一个 ASP.NET Core 6.0 Web API 项目运行时日志中报错
System.ArgumentException: .NET number values such as positive and negative infinity cannot be written as valid JSON.
at System.Text.Json.ThrowHelper.ThrowArgumentException_ValueNotSupported()
at System.Text.Json.Utf8JsonWriter.WriteNumberValue(Single value)
请问如何解决？

通过添加 [JsonNumberHandling] attribute 解决了
public class ResultDocument
{
[JsonNumberHandling(JsonNumberHandling.AllowNamedFloatingPointLiterals)]
public float Score { get; set; }
}
