Examples

MethodInfoDecoratorExtensions provides extension methods on Decorator.Enclose for detecting whether a reflected method overrides a base class implementation via IsOverridden. This example retrieves MethodInfo for PricingCalculator.Calculate (base method), RegionalPricingCalculator.Calculate (overridden), and RegionalPricingCalculator.FormatRegion (local method), then calls IsOverridden() on each. Console output shows False for the base method, True for the overridden method, and False for the local method that does not override anything.
