将Json对象反序列化为C＃

Question

Trying to deserialize json but as it has dynamic key value , unable to get the the data in the testTimedict object

JSON:

{ 
  "results": {  
    "timesheets": {
      "123456": { 
        "id": 123456,
        "user_id": 36036,
        "jobcode_id": 374398,
        ..
      },
      "635241": {
        "id": 635241,
        "user_id": 36036,
        "jobcode_id": 0,
        ..
      },
      ..   
    }
  }
}

C#:

public class testroot
{
    private testresults _results;

    [DataMember(Name = "results")]
    public testresults Results {get; set;}
}

[DataContract()]
public class testresults
{
    private testTimedict _timesheet;

    [DataMember(Name = "timesheets")]
    public testTimedict timesheetList {get; set;}
}

[DataContract(Name = "timesheets")]
public class testTimedict
{
    private Dictionary<string, TimeSheets> _timesheet;

    [DataMember()]
    public Dictionary<string, TimeSheets> timesheetList {get; set;}
}

public class TimeSheets
{

    private int _id;
    private int _user_id;
    private int _jobcode_id;
    [DataMember(Name = "id")]
    public int ID {
        get { return _id; }
        set { _id = value; }
    }

    [DataMember(Name = "user_id")]
    public int user_id {
        get { return _user_id; }
        set { _user_id = value; }
    }

    [DataMember(Name = "jobcode_id")]
    public int jobcode_id {
        get { return _jobcode_id; }
        set { _jobcode_id = value; }
    }
}

I am deserializing the string into dictionary but the deserializer returns nothing for the inner most child object ie "123456"{}

Answer 1

I use your classes but please consider better naming for them

[DataContract]
public class testroot
{
    private testTimedict _results;

    [DataMember(Name = "results")]
    public testTimedict Results { get; set; }
}

[DataContract]
public class testTimedict
{
    private Dictionary<string, TimeSheets> _timesheet;

    [DataMember(Name = "timesheets")]
    public Dictionary<string, TimeSheets> timesheetList { get; set; }
}

[DataContract]
public class TimeSheets
{

    private int _id;
    private int _user_id;
    private int _jobcode_id;
    [DataMember(Name = "id")]
    public int ID
    {
        get { return _id; }
        set { _id = value; }
    }

    [DataMember(Name = "user_id")]
    public int user_id
    {
        get { return _user_id; }
        set { _user_id = value; }
    }

    [DataMember(Name = "jobcode_id")]
    public int jobcode_id
    {
        get { return _jobcode_id; }
        set { _jobcode_id = value; }
    }
}

and you can deserialize with Json.Net - JsonConvert.DeserializeObject<testroot>(test);

Your "dynamic keys" for the timesheets are the same as the id properties inside your timesheet objects, so why not get rid of the duplication and make timesheets an array? Like so:

{ 
    "results": {  
        "timesheets": [ { 
            "id": 123456,
            "user_id": 36036,
            "jobcode_id": 374398
        }, {
            "id": 635241,
            "user_id": 36036,
            "jobcode_id": 0
        }]  
    }
}

That cleans up your c# model considerably:

public Results results { get; set; }

public class Timesheet
{
    public int id { get; set; }
    public int user_id { get; set; }
    public int jobcode_id { get; set; }
}

public class Results
{
    public List<Timesheet> timesheets { get; set; }
}
