我必須創建一個表示以下 JSON 物件的 Dto 物件：
{
"Europe":{
"France":"Paris",
"UK":"London",
"Germany":"Berlin"
}
}
其中“Europe”是 Continent 型別物件的值，“France”、“UK”和“London”是物件 Country 的值：
public class Country
{
public string Name { get; set; }
public string Capital { get; set; }
}
您將如何用物件類表示該 JSON 物件？

使用Dictionary<string, Dictionary<string, string>>@ Camilo-Terevinto 建議的代理
using System.Text.Json.Serialization;
using System.Text.Json;
public class Continent
{
public string Name { get; set; }
public List<Country> Countries { get; set; } = new List<Country>();
}
public class Country
{
public string Name { get; set; }
public string Capital { get; set; }
}
string json = @"
{
""Europe"":{
""France"":""Paris"",
""UK"":""London"",
""Germany"":""Berlin""
}
}
";
var dic = JsonSerializer.Deserialize<Dictionary<string,Dictionary<string,string>>>(json);
var continents = new List<Continent>();
foreach(var key in dic.Keys) {
var continent = new Continent() { Name = key };
foreach(var subkey in dic[key].Keys)
{
continent.Countries.Add(new Country() { Name = subkey, Capital = dic[key][subkey] });
}
continents.Add(continent);
}

嘗試這個
var json="{\"Europe\":{\"France\":\"Paris\",\"UK\":\"London\",\"Germany\":\"Berlin\"}}";
var result= JsonConvert.DeserializeObject<EuropeCountry>));
var continent = new Continent {
Name = nameof( result.Europe),
Countries = result.Europe.Select(e => new Country {Name=e.Key, Capital=e.Value} ).ToList()
};
public class Continent
{
public string Name { get; set; }
public List<Country> Countries { get; set; }
}
public class EuropeCountries
{
public Dictionary<string, string> Europe {get;set;}
}
