c# - JSON.NET: Serialize json string property into json object -

is possible tell json.net have string json data? e.g. have class this:

public class foo {     public int id;     public string rawdata; } 

which use this:

var foo = new foo(); foo.id = 5; foo.rawdata = @"{""bar"":42}"; 

which want serialized this:

{"id":5,"rawdata":{"bar":42}} 

basically have piece of unstructured variable-length data stored json already, need serialized object contain data part.

thanks.

edit: make sure understood properly, one-way serialization, i.e. don't need deserialize same object; other system shall process output. need content of rawdata part of json, not mere string.

you need converter that, here example:

public class rawjsonconverter : jsonconverter {    public override void writejson(jsonwriter writer, object value, jsonserializer serializer)    {        writer.writerawvalue(value.tostring());    }     public override object readjson(jsonreader reader, type objecttype, object existingvalue, jsonserializer serializer)    {        throw new notimplementedexception();    }     public override bool canconvert(type objecttype)    {        return typeof(string).isassignablefrom(objecttype);    }     public override bool canread    {        { return false; }    }    } 

then decorate class it:

public class foo {     public int id;     [jsonconverter(typeof(rawjsonconverter))]     public string rawdata; } 

then, when use:

var json = jsonconvert.serializeobject(foo,                                     new jsonserializersettings()); console.writeline (json); 

this output:

{"id":5,"rawdata":{"bar":42}} 

hope helps

edit: have updated answer more efficient solution, previous 1 forced serialize deserialize, doesn't.
