JavaScriptSerializer.Deserialize（）转换成字典

我想以JSON解析Open Exchange Rates JSON，和我使用这种方法：JavaScriptSerializer.Deserialize（）转换成字典

HttpWebRequest webRequest = GetWebRequest("http://openexchangerates.org/latest.json"); 

HttpWebResponse response = (HttpWebResponse)webRequest.GetResponse(); 
string jsonResponse = string.Empty; 
using (StreamReader sr = new StreamReader(response.GetResponseStream())) 
{ 
    jsonResponse = sr.ReadToEnd(); 
} 

var serializer = new JavaScriptSerializer(); 
CurrencyRateResponse rateResponse = serializer.Deserialize<CurrencyRateResponse>(jsonResponse);

如果我理解正确JavaScriptSerializer.Deserialize我需要定义和对象把Json变成。

我可以用它的数据类型这样的成功连载：

public class CurrencyRateResponse 
{ 
    public string disclaimer { get; set; } 
    public string license { get; set; } 
    public string timestamp { get; set; } 
    public string basePrice { get; set; }   
    public CurrencyRates rates { get; set; } 
} 

public class CurrencyRates 
{ 
    public string AED { get; set; }  
    public string AFN { get; set; }  
    public string ALL { get; set; }  
    public string AMD { get; set; } 
}

我希望能够重播“CurrencyRates率”的东西，如：

public Dictionary<string, decimal> rateDictionary { get; set; }

但是解析器总是返回rateDictionary为null。任何想法，如果这是可能的，或者你有更好的解决方案吗？

编辑： 的Json看起来像这样：

{ 
    "disclaimer": "this is the disclaimer", 
    "license": "Data collected from various providers with public-facing APIs", 
    "timestamp": 1328880864, 
    "base": "USD", 
    "rates": { 
     "AED": 3.6731, 
     "AFN": 49.200001, 
     "ALL": 105.589996, 
     "AMD": 388.690002, 
     "ANG": 1.79 
    } 
}

你能告诉你的JSON的样子？ – 2012-02-10 13:47:04

@MichalB。 - 它在上面的链接，它已经添加了一个样本现在的帖子:) – iKode 2012-02-10 14:18:10

该代码可以使用您的样本数据

public class CurrencyRateResponse 
{ 
    public string disclaimer { get; set; } 
    public string license { get; set; } 
    public string timestamp { get; set; } 
    public string @base { get; set; } 
    public Dictionary<string,decimal> rates { get; set; } 
} 

JavaScriptSerializer ser = new JavaScriptSerializer(); 
var obj = ser.Deserialize<CurrencyRateResponse>(json); 
var rate = obj.rates["AMD"];

如果你的JSON是这样的：

{"key":1,"key2":2,...}

，那么你应该能够做到：

Dictionary<string, string> rateDict = serializer.Deserialize<Dictionary<string, string>>(json);

这编译：

string json = "{\"key\":1,\"key2\":2}"; 
var ser = new System.Web.Script.Serialization.JavaScriptSerializer(); 
var dict = ser.Deserialize<Dictionary<string, int>>(json);

你应该能够从这里弄明白你自己。

Below code will work fine, CurrencyRates is collection so that by using List we can take all reates. 
    This should work!! 

    public class CurrencyRateResponse 
    { 
     public string disclaimer { get; set; } 
     public string license { get; set; } 
     public string timestamp { get; set; } 
     public string basePrice { get; set; }   
     public List<CurrencyRates> rates { get; set; } 
    } 

    public class CurrencyRates 
    { 
     public string AED { get; set; }  
     public string AFN { get; set; }  
     public string ALL { get; set; }  
     public string AMD { get; set; } 
    } 

JavaScriptSerializer ser = new JavaScriptSerializer(); 
var obj = ser.Deserialize<CurrencyRateResponse>(json); 
var rate = obj.rates["AMD"];
