json.net获取获取json的属性名

        JArray jdata = JsonConvert.DeserializeObject<JArray>(ifo.Data);
        foreach (JObject jo in jdata)
        {
            Dictionary<string, string> values = JsonConvert.DeserializeObject<Dictionary<string, string>>(jo.ToString());
            foreach (string key in values.Keys)
            {//key是属性名,values[key]是属性的值}
}
