How would it be possible to remove all event handlers of the 'Click' event of a 'Button'?

I was working on WinForms project where I had to remove the click-EventHandler from a ToolStripMenuItem and replace it with my own Handler. (I had to modify the action taken when a contextMenu Item was clicked)

for me the code from user2113340 did not work. I had to modify it like this to work with ToolStripMenuItem:

    private void RemoveClickEvent(ToolStripMenuItem control)
    {
        FieldInfo eventClick = typeof(Control).GetField("EventClick", BindingFlags.NonPublic | BindingFlags.Static);
        PropertyInfo eventsProp = typeof(Component).GetProperty("Events", BindingFlags.NonPublic | BindingFlags.Instance);
        EventHandlerList events = (EventHandlerList)eventsProp.GetValue(control, null);
        FieldInfo headInfo = events.GetType().GetField("head", BindingFlags.NonPublic | BindingFlags.Instance);
        object head = headInfo.GetValue(events);
        FieldInfo keyType = head.GetType().GetField("key", BindingFlags.NonPublic | BindingFlags.Instance);
        object key = keyType.GetValue(head);
        Delegate d1 = events[key];
        events.RemoveHandler(key, d1);
    }
