Hallo!
Gibt es eine Möglichkeit zur Laufzeit (mit Reflection) die Methoden festzustellen, die mit dem Click-Event eines Controls verbunden sind (.NET
Framework 1.1)?
Ich möchte nämlich versuchen, zur Laufzet die verbundenen Methoden durch eine ander Methode zu tauschen. Leider habe ich bis jetzt nicht herausfinden können wie ich zu den entsprechenden Informationen gelangen kann. Wenn ich den Code debuge kann ich mir die gesuchte Information ansehen (siehe Anhang: csharp_debug_menuitem_click.jpg, Markierung zeigt die mit dem Click-Event verbundene Methode, Breakpoint bei Methode btnStart_Click).
Ich bin über jede Hilfe dankbar.
