Reflections and private fields of event delegates in C #

Question

I’m probably doing something stupid, but here it is.

I am trying to get FieldInfo from a public event through reflection.

Check out this feature:

public void PlotAllFields(Type type) { BindingFlags all = BindingFlags.Instance | BindingFlags.NonPublic | BindingFlags.Public; FieldInfo[] fields = type.GetFields(all); Console.WriteLine(type + "-------------------------"); foreach (var fieldInfo in fields) { Console.WriteLine(fieldInfo.Name); } } public class Bar : Foo {} public class Foo { public string Test; public event EventHandler Event; public event RoutedEventHandler RoutedEvent; } 

Call PlotAllFields (typeof (Foo)); returns:

• Test
• Event
• RoutedEvent

Call PlotAllFields (typeof (Bar)); returns:

• Test

I understand that delegates behind events are private fields, so I cannot access them in a subclass. So far so good.

Then I tried: PlotAllFields (typeof (FrameworkElement)); // from WPF

• _themeStyleCache
• _styleCache
• _templatedParent
• _templateChild
• _flags
• _flags2
• _parent
• _inheritableProperties
• MeasureRequest
• Arrangerequest
• sizeChangedInfo
• _parentIndex
• _parent
• _proxy
• _contextStorage

Well ... Where are the 14 events of the FrameworkElement class ???

Answer 1

FrameworkElement does not use field events; it calls AddHandler and RemoveHandler . In most cases, they do not have handlers, so WPF uses a more economical system. For example, here is the Loaded event, from Reflector:

 public event RoutedEventHandler Loaded { add { base.AddHandler(LoadedEvent, value, false); } remove { base.RemoveHandler(LoadedEvent, value); } } 

Answer 2

try these anchor flags

 BindingFlags.Default | BindingFlags.FlattenHierarchy | BindingFlags.Instance | BindingFlags.NonPublic | BindingFlags.Public
