C#对没有规律的json字符串转化为对象序列化并遍历读取

var jsonString={"BillDate":1,"TypeName":0,"StepNum":0,"CollectCode":0,"Uncollected":1,"Tax":0,"AbstractInfo":1}

现在我们要对这它进行转化并遍历读取：

/// <summary>
        /// 把json字符串转化为对象
        /// </summary>
        /// <param name="Json"></param>
        /// <returns></returns>
        public static JObject ToJObject(this string Json)
        {
            return Json == null ? JObject.Parse("{}") : JObject.Parse(Json.Replace(" ", ""));
        }

var objData=jsonString.ToJObject();
foreach(var m in objData)
{
     var aa = m.Key;
     var bb = m.Value;
}
