This seems related: #2839
from newtonsoft.json.
I've narrowed it down to line 2204 in JsonTextReader.cs
, where it inspects _floatParseHandling
. Wouldn't a fallback mechanism here work?
e.g. attempting conversion to decimal
, and if it overflows go to double
instead of throwing?
I realize it should probably have a new FloatParseHandling
enum value to avoid breaking existing implementations. Something like DecimalWithFallbackToDouble
(or something more concise)
Just an idea.

Typy źródłowe/docelowe
internal record Example(double Double, decimal Decimal);Źródłowy/docelowy kod JSON
{"Double":-1.7976931348623157E+308,"Decimal":-79228162514264337593543950335.0}Oczekiwane zachowanie
Oczekuję, że będzie można deserializować kod JSON z powrotem do przykładowego rekordu, nawet w przypadku korzystania z tego niestandardowego:
JsonConverter
class CustomConverter : JsonConverter { public override void WriteJson(JsonWriter writer, object? value, JsonSerializer serializer) { // Not relevant } public override object? ReadJson(JsonReader reader, Type objectType, object? existingValue, JsonSerializer serializer) { var token = JToken.ReadFrom(reader); var dbl = double.Parse(token["Double"]!.ToString()); var dec = decimal.Parse(token["Decimal"]!.ToString()); // Throws FormatException return new Example(dbl, dec); } public override bool CanConvert(Type objectType) => true; }
Rzeczywiste zachowanie
A jest zgłaszany podczas próby przeanalizowania ułamka dziesiętnego, ponieważ czytelnik domyślnie traktuje wszystkie liczby zmiennoprzecinkowe tak samo za pośrednictwem właściwości. Zmiana właściwości na po prostu przenosi problem do analizowania zamiast tego.
FormatException``FloatParseHandling``FloatParseHandling``Decimal``double
Steps to reproduce
var example = new Example(double.MinValue, decimal.MinValue); var json = JsonConvert.SerializeObject(example); var deserialized = JsonConvert.DeserializeObject<Example>(json, new CustomConverter());
