{ 

         "title":"Holiday",

         "attachment":"",
         "genFile":"",
         "is_Holiday":1
      },
      {  
         "title":"Holiday",
         "titlePopup":"Holiday",

         "is_Holiday":1
      }
  ]
}

需要得到响应为

{

 "ResponseStatus": "True",

 "ResponseCode": "0",

 "ResponseMessage": "Calendar Details Received!!",

 "data":
 {

 "Jan": [

 {

 "title": "Holiday",

 "titlePopup": "Holiday",

 "end": "2018-01-03T23:00:00",

 "allDay": 0,

 "attachment": "",

 "genFile": "",

 "is_Holiday": 1

 },

 {

 "title": "Holiday",

 "titlePopup": "Holiday",

 "color": "#e1e5ec",

 "msgId": 0,

 "start": "2018-01-04T00:00:00",

 "end": "2018-01-04T23:00:00",

 "allDay": 0,

 ],

这对你有用，

 class Program
        {       
                static void Main(string[] args)
                {            
                    JObject parsed = JObject.Parse(File.ReadAllText("test.json"));
                   var response = JsonConvert.DeserializeObject<Example>(parsed.ToString());
                    var dict =(JObject) parsed["Data"];                
                    Dictionary<string,List<MonthInfo>> dictValues = new Dictionary<string,List<MonthInfo>>();
                    foreach(var itme in dict)
                    {
                        dictValues.Add(itme.Key,JsonConvert.DeserializeObject<List<MonthInfo>>(itme.Value.ToString()));
                    }

                response.Data = dictValues;
                Console.WriteLine(JsonConvert.SerializeObject(response));
                Console.ReadLine();
                }         

        }


        public class MonthInfo
        {
            public string title { get; set; }
            public string titlePopup { get; set; }
            public string color { get; set; }
            public int msgId { get; set; }
            public DateTime start { get; set; }
            public DateTime end { get; set; }
            public int allDay { get; set; }
            public string attachment { get; set; }
            public string genFile { get; set; }
            public int is_Holiday { get; set; }
        }



        public class Example
        {
            public string ResponseStatus { get; set; }
            public string ResponseCode { get; set; }
            public string ResponseMessage { get; set; }
            public Dictionary<string, List<MonthInfo>> Data { get; set; }

        }

输出：

好吧，如果没有任何代码，就更难查明你做错了什么。但下面是会产生你想要的输出的类

public class Month
{
    public string title { get; set; }
    public string titlePopup { get; set; }
    public string color { get; set; }
    public int msgId { get; set; }
    public DateTime start { get; set; }
    public DateTime end { get; set; }
    public int allDay { get; set; }
    public string attachment { get; set; }
    public string genFile { get; set; }
    public int is_Holiday { get; set; }
}

public class Data
{
    public List<Month> Jan { get; set; }
    public List<Month> Feb { get; set; }
}

public class RootObject
{
    public string ResponseStatus { get; set; }
    public string ResponseCode { get; set; }
    public string ResponseMessage { get; set; }
    public Data data { get; set; }
}
