Der Einfachheit halber ich nur drei Elemente reduct, und in der Tat gibt es mehr als 100. Ich möchte nur die Schlüsselnamen extrahieren, die „10000010.SH“ sind " 10000003.SH "," 10000006.SH "und so weiter. Ich deserialize es zu einem Objekttyp, aber wie man die Zeichenkette extrahiert, die ich will?

Object result= JsonConvert.DeserializeObject(jsonstring);

Oder gibt es eine bequeme Möglichkeit? Vielen Dank!

Answer 1

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

Answer 2

können Sie verwenden Linq mit Json.Net

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

Answer 3

Sie können es wie Deserialize dieser

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

Die Klassenstruktur wie

aussehen würde

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; } 
}
