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

1. Direct substitution with strings

List<t> Serialization:

1:list<person> List = new List<person> ()

2: {

3:new person () {name= "Zhang San", age=28},

4:new person () {name= "John Doe", age=25}

5:};

6:

7:string jsonstring = jsonhelper.jsonserializer<list<person>> (List);

Serialization results:

"[{/" age/": 28,/" name/":/" Zhang San/"},{/" age/": 25,/" name/":/" John Doe/"}]"

dictionaries cannot be directly used for json,dictionary dictionaries to be converted to JSON instead of the original dictionary format, but in the form of dictionary key as the value of the name "key", with dictionary value as the name " Value ". Such as:

1:dictionary<string, string> dic = new dictionary<string, string> ();

2:dic. ADD ("Name", "Zhang San");

3:dic. ADD ("Age", "28");

4:

5:string jsonstring = Jsonhelper.jsonserializer < Dictionary<string, string>> (DIC);

Serialization results:

1: "[{/" key/":/" name/",/" value/":/" Zhang San/"},{/" key/":/" age/",/" value/":/" 28/"}]"
