Proper way to deserialize JSON to object in C# Unity 5? -


this question has answer here:

i developing simple unity game in c#. want send json data forth between unity , database. using unity's jsonutility deserialize, having trouble doing correctly.

here's json:

{     "table": {         "attributedefinitions":[         {             "attributename":"pleasework",             "attributetype":"s"         }     ],     "creationdatetime":1.501013735355e9,     "itemcount":0,     "keyschema":[         {             "attributename":"pleasework",             "keytype":"hash"         }     ],     "provisionedthroughput":{         "numberofdecreasestoday":0,         "readcapacityunits":5,         "writecapacityunits":5     },     "tablearn":"stringhere",     "tableid":"stringhere",     "tablename":"stringhere",     "tablesizebytes":0,     "tablestatus":"active"     } }

here's code create object:

rootobject res = rootobject.createfromjson(www.text); debug.log(res.table.tablename);

here classes:

[system.serializable] public class attributedefinition {     public string attributename { get; set; }     public string attributetype { get; set; } }  [system.serializable] public class keyschema {     public string attributename { get; set; }     public string keytype { get; set; } }  [system.serializable] public class provisionedthroughput {     public int numberofdecreasestoday { get; set; }     public int readcapacityunits { get; set; }     public int writecapacityunits { get; set; } }  [system.serializable] public class table {     public list<attributedefinition> attributedefinitions { get; set; }     public double creationdatetime { get; set; }     public int itemcount { get; set; }     public list<keyschema> keyschema { get; set; }     public provisionedthroughput provisionedthroughput { get; set; }     public string tablearn { get; set; }     public string tableid { get; set; }     public string tablename { get; set; }     public int tablesizebytes { get; set; }     public string tablestatus { get; set; } }  [system.serializable] public class rootobject {     public table table { get; set; }     public static rootobject createfromjson(string json)     {         return jsonutility.fromjson<rootobject>(json);     } }

the issue when call debug.log(res.table.tablename);, error below.

error:

nullreferenceexception: object reference not set instance of object

i'm sorry guys. noob @ stackoverflow , c# in general.

turns out question has been answered here, question being under different context.
