我如何反序列化这种类型的数据结构

Question

This is my JSON:

"Dt": {    
    "20171021": {    
      "abc": "-"    
    },    
    "20171022": {    
      "abc": "-"    
    },    
    "20171023": {    
      "abc": "-"    
    },    
    "20171024": {    
      "abc": "-"    
    },    
    "20171025": {    
      "abc": "-"    
    }
}

The properties inside Dt is all dynamic. They are all dates but in string format. So I am thinking if I would need a List object but how would JSON.Net map this into List? I am thinking of class structure something similar to:

public class Dt
{
    public List<RealDate> RealDates { get; set;}
}

public class RealDate
{
    public string Date{ get; set;} //to hold "20171021"

    public Tuple<string, string> Keys {get; set;} // to hold abc as Key1 and - as Key2
}

Any help is appreciated.

Answer 1

That look like there is no Dt , and the thing that currently has a Dt should actually have:

public Dictionary<string, Foo> Dt { get; set;}

where Foo is:

class Foo {
    public string abc {get;set}
}

You would then post-process this to turn the DTO model (the serialization model) into your actual model.

Remember: any time that there is even a minor difference between what the serialized data looks like, and what your domain model looks like: add a DTO model, and just map between them manually. It'll save your sanity.

Answer 2

Your json is invalid (brackets are missing), but the following json

{
    "Dt": {
        "20171021": {
            "abc": "-"
        },
        "20171022": {
            "abc": "-"
        },
        "20171023": {
            "abc": "-"
        },
        "20171024": {
            "abc": "-"
        },
        "20171025": {
            "abc": "-"
        }
    }
}

Can be deserialized into the following objects:

public class Model
{
    [JsonProperty("Dt")]
    public Dictionary<string, Value> Data { get; set; }
}

public class Value
{
    [JsonProperty("abc")]
    public string Abc { get; set; }
}

Testing the code:

string json = @"{
    ""Dt"": {    
    ""20171021"": {    
      ""abc"": ""-""    
    },    
    ""20171022"": {    
      ""abc"": ""-""    
    },    
    ""20171023"": {    
      ""abc"": ""-""    
    },    
    ""20171024"": {    
      ""abc"": ""-""    
    },    
    ""20171025"": {    
      ""abc"": ""-""    
    }
}
}";

var model = JsonConvert.DeserializeObject<Model>(json);
