Reflection: Distinguishing property from WithEvents field

Using reflection I need to find all (private and public) fields, defined with
the keyword WithEvents.

Those fields are reflected as properties, which makes me ask how to
distinguish between
Public Property X () As myClass and
Public WithEvents X As myClass

thank you very much. herbert

Well, don't you get an error compiling a class that has the above code? I
get: 'X' is already declared as 'Public Property X() as myClass'.

Aside from that, GetEvents works on the type. You can test which property
names are events.

I think it's not 100% reliably possible. 5 can be the result of 4+1 or 3+2.
I mean, the code VB produces by using Withevents could also be written
manually without using Withevents. You could look for a field named "_X" in
this case. If it's there, it _could_ be a WithEvents "variable" - or your
own code. Moreover, this is implementation detail and could change in a
newer version. I've looked for an attribute the VB compiler might attach,
but nope...
