How to find out the exact operation that is posted to Dispatcher

Is there a way where we can find out which UI element has posted an operation to the Dispatcher queue which eventually throws the event ,System.Windows.Threading.Dispatcher开发者_高级运维.CurrentDispatcher.Hooks.OperationPosted

Update : A private property DispatcherOperation.Name is showing what I need in the VS mouse-over in debugging mode. I just need to print this name to a logger for other debugging purposes. Is it possible to extract the Name dynamically.

Yes it is possible, while i give you a way to do it, i must warn you though, using reflection to get private or protected fields/properties/methods is never a good idea because first they are usually private for a reason and second of all if the signature or interface changes you code might break. But because you said it is just for debugging, this might be a valuable solution.

You can always use Reflection for these kind of things. First you need the Type and Instance of the object you want to read its private properties. Unfortunately i don't know if the Name you are looking for is a field or a property, but the overall procedure is similar. First get the property with GetProperty and then call GetValue on the returned PropertyInfo object. You might want to cache the PropertyInfo object to gain some speed while debug. You also need to use the correct BindingFlags again i don't know exactly how the field/property is described so i can't give you the exact code, but from here it should be easy to figure out.

Hope that helps.
