反序列化JSON數據到C＃

Question

我有這個JSON文件

[{"Ticker":"610-KW", 
"Ric_Code":null, 
"Business_Description":"Sultan Center Food Products Company KSCC is a Kuwait-based public shareholding company that holds investments in diverse portfolio of companies within Kuwait and the Middle East, with a specific focus on the retail industry. The Company’s activities include the construction of central markets and restaurants; import, export and marketing of consumer goods; manufacturing of food products; operation of retail supermarkets, restaurants and catering services; trade and installation of telecommunication equipment; trade in readymade garments, shoes, suits, accessories and gifts, and investment in real estate and other industries.

,"Arabic_Name":"شركة مركز سلطان للمواد الغذائية (ش.م.ك.مقفلة)","English_Name":"SULTAN CENTER FOOD PRODUCTS COMPANY - K.S.C. (CLOSED)", 
"ValidationQuarters": 
[{"Period_End_Date":"2012-09-30T00:00:00","Purification_Percentage":0.0,"Status":"Fail","Standard":"QRC","OutStandingShares":578828800,"Treasury_Shares":null,"WhiteList":null}]} 

和我創造了這個類來反序列化

public class ValidationQuarter 
    { 
     public string Period_End_Date { get; set; } 
     public double Purification_Percentage { get; set; } 
     public string Status { get; set; } 
     public string Standard { get; set; } 
     public int OutStandingShares { get; set; } 
     public int? Treasury_Shares { get; set; } 
     public object WhiteList { get; set; } 
    } 

    public class QueryResult 
    { 
     public string Ticker { get; set; } 
     public object Ric_Code { get; set; } 
     public string Business_Description { get; set; } 
     public string Arabic_Name { get; set; } 
     public string English_Name { get; set; } 
     public List<ValidationQuarter> ValidationQuarters { get; set; } 
    } 

當調用該代碼

string result = c.getResultsByTicker(reqStr); 

       QueryResult qr = Newtonsoft.Json.JsonConvert.DeserializeObject<QueryResult>(result); 

它會引發錯誤

無法將JSON數組反序列化爲類型'webservicetry.QueryResult'。 第1行，位置1.

Answer 1

您的JSON代表QueryResult對象的數組。您試圖將它們反序列化爲單個實例。你只需要改變：

List<QueryResult> qrs = JsonConvert.DeserializeObject<List<QueryResult>>(result);
