我的 api 代码：
var client = new RestSharp.RestClient("https://api.genelpara.com/embed/doviz.json");
var request = new RestRequest(Method.GET);
IRestResponse response = client.Execute(request);
var veri = JsonSerializer.Deserialize<DigerApiDoviz>(response.Content);
我的模型：
public class DigerApiDoviz
public Doviz doviz get; set;
public class Doviz
public decimal satis get; set;
public decimal alis get; set;
public decimal degisim get; set;
虽然接收到数据，但在“反序列化”操作中返回空值。因为我把我的模型弄错了。正确的建模过程是什么？
【问题讨论】：
看起来像字典var veri = JsonConvert.DeserializeObject<Dictionary<string, Doviz>>(response.Content); 不知道您正在使用的 JsonSerializer.Deserialize 重载。但显示的代码对我有用。
这不是NewtonSoft Json.Net Serializer吗？
@Ralf 当您将 döviz 类中的属性从十进制转换为字符串时，您提到的代码有效。谢谢
【参考方案1】：
我推荐用于反序列化的字典模型和 NewtonSoft.Json 作为序列化程序，因为您在序列化方面遇到了一些问题
Dictionary<string,Doviz> veri = JsonConvert.DeserializeObject<Dictionary<string,Doviz>> (response.Content);
你可以像字典一样使用它
Doviz dv =veri["USD"];
或者您可以将其转换为列表并使用 linq
List<DigerApiDoviz> list = veri
.Select(v => new DigerApiDoviz Name = v.Key, Doviz = v.Value ).ToList();
由于 json 只包含字符串属性，但 c# 对象应该具有小数属性，最好使用构造函数将字符串转换为小数，特别是因为 degisim 属性具有无效符号“，”
public class Doviz
[JsonProperty("satis")]
public decimal Satis get; set;
[JsonProperty("alis")]
public decimal Alis get; set;
[JsonProperty("degisim")]
public decimal Degisim get; set;
[JsonConstructor]
public Doviz (string satis, string alis, string degisim)
Satis=Convert.ToDecimal(satis);
Alis=Convert.ToDecimal(alis);
Degisim= Convert.ToDecimal(degisim.Replace(",","."));
public class DigerApiDoviz
public string Name get; set;
public Doviz Doviz get; set;
【讨论】：
如果这解决了您的问题，我鼓励您“接受”它。以上是关于使用 c# 反序列化操作的主要内容，如果未能解决你的问题，请参考以下文章
