使用json.net反序列化netsted json字符串

Question

jsonstring =

    }
}

For simplicity I reduct to only 3 elements, and in fact there are more than 100. I only want to extract the key names, which are "10000010.SH", "10000003.SH", "10000006.SH" and so on. I deserialize it to an object type, but how to extract the string I want?

Object result= JsonConvert.DeserializeObject(jsonstring);

Or is there any convenient way? Thanks!

Answer 1

  var deser = new JavaScriptSerializer()
        .Deserialize<Dictionary<string, Dictionary<string, string >>>(val);
    var justDaily = deser["jsonstring"];

Answer 2

You can use Linq with Json.Net

var keys = JObject.Parse(jsonstring)
            .Properties()
            .Select(x => x.Name)
            .ToList();

Answer 3

You can Deserialize it like this

Dictionary<dynamic, NumberSH> ser = JsonConvert.DeserializeObject<Dictionary<dynamic, NumberSH>>(jsonstr);
foreach(var k in ser)
{
    Console.WriteLine(k.Key);
}

The class structure would look like

public class NumberSH
{

    [JsonProperty("TOTALTM")]
    public int TOTALTM { get; set; }

    [JsonProperty("STARTDATE")]
    public string STARTDATE { get; set; }

    [JsonProperty("UNDERLYINGWINDCODE")]
    public string UNDERLYINGWINDCODE { get; set; }

    [JsonProperty("EXE_MODE")]
    public string EXE_MODE { get; set; }

    [JsonProperty("WIND_CODE")]
    public string WIND_CODE { get; set; }

    [JsonProperty("LASTTRADINGDATE")]
    public string LASTTRADINGDATE { get; set; }

    [JsonProperty("EXE_ENDDATE")]
    public string EXE_ENDDATE { get; set; }

    [JsonProperty("MAINT_MARGIN")]
    public object MAINT_MARGIN { get; set; }

    [JsonProperty("EXE_TYPE")]
    public string EXE_TYPE { get; set; }

    [JsonProperty("US_TYPE")]
    public string US_TYPE { get; set; }

    [JsonProperty("SETTLEMENTMETHOD")]
    public string SETTLEMENTMETHOD { get; set; }

    [JsonProperty("US_NAME")]
    public string US_NAME { get; set; }

    [JsonProperty("US_CODE")]
    public string US_CODE { get; set; }
}
