C# JSON按key进行排序

一次在调用百度外卖的接口中需要对JSON取MD5,但是前提是JSON必须先排序

  1.需要用到的库 JSON.NET

以下是源码

    /// 

    /// JSON对象名称排序  
    /// 
    public class JsonSort
    {
       /// 

       /// JSON格式化重新排序
       /// 
        /// 原始JSON JToken.Parse(string json);
       /// 初始值Null
       /// 
       public static string SortJson(JToken jobj, JToken obj)
        {
            if (obj == null)
            {
                obj = new JObject();
            }
            List list = jobj.ToList();
            if (jobj.Type == JTokenType.Object)//非数组
            {
                List listsort = new List();
                foreach (var item in list)
                {
                   string name= JProperty.Load(item.CreateReader()).Name;
                   listsort.Add(name);
                }
                listsort.Sort();
                List listTemp = new List();
                foreach (var item in listsort)
                {
                    listTemp.Add(list.Where(p=>JProperty.Load(p.CreateReader()).Name==item).FirstOrDefault());
                }
                list = listTemp;
                //list.Sort((p1, p2) => JProperty.Load(p1.CreateReader()).Name.GetAnsi() - JProperty.Load(p2.CreateReader()).Name.GetAnsi());
