PropertyInfoDecoratorExtensions

Examples

PropertyInfoDecoratorExtensions provides extension methods on Decorator.Enclose for detecting auto-implemented properties and override behavior via IsAutoProperty and IsOverridden. This example retrieves PropertyInfo for Product.Code (auto-property), Product.Label (expression-bodied), and FeaturedProduct.Summary (overridden in a derived class), then calls IsAutoProperty on the first two and IsOverridden on the third. Console output shows True for the auto-property, False for the expression-bodied property, and True for the overridden property, confirming correct identification of property characteristics.

Methods

IsAutoProperty(IDecorator<PropertyInfo>)

Determines whether the underlying PropertyInfo of the decorator is considered an automatic property implementation.

public static bool IsAutoProperty(this IDecorator<PropertyInfo> decorator)

Parameters

decorator IDecorator<PropertyInfo>

The IDecorator<T> to extend.

Returns

bool

true if the underlying PropertyInfo of the decorator is considered an automatic property implementation; otherwise, false.

Exceptions

ArgumentNullException

decorator cannot be null.

IsOverridden(IDecorator<PropertyInfo>)

Determines whether the underlying PropertyInfo of the decorator has been overridden.

public static bool IsOverridden(this IDecorator<PropertyInfo> decorator)

Parameters

decorator IDecorator<PropertyInfo>

The IDecorator<T> to extend.

Returns

bool

true if the underlying PropertyInfo of the decorator has been overridden; otherwise, false.

Exceptions

ArgumentNullException

decorator cannot be null.
