how to update property automatically in c# -

-

i have json object. want update lastupdate property whenever of other properties set (changed).

how can fix without calling lastupdate property calling function?

public class tickerdata {     public string symbol { get; set; }     public string exchange { get; set; }     public securitytype securitytype { get; set; }     public string  currency { get; set; } // convert enum later      public strategy  entrystrategy { get; set; }     public ohlcv ohlcv { get; set; }     public historicaldataeventargs[] historicaldata { get; set; }     public datetime date { get; set; }     public decimal open { get; set; }     public decimal high { get; set; }     public decimal low { get; set; }      public decimal close { get; set; }     public datetime lastupdate { get; set; } }

it sounds more accomplish change tracking. i'm not sure how pure you're trying keep object, implement inotifypropertychanged maybe new caller information attributes in .net 4.5 - monitor changes properties , update lastupdate appropriately. read more here.
