json - How to deserialize into IREADONLY dictionary C# -

i'm trying deserialize json

{   "type": "correction",   "starttime": "2007-12-19t03:00:00.0000000-08:00",   "endtime": "2007-12-23t23:00:00.0000000-08:00",   "parameters": [     {       "key": "something",       "value": "1.8"     },     {       "key": "something2",       "value": "0.10000000000000001"     },     {       "key": "something3",       "value": "answer3"     },   ], } 

into dto including public ireadonlydictionary<string, string> parameters { get; set; } along many other things.

i'm using newest newtonsoft deserializer, function

var responseobject = jsonconvert.deserializeobject<tresponse>(jsonresponse); 

but returns error

newtonsoft.json.jsonserializationexception : cannot deserialize current json array (e.g. [1,2,3]) type 'system.collections.generic.ireadonlydictionary`2[system.string,system.string]' because type requires json object (e.g. {"name":"value"}) deserialize correctly. 

is there tool use change json response different response such

"parameters":      {       "something": "1.8",       "something2": "0.10000000000000001",       "something3": "answer3",     }, 

which works (since array removed).

p.s. i've used regex replace, since smallest json change cause fail, i've giving on approach.

thanks!

you can write custom jsonconverter

public class kvlisttodictconverter<t1,t2> : newtonsoft.json.jsonconverter {     public override bool canconvert(type objecttype)     {         return typeof(dictionary<t1, t2>) == objecttype;     }      public override object readjson(jsonreader reader, type objecttype, object existingvalue, jsonserializer serializer)     {             if (reader.tokentype == jsontoken.startarray)                 return serializer.deserialize<list<keyvaluepair<t1, t2>>>(reader).todictionary(x => x.key, x => x.value);             else             {                 var c = serializer.converters.first();                 serializer.converters.clear(); //to avoid infinite recursion                 var dict =  serializer.deserialize<dictionary<t1, t2>>(reader);                 serializer.converters.add(c);                 return dict;             }     }     public override void writejson(jsonwriter writer, object value, jsonserializer serializer)     {         throw new notimplementedexception();     } } 

and use in deserialization like

var json = jsonconvert.deserializeobject<yourobject>(json, new kvlisttodictconverter<string,string>()); 

this work both first json, , 1 want regex.
