Unexpected behavior when using objectType in JsonSerializer.Deserialize

[songqx]

I want to achieve deserialization, serialization and deserialization in ReadJson() by using JsonSerializer class.

Problem: CanConvert(() is called when the source code serializer.Deserialize(jsonReader,objectType );　is executed, and is in an infinite loop.

Expected behavior: How to convert the type of finalObject to type objectType,and don't cause any CanConvert() call loop. The sample code is below.Please help.

//sample code using System; using System.Collections.Generic; using System.IO; using System.Text; using System.Xml; using Newtonsoft.Json; using Newtonsoft.Json.Linq;

namespace Test { public class WPJsonConverter : JsonConverter { public override bool CanConvert(Type objectType) { return true; }

    //object→json
    public override void WriteJson(JsonWriter writer, object value, JsonSerializer serializer)
    {
        var jToken = JToken.FromObject(value, serializer);
        jToken.WriteTo(writer);
    }

    //json→object
    public override object ReadJson(JsonReader reader, Type objectType, object existingValue, JsonSerializer serializer)
    {
        //String serializedJson;
        JToken token = JToken.Load(reader);
        string jsonString = token.ToString();

        JsonTextReader jsonTextReader = new JsonTextReader(new StringReader(jsonString));

        var deserializeObject = serializer.Deserialize(jsonTextReader);

        var serializedToken = JToken.FromObject(deserializeObject);

        string serializedJson = serializedToken.ToString();

        var stringReader = new StringReader(serializedJson);

        var jsonReader = new JsonTextReader(stringReader);

        var finalObject = serializer.Deserialize(jsonReader,objectType );

        return finalObject;
    }

}
