How to Ignoring Fields and Properties Conditionally During Serialization Using JSON.Net?
I can't inherit from JsonIgnoreAttribute because it's a sealed class. What should I do?

我找到了答案.我從 JsonConverter 繼承并創建一個新的轉換器.
I found the answer. I inherit from JsonConverter and create a new convertor.
publicclassCustomJsonConverter : JsonConverter
{
publicoverridevoidWriteJson(JsonWriter writer, objectvalue, JsonSerializer serializer)
{
var list = (IList)value;
JArray s = new JArray();
foreach (var item in list)
{
JToken token = JToken.FromObject(item);
JObject obj = new JObject();
foreach (JProperty prop in token)
{
if (prop.Name != "Title") // your logic here
obj.Add(prop);
}
s.Add(obj);
}
s.WriteTo(writer);
}
publicoverrideobjectReadJson(JsonReader reader, Type objectType, object existingValue, JsonSerializer serializer)
{
thrownew NotImplementedException("Unnecessary because CanRead is false. The type will skip the converter.");
}
publicoverridebool CanRead
{
get { returnfalse; }
}
publicoverrideboolCanConvert(Type objectType)
{
return objectType != typeof(IList);
}
}
