Example provided is for a different Delegate (the EventHandler<TEventArgs> Delegate)

### Type of issue

Other (describe below)

### Description

It is a confusing example.
This page is about the "`EventHandler Delegate`", but the example provided is for the "`EventHandler Delegate`".

I tried to get the "EventHandler Delegate" to work in my code, but it didn't work. I did eventually discover my mistake, but having an appropriate example would have made it much quicker.
I have no issue if you adjust the example to provide a sample for both Delegates.
