How to serialize a raw json field?

Question

I have a field in the db that store a json string and I want that when I return it in a json result that will be returned as json raw data and not warped with quotes as str

With Json.net you can define your own JsonConverters to apply a specific serialization behavior. You may apply it for a specific type or, if you have a view model, a specific property.

In your case you want to write the Images-string as a raw-string using JsonWriter.WriteRawValue.

Ie.

public class PlainJsonStringConverter : Newtonsoft.Json.JsonConverter
{
    public override bool CanConvert(Type objectType)
    {
        return objectType == typeof(string);
    }
    public override object ReadJson(JsonReader reader, Type objectType, object existingValue, JsonSerializer serializer)
    {
        return reader.Value;
    }
    public override void WriteJson(JsonWriter writer, object value, JsonSerializer serializer)
    {
        writer.WriteRawValue((string)value);
    }
}

public class MyViewModel
{
    public string id { get; set; }
    [Newtonsoft.Json.JsonConverter(typeof(PlainJsonStringConverter))]
    public string images { get; set; }
    /* ...  */
}
