How Can I Detect Missing Fields During Json.NET Deserialization?

Detect missing fields in Json.NET deserialization using JsonConvert

In Json.NET, deserialization may ignore missing properties in the JSON data, returning default values ​​instead of throwing errors. To correct this problem, be sure to detect when deserialization fails to find a property.

The default MissingMemberHandling setting in Json.NET is Ignore, which means the serializer silently ignores unknown properties. To raise an exception, set MissingMemberHandling to Error.

<code>JsonSerializerSettings settings = new JsonSerializerSettings();
settings.MissingMemberHandling = MissingMemberHandling.Error;</code>

With this setting, deserialization will throw a JsonSerializationException as shown below:

<code>try
{
    var badObj = JsonConvert.DeserializeObject<myjsonobjview>(wrongData, settings);
}
catch (Exception ex)
{
    // 在此处处理异常
}</myjsonobjview></code>

This ensures that missing fields in deserialized objects are detected and marked, allowing exceptions to be handled correctly and data integrity maintained.
