Json数组到结构（C＃） [英] Json Array to Struct (C#)

问题描述

我得到了这个Json数据：

 {
1：{currency_code：USD，currency_name：USDOLLAR，购买：18990，transfer：18990，sell：19050}，
2：{currency_code：EUR，currency_name：EURO，买：23596.94，转让：23667.94，卖出：23981.34}，
} 

我声明这样的结构：

  public   class 货币
 {
  public   string  currency_code { get ;  set ; } 
  public   string  currency_name { get ;  set ; } 
  public   string  buy { get ;  set ; } 
  public   string  transfer { get ;  set ; } 
  public   string  sell { get ;  set ; } 
} 

我尝试使用Newtonsoft.Json dll，但仍然无法将json数组转换为我的结构。



任何人都有线索或示例代码？

解决方案

您的json无法直接转换为货币数组，因为它是键值对的形式。



我发现有一个额外的逗号，在json中添加了最后一个产生问题的内容。





我尝试将提供的json转换为 Dictionary< string，Currency> ，我从json中删除了错误的逗号后获得了成功。



试试这个。

 string json ={+ 
\1 \\ \\ ：{\ currency_code\ ：\ USD\ \ currency_name\：\ USDOLLAR\，\ buy\：\ 18990\ \ transfer\：\ 18990\ ，\sell\：\19050 \}，+ 
\2 \：{\currency_code \：\EUR \ \ currency_name\：\ EURO\，\ buy\：\ 23596.94\，\ transfer\：\ 23667.94\，\\ \\sell \：\23981.34 \}+ 
}; 
 
 
字典<字符串，货币> list = 
 new JavaScriptSerializer（）。Deserialize< Dictionary< string，Currency>>（json）; 

谢谢Prakash Kalakoti :-D



最后'，'是我的错，有r USD，EUR，HKD，AUD，bla bla但我只是复制其中的两个，我忘了删除最后一个'，'; P

backstr = wr.GetGroup（ SIJ-kjsgEoG9CtE9Rm8ZiyiwuL3-58K1fZlmXIU5iyYVEFoDJ7d0Idn3-bOooAf1GDIzrJua7Am0yZDXW3bWOUuK_xa6eBELSNhmwLaxhoX3C34g9HvYCf9BTOk9bBukFaLNsoU2djsRfm0M5UHPmw）;

I got this Json data:

{
"1":{"currency_code":"USD","currency_name":"USDOLLAR","buy":"18990","transfer":"18990","sell":"19050"},
"2":{"currency_code":"EUR","currency_name":"EURO","buy":"23596.94","transfer":"23667.94","sell":"23981.34"},
}

I declare struct like this:

public class Currency
        {
            public string currency_code { get; set; }
            public string currency_name { get; set; }
            public string buy { get; set; }
            public string transfer { get; set; }
            public string sell { get; set; }
        }

I tried with Newtonsoft.Json dll but still cant convert that json array to my struct.

Anybody got a clue or an example code?

解决方案

Your json can't be directly converted to Currency array as it is in the form of key value pair.

I have found that there is one extra comma "," got added in the last for the json which is creating the problem.


I tried converting the provided json to Dictionary<string, Currency> and I got success after removing the incorrect comma from the json.

try this.

string json = "{" +
                      "\"1\":{\"currency_code\":\"USD\",\"currency_name\":\"USDOLLAR\",\"buy\":\"18990\",\"transfer\":\"18990\",\"sell\":\"19050\"}," +
                      "\"2\":{\"currency_code\":\"EUR\",\"currency_name\":\"EURO\",\"buy\":\"23596.94\",\"transfer\":\"23667.94\",\"sell\":\"23981.34\"}" +
                      "}";

       
 Dictionary<string, Currency> list =
          new JavaScriptSerializer().Deserialize<Dictionary<string, Currency>>(json);

thank you Prakash Kalakoti :-D

the last ',' is my fault, there r USD, EUR, HKD, AUD, bla bla but i just copy 2 of them and i forgot to remove the last ',' ;P

backstr = wr.GetGroup("Sij-kjsgEoG9CtE9Rm8ZiyiwuL3-58K1fZlmXIU5iyYVEFoDJ7d0Idn3-bOooAf1GDIzrJua7Am0yZDXW3bWOUuK_xa6eBELSNhmwLaxhoX3C34g9HvYCf9BTOk9bBukFaLNsoU2djsRfm0M5UHPmw");
