反序列化一维JSON数组C＃

Question

assuming below multiple single-dimensional JSON Array:

{
    "F" : [ "FG3D2", "FG492", "FG4Q2", "FG562", "FG5Y2", "FG6C2" ],
    "M" : [ "MG3D2", "MG492", "MG4Q2", "MG562", "MG5Y2", "MG6C2" ],
    "N" : [ "NG3D2", "NG492", "NG4Q2", "NG562", "NG5Y2", "NG6C2" ],
    "P" : [ "PG3D2", "PG492", "PG4Q2", "PG562", "PG5Y2", "PG6C2" ]
}

what is the appropriate class design that could be used to deserialize it ? deserialization with JSON.Net and JavascriptSerializer() works when deserializing as Dictionary<string, List<string>> but i can't seem to find the appropriate Class that is equivalent for this.

below is the class design i am trying to base the deserialization with but fails:

public class Element
{
    public string Key { get; set; }
    public List<string> Value { get; set; }
}

Thanks.

Answer 1

Really you need to change your json. As it stands you'll need a class something like

public class Element
{
    public List<string> F {get; set;}
    public List<string> M {get; set;}
    ....
}

To populate your existing class structure your json should be:

[
  {"Key":"F", "Value":["FG3D2", "FG492", "FG4Q2", "FG562", "FG5Y2", "FG6C2" ]},
  {"Key":"M", "Value":["MG3D2", "MG492", "MG4Q2", "MG562", "MG5Y2", "MG6C2"]},
]

this makes more sense to me than what you have at the moment

Answer 2

You have to change your JSON to make this work. You have to make a list of key/value pairs:

[
    {
        "Key": "F",
        "Value": [ "FG3D2", "FG492", "FG4Q2", "FG562", "FG5Y2", "FG6C2" ]
    },
    {
        "Key": "M",
        "Value": [ "MG3D2", "MG492", "MG4Q2", "MG562", "MG5Y2", "MG6C2" ]        
    },
    {
        "Key": "N",
        "Value": [ "NG3D2", "NG492", "NG4Q2", "NG562", "NG5Y2", "NG6C2" ]
    },
    {
        "Key": "P",
        "Value": [ "PG3D2", "PG492", "PG4Q2", "PG562", "PG5Y2", "PG6C2" ]
    }
]

Then you can convert it as follows:

var result = JsonConvert.DeserializeObject<List<RootObject>>(json);

Where RootObject is:

class RootObject
{
    public string Key { get; set; }
    public List<string> Value { get; set; }
}

Answer 3

how about this one:

    var dic = JsonDeserializer<Dictionary<string, List<string>>>(json);

    var els = new List<Element>();
    foreach(var k in dic.Keys)
    {
        els.Add(new Element { Key = k, Value = dic[k] });
    }

now you have your desired object.

Answer 4

I guess you can create a class inherited from the dictionary:

public class Element : Dictionary<string, List<string>>
{ }
