尝试如下操作:

public void WriteTrace(object sender, EventArgs e, string eventName)
{
    Control c = (Control)sender;
    Console.WriteLine("Control: " + f.Name + ", Event: " + eventName);
}

public void SubscribeEvent(Control control, string eventName) {
    EventInfo eInfo = control.GetType().GetEvent(eventName);

    if (eInfo != null) {
        // create a dummy, using a closure to capture the eventName parameter
        // this is to make use of the C# closure mechanism
        EventHandler dummyDelegate = (s, e) => WriteTrace(s, e, eventName);

        // Delegate.Method returns the MethodInfo for the delegated method
        Delegate realDelegate = Delegate.CreateDelegate(eInfo.EventHandlerType, dummyDelegate.Target, dummyDelegate.Method);

        eInfo.AddEventHandler(control, realDelegate);
    }
}
