У меня есть класс C# для модели

Код: Выделить всё

public class Position
{
public Dictionary? assetData { get; set; }
}
public class AssetData
{
[JsonPropertyName("assetId")]
public string? AssetID { get; set; }

//[JsonPropertyName("cusip2Set")]
//public Cusip2Set? Cusip2Set { get; set; }

//[JsonPropertyName("cusip")]
//public string? Cusip { get; set; }

[JsonPropertyName("secDesc1")]
public string? SecurityDescription { get; set; }

[JsonPropertyName("sedol")]
public string? Sedol { get; set; }

[JsonPropertyName("secTicker")]
public string? secTicker { get; set; }

[JsonPropertyName("isin")]
public string? isin { get; set; }

[JsonPropertyName("secType")]
public string? secType { get; set; }
}

Я пытаюсь десериализовать его с помощью приведенного ниже кода

Код: Выделить всё

var obj = JsonSerializer.Deserialize(responseContent, SingletonJsonSerializerOptions.s_readOptions);

Я также попробовал способ, описанный ниже, но все равно выдал ту же ошибку.

Код: Выделить всё

var obj = JsonSerializer.Deserialize(responseContent, SingletonJsonSerializerOptions.s_readOptions);

Почему он не работает и не может десериализоваться, и почему он выдает очень общую ошибку? Ошибка следующая. Помогите мне десериализовать JSON в класс Position или словарь AssetData.

Значение JSON не удалось преобразовать в XXXXXX.XXXXX.APICore.Models.XXXXXXX.Positions.AssetData. Путь: $ | НомерЛинии: 0 | BytePositionInLine: 1.
Там выдается ошибка, есть какая-нибудь помощь или идея, мой друг?

Согласно советам из комментариев, я начал реализацию с использованием списка вместо словаря, но она реализуется с использованием универсальных шаблонов, как показано ниже.

Код: Выделить всё

public class Position
{
public List AssetData { get; set; }
}
How can I fit it to implement this below way, with Generics

JsonSerializer.Deserialize(responseContent, SingletonJsonSerializerOptions.s_readOptions);

Я могу десериализовать данные, используя приведенный ниже подход

Код: Выделить всё

JsonSerializer.Deserialize(responseContent, SingletonJsonSerializerOptions.s_readOptions);

Но мне нужно использовать Generic (для класса Position), пожалуйста, помогите
