LosFormatter objLosformatter = new LosFormatter();

                object obj = objLosformatter.Deserialize("/wEPDwUKMTk4MjU2Nzc5OA9kFgICAw9kFgICAQ88KwANAQAPFgQeC18hRGF0YUJvdW5kZx4LXyFJdGVtQ291bnQCDWQWAmYPZBYEAgEPZBYGZg9kFgICAQ8QDxYCHwBnZGRkZAICDw8WAh4EVGV4dAUBMWRkAgMPDxYCHwIFAkFBZGQCAg9kFgZmD2QWAgIBDxAPFgIfAGdkZGRkAgIPDxYCHwIFATJkZAIDDw8WAh8CBQJBQWRkGAEFBmd2dGVzdA88KwAKAQgCB2SIrsaND3MxRKi3uGNB5R0TDin4UQ==");
