JavaScriptSerializer serialization of JSON time format

Using JavaScriptSerializer to serialize the JSON time format, the resulting datetime value is displayed as a JSON string in the form of "/date (700000+0500)/", apparently to be converted

\/date (1404098342309)/, after analysis, this 1404098342309 value is the total number of milliseconds that is the difference between the January 1, 1970 (the minimum value of datetime) and the date actually represented by dates.

1. Direct substitution with strings

Model M = new Model {Id = 1, Dt = DateTime.Now};        JavaScriptSerializer js = new JavaScriptSerializer ();        String str = js. Serialize (m);        str = regex.replace (str, @ "\\/date\ ((\d+) \) \\/", match = =         {            datetime dt = new DateTime (1970, 1, 1);            DT = dt. Addmilliseconds (Long. Parse (match. GROUPS[1]. Value));            DT = dt. ToLocalTime ();           Return dt. ToString ("Yyyy-mm-dd HH:mm:ss");        });
