vb.net get event name

Question

Hi Experts,

I want to know a better way to get event name inside sub txt_TextCount_event.

Dim mb As Reflection.MethodBase = Reflection.MethodBase.GetCurrentMethod
Debug.Print("mb.name " & mb.Name)
it always give me mb.name : txt_TextCount_Validating, not txt_TextCount_Validated

Thank you very much !

Private Sub txt_TextCount_event(ByVal sender As Object, ByVal e As System.EventArgs) Handles txt_TextCount.Validating, txt_TextCount.Validated         
Dim errorMsg As String = String.Empty        
Dim mb As Reflection.MethodBase = Reflection.MethodBase.GetCurrentMethod        
Debug.Print("mb.name " & mb.Name)        
If mb.Name.Contains("Validating") Then
            do something        
ElseIf mb.Name.Contains("Validated") Then
            do the other some thing        
End If    
End Sub

Seems to me an impossible way, 

An event is handled by a method, in VB it is an addition in the Code made my Microsoft that you can tell which events are handled direct to the description of the method. 

However, that is not the case in C#, C++ or F# there you have always to do the equivalent of this VB code

AddHandler TheControl.TheEvent, Addressof TheMethodToBeHandled

Be also aware that an method can handle an endless quantity of events, maybe that explains it easier why you cannot get the event of a method.

In addition to Cor:

It doesn't make sense to check the name of the current method as it never changes at runtime. You specify it in code and it's always  "txt_TextCount_event". (BTW it's never "txt_TextCount_Validating"). EDIT: Names shouldn't matter at runtime anyway as they are made for the programmer only. At runtime, there are pointers and offsets.

The solution to be able to distinguish between events is not using the same event handler.

Hi experts,

I want to call same sub on events Validating and Validated.

As I building a large project, I want the coding as short as possible and easy to follow.

Any other suggest could be short and easy to follow?

Thank you very much

ElseIf mb.Name.Contains("Validated") Then
            do the other some thing        
End If    
End Sub

Again: The solution to be able to distinguish between events is not using the same event handler.

You want it simple but contradict yourself by writing code trying to distinguish between the events instead of simply using different handlers. Like we all do BTW.

It's like dripping two drops of water into the same bucket of water and finding them afterwards. Instead use different buckets.
