c# - Newtonsoft inline formatting for subelement while serializing -


is possible create attribute serialize subelements inline (formatting.none) newtonsoft json.net?

i have huge set of data , want keep readeable. subelements not important , can writen inline.

{     "name": "xxx",     "desc": "xxx",     "subelem": [         {"val1": 1, "val2": 2, ...}, //inline,         {"val1": 1, "val2": 2, ...},         ...     ]     "subelem2": {         "val1": 1,         "val2": 2,         ...     } }

i want force inline serialization sub objects of models. in case, "subelem" items written inline. thanks

adding converter jsonconverterattribute on class trickier because simplest implementation lead infinite recursion converter calls itself. it's necessary disable converter recursive calls in thread-safe manner, so:

public class noformattingconverter : jsonconverter {     [threadstatic]     static bool cannotwrite;      // disables converter in thread-safe manner.     bool cannotwrite { { return cannotwrite; } set { cannotwrite = value; } }      public override bool canwrite { { return !cannotwrite; } }      public override bool canread { { return false; } }      public override bool canconvert(type objecttype)     {         throw new notimplementedexception(); // should applied property rather included in jsonserializersettings.converters list.     }      public override object readjson(jsonreader reader, type objecttype, object existingvalue, jsonserializer serializer)     {         throw new notimplementedexception();     }      public override void writejson(jsonwriter writer, object value, jsonserializer serializer)     {         using (new pushvalue<bool>(true, () => cannotwrite, val => cannotwrite = val))         using (new pushvalue<formatting>(formatting.none, () => writer.formatting, val => writer.formatting = val))         {             serializer.serialize(writer, value);         }     } }  public struct pushvalue<t> : idisposable {     action<t> setvalue;     t oldvalue;      public pushvalue(t value, func<t> getvalue, action<t> setvalue)     {         if (getvalue == null || setvalue == null)             throw new argumentnullexception();         this.setvalue = setvalue;         this.oldvalue = getvalue();         setvalue(value);     }      #region idisposable members      // using disposable struct avoid overhead of allocating , freeing instance of finalizable class.     public void dispose()     {         if (setvalue != null)             setvalue(oldvalue);     }      #endregion }

and apply class (or property) so:

[jsonconverter(typeof(noformattingconverter))] public class nestedclass {     public string[] values { get; set; } }  public class testclass {     public string avalue { get; set; }      public nestedclass nestedclass { get; set; }      public string zvalue { get; set; }      public static void test()     {         var test = new testclass { avalue = "a value", nestedclass = new nestedclass { values = new[] { "one", "two", "three" } }, zvalue = "z value" };         debug.writeline(jsonconvert.serializeobject(test, formatting.indented));     } }

the output of test() method above is:

{   "avalue": "a value",   "nestedclass":{"values":["one","two","three"]},   "zvalue": "z value" }

i have method allows user access comment have made on site. have post method lets them update comment. my normal solution send entire comment model through, let them update it, update on database when post back. involve sending commentid through in hiddenfor , can manipulated. how can verify commentid sent in get method same i'm getting in post , not able alter comment wish? how can verify commentid sent in method same i'm getting in post? basically have validate following things in post - user logged-in user. authenticated users post comments. commentid in post , should valid commentid , should present in database. userid associated logged-in user should same userid associated comment . comment should contain userid column, can check @ time of update. to make sure update happens comment has been sent in get - hold commentid in session , in post action compare commentid value in session .
