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

    /// <summary>
    /// JSON对象名称排序  
    /// </summary>
    public class JsonSort
    {
       /// <summary>
       /// JSON格式化重新排序
       /// </summary>
        /// <param name="jobj">原始JSON JToken.Parse(string json);</param>
       /// <param name="obj">初始值Null</param>
       /// <returns></returns>
       public static string SortJson(JToken jobj, JToken obj)
        {
            if (obj == null)
            {
                obj = new JObject();
            }
            List<JToken> list = jobj.ToList<JToken>();
            if (jobj.Type == JTokenType.Object)//非数组
            {
                List<string> listsort = new List<string>();
                foreach (var item in list)
                {
                   string name= JProperty.Load(item.CreateReader()).Name;
                   listsort.Add(name);
                }
                listsort.Sort();
                List<JToken> listTemp = new List<JToken>();
                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());

c# 对JSON字符串排序(KEY/VALUE)

public string StortJson(string json)
{
      var dic = JsonConvert.DeserializeObject<SortedDictionary<string, object>>(json);
      SortedDictionary<string, object> keyValues = new SortedDictionary<string, object>(dic);
      keyValues.OrderBy(m => m.Key);//升序 把Key换成Value 就是对Value进行排序
      //keyValues.OrderByDescending(m => m.Key);//降序
      return JsonConvert.SerializeObject(keyValues);
}
