爲了簡單起見我約簡只有3元，而事實上有超過100我只是想提取密鑰的名稱，分別是「10000010.SH」，「 10000003.SH「，」10000006.SH「等。我反序列化它的對象類型，但如何提取我想要的字符串？反序列化netsted JSON字符串json.net

Object result= JsonConvert.DeserializeObject(jsonstring);

或有任何方便的方法？謝謝！

嘿@herbert看看我提供的解決方案，並確認是否可以幫助您。 :) –

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

這段代碼可以提取所有的密鑰嗎？鑰匙是不同的... – herbert

是的，但你需要糾正物體的類型 –

您可以使用LINQ與Json.Net

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

你可以反序列化這樣

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

類的結構看起來像

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; } 
}
