You can handle both formats (the JSON number representation and the masked string format) using a custom JsonConverter
class like this.
class DecimalConverter : JsonConverter
{
public override bool CanConvert(Type objectType)
{
return (objectType == typeof(decimal) || objectType == typeof(decimal?));
}
public override object ReadJson(JsonReader reader, Type objectType, object existingValue, JsonSerializer serializer)
{
JToken token = JToken.Load(reader);
if (token.Type == JTokenType.Float || token.Type == JTokenType.Integer)
{
return token.ToObject<decimal>();
}
if (token.Type == JTokenType.String)
{
// customize this to suit your needs
return Decimal.Parse(token.ToString(),
System.Globalization.CultureInfo.GetCultureInfo("es-ES"));
}
if (token.Type == JTokenType.Null && objectType == typeof(decimal?))
{
return null;
}
throw new JsonSerializationException("Unexpected token type: " +
token.Type.ToString());
}
public override void WriteJson(JsonWriter writer, object value, JsonSerializer serializer)
{
throw new NotImplementedException();
}
}
To plug this into your binder, just add an instance of the converter to the Converters
list in the JsonSerializerSettings
object:
JsonSerializerSettings settings = new JsonSerializerSettings
{
NullValueHandling = NullValueHandling.Ignore,
MissingMemberHandling = MissingMemberHandling.Ignore,
Formatting = Formatting.None,
DateFormatHandling = DateFormatHandling.IsoDateFormat,
Converters = new List<JsonConverter> { new DecimalConverter() }
};
