Save ViewState Data#region Load & Save ViewState Data
 2        protected override object LoadPageStateFromPersistenceMedium()

 5            string viewState = Request.Form["__SmartViewState"];
 6            byte[] bytes = Convert.FromBase64String(viewState);
 7            //调用上面提供的静态方法CompressionHelper.DeCompressByte()来解压数据
 8            bytes = CompressionHelper.DeCompressByte(bytes);
 9            LosFormatter formatter = new LosFormatter();
10            return formatter.Deserialize(Convert.ToBase64String(bytes));

17            StringWriter writer = new StringWriter();
18            formatter.Serialize(writer, viewState);
19            string viewStateString = writer.ToString();
