PropertyInfoExtensions

Examples

PropertyInfoExtensions provides extension methods for PropertyInfo to detect auto-implemented properties via IsAutoProperty. This example defines a Sample class with an auto-property (AutoProperty) and a manually implemented property (ManualProperty) that uses a backing field with a null-guard in its setter, then retrieves both PropertyInfo instances via reflection and calls IsAutoProperty on each. Console output displays True for the auto-property and False for the manual one, confirming the extension correctly distinguishes compiler-generated get/set accessors from custom implementations.

        var manualProperty = typeof(Sample).GetProperty(nameof(Sample.ManualProperty), BindingFlags.Instance | BindingFlags.Public);

        Console.WriteLine(autoProperty.IsAutoProperty());
        Console.WriteLine(manualProperty.IsAutoProperty());
    }

    private sealed class Sample
    {
        private string _manual;

        public string AutoProperty { get; set; }

        public string ManualProperty
        {
            get => _manual;
            set => _manual = value ?? throw new ArgumentNullException(nameof(value));
        }
    }
}
