That there is no exception being thrown for ignored members is logical and expected behavior and no bug. Because the member is not missing, it is just ignored.
One relatively easy way to make an ignored member go "missing" is to create your own contract resolver derived from DefaultContractResolver, which removes ignored properties from the list of properties for an object contract. Something like this, for example:
I haven't tested this code myself (just written down from the top of my head, and therefore might contain typos or other errors), but it can serve as an illustration of the approach.
Note that the JsonProperty.Ignored value tested here is not only influenced by the JsonIgnoreAttribute, but also by other attributes.
Especially noteworthy is that JsonProperty.Ignored is also set by the JsonExtensionDataAttribute. If you are using this attribute, you will have to test thoroughly whether "blindly" removing the extension data property from the list of serializable properties (as my code example does) has any averse side effects.
public class Account
{
public string FullName { get; set; }
public bool Deleted { get; set; }
[JsonIgnore]
public bool DeletedDate{ get; set; }
}
string json = @"{
'FullName': 'Dan Deleted',
'Deleted': true,
'DeletedDate': '2013-01-20T00:00:00'
}";
try
{
JsonConvert.DeserializeObject(json, new JsonSerializerSettings
{
MissingMemberHandling = MissingMemberHandling.Error
});
}
catch (JsonSerializationException ex) //No Error returned
{
}
after setting MissingMemberHandling.Error does not seem to throw serialization exception for a property set with jsonignore
how to handle this?
