Serialize a Dictionary<string,Type> and remove key/value from JSON string

c#, datacontractserializer, json

Solution

It's not fun, but try this:

[Test]
public void Json()
{
         var input = @"{
   ""Description"":""test"",
   ""RoomTypes"":[
      {
         ""Key"":""A"",
         ""Value"":{
            ""Name"":""Delux""
         }
      },
      {
         ""Key"":""B"",
         ""Value"":{
            ""Name"":""Non delux""
         }
      }
   ],
   ""Url"":""http:\/\/test.com""
}";

    var temp = JsonConvert.DeserializeObject<Temp>(input);
    var transform = new Transform
        {
            Description = temp.Description,
            Url = temp.Url,
            RoomTypes = new List<IDictionary<string, Temp.NameObj>>()
        };

    foreach (var group in temp.RoomTypes)
    {
        var dic = new Dictionary<string, Temp.NameObj> {{@group.Key, @group.Value}};
        transform.RoomTypes.Add(dic);
    }

    Console.WriteLine(JsonConvert.SerializeObject(transform));
}

public class Transform
{
    public string Description { get; set; }
    public IList<IDictionary<string, Temp.NameObj>> RoomTypes { get; set; }
    public string Url { get; set; }
}


public class Temp
{
    public string Description { get; set; }
    public IList<GroupObj> RoomTypes { get; set; }
    public string Url { get; set; }

    public class GroupObj
    {
        public string Key { get; set; }
        public NameObj Value { get; set; }
    }

    public class NameObj
    {
        public string Name { get; set; }
    }
}

The idea is to use Json.Net's dictionary serialization to achieve the structure you want.

Problem

I have following code snippet in which I am serializing an object into JSON. The code is working fine, but I want to remove `Key` and `Value` keywords from the JSON string. Current output: ``` { "Description":"test", "RoomTypes":[ { "Key":"A", "Value":{ "Name":"Delux" } }, { "Key":"B", "Value":{ "Name":"Non delux" } } ], "Url":"http:\/\/test.com" } ``` Desired output: ``` { "Description":"test", "RoomTypes":[ { "A":{ "Name":"Delux" } }, { "B":{ "Name":"Non delux" } } ], "Url":"http:\/\/test.com" } ``` My test code: ``` namespace ConsoleApplication1 { [DataContract] public class Room { [DataMember] public string Url { get; set; } [DataMember] public string Description { get; set; } [DataMember] public Dictionary<string, RoomTypes> RoomTypes { get; set; } } [DataContract] public class RoomTypes { [DataMember] public string Name { get; set; } } public class Test { static void Main(string[] args) { Room room = new Room { Url = "http://test.com", Description="test" }; RoomTypes roomType1 = new RoomTypes() { Name = "Delux" }; RoomTypes roomType2 = new RoomTypes() { Name = "Non delux" }; room.RoomTypes = new Dictionary<string, RoomTypes>(); room.RoomTypes["A"] = roomType1; room.RoomTypes["B"] = roomType2; DataContractJsonSerializer dataContractSer = new DataContractJsonSerializer(typeof(Room)); StringBuilder sb = new StringBuilder(); MemoryStream ms = new MemoryStream(); dataContractSer.WriteObject(ms, room); var result = Encoding.UTF8.GetString(ms.ToArray()); Console.WriteLine(result); } } } ``` Is there a way to do this?
