I have an object with predefined data structure:
public class A
{
public string Id {get;set;}
public bool? Enabled {get;set;}
public int? Age {get;set;}
}
and JSON is supposed to be
{ "Id": "123", "Enabled": true, "Age": 23 }
I want to handle JSON error in positive way, and whenever server returns unexpected values for defined data-types I want it to be ignore and default value is set (null).
Right now when JSON is partially invalid I'm getting JSON reader exception:
{ "Id": "123", "Enabled": "NotABoolValue", "Age": 23 }
And I don't get any object at all. What I want is to get an object:
new A() { Id = "123", Enabled = null, Age = 23 }
and parsing warning if possible. Is it possible to accomplish with JSON.NET?
To be able to handle deserialization errors, use the following code:
var a = JsonConvert.DeserializeObject<A>("-- JSON STRING --", new JsonSerializerSettings
{
Error = HandleDeserializationError
});
where HandleDeserializationError
is the following method:
public void HandleDeserializationError(object sender, ErrorEventArgs errorArgs)
{
var currentError = errorArgs.ErrorContext.Error.Message;
errorArgs.ErrorContext.Handled = true;
}
The HandleDeserializationError
will be called as many times as there are errors in the json string. The properties that are causing the error will not be initialized.
