ErrorHandlingAttribute

This sample uses Argon.OnErrorAttribute to ignore the exception thrown setting the Roles property.

public class Employee :
    IJsonOnSerializeError
{
    public string Name { get; set; }
    public int Age { get; set; }

    public List<string> Roles
    {
        get
        {
            if (field == null)
            {
                throw new("Roles not loaded!");
            }

            return field;
        }
        set;
    }

    public string Title { get; set; }

    public void OnSerializeError(object originalObject, string path, object member, Exception exception, Action markAsHandled) =>
        markAsHandled();
}
