Question

For some reason I’m not getting this. (Example model below) If I write:

var property = typeof(sedan).GetProperty('TurningRadius'); Attribute.GetCustomAttributes(property,typeof(MyAttribute), false) 

the call will return MyAttribute(2) despite indicating I don’t want to search the inheritance chain. Does anyone know what code I can write so that calling

MagicAttributeSearcher(typeof(Sedan).GetProperty('TurningRadius')) 

returns nothing while calling

MagicAttributeSearcher(typeof(Vehicle).GetProperty('TurningRadius')) 

returns MyAttribute(1)?

---

Example Model:

public class Sedan : Car {     // ... }  public class Car : Vehicle {     [MyAttribute(2)]     public override int TurningRadius { get; set; } }  public abstract class Vehicle {     [MyAttribute(1)]     public virtual int TurningRadius { get; set; } }

Okay, given the extra information – I believe the problem is that GetProperty is going up the inheritance change.

If you change your call to GetProperty to:

PropertyInfo prop = type.GetProperty('TurningRadius',     BindingFlags.Instance | BindingFlags.Public | BindingFlags.DeclaredOnly); 

then prop will be null if the property isn’t overridden. For instance:

static bool MagicAttributeSearcher(Type type) {     PropertyInfo prop = type.GetProperty('TurningRadius', BindingFlags.Instance |                                           BindingFlags.Public | BindingFlags.DeclaredOnly);      if (prop == null)     {         return false;     }     var attr = Attribute.GetCustomAttribute(prop, typeof(MyAttribute), false);     return attr != null; } 

This returns true and only if:

• The specified type overrides the TurningRadius property (or declares a new one)
• The property has the MyAttribute attribute.
