StringBuilder sb = new StringBuilder();
  JsonWriter     writer = new JsonWriter(sb);

    writer.WriteArrayStart();
      writer.WriteObjectStart();
      writer.WritePropertyName("ObjName");
      writer.Write(key);
      writer.WritePropertyName("ClassName");
      writer.Write(str_className);
      writer.WriteObjectEnd();

    writer.WriteArrayEnd();

　　這是已經生成了 sb.tostring();

解析 生成的json

       string json = sb.tostring();
        JsonData data = new JsonData();
        data = JsonMapper.ToObject(json);

        foreach (JsonData item in data)
        {
            string objname = (string)item["ObjName"];

         //   GameObject obj = GameObject.Find(objname);

            string classname = (string)item["ClassName"];

            string[] _classname = classname.Split('|');

            List<string> list_className = new List<string>();
            for (int i = 0; i < _classname.Length; i++)
            {
                list_className.Add(_classname[i]);
            }

            dic.Add(objname, list_className);
        }    

將json 儲存到本地

 private  void Save(string jsong)
    {
        //string values = JsonMapper.ToJson(dic);
        string values = jsong;
        Debug.Log(values);
        //找到當前路徑
        FileInfo file = new FileInfo(filePath+ "/Dependence.bytes");
        //判斷有沒有檔案，有則開啟檔案，，沒有建立後開啟檔案
        StreamWriter sw = file.CreateText();
        //ToJson介面將你的列表類傳進去，，並自動轉換為string型別
      //  string json = JsonMapper.ToJson(personList.dictionary);
        //將轉換好的字串存進檔案，
        sw.WriteLine(values);
        //注意釋放資源
        sw.Close();
        sw.Dispose();
    }
