Update Progress bar from Class' BackgroundWorker

I am trying to update progress bar from the class that does the copying

In the my copy class I have

public event EventHandler Copy_OnProgressChange;

private void CopyWorker_ProgressChanged(object sender, System.ComponentModel.ProgressChangedEventArgs e)
        {
            EventHandler handler = Copy_OnProgressChange;
            if (handler != null) handler(this, e);
        }

And in the main class

CopyList[i].Copy_OnProgressChange += CopyProgressMessage;

    void CopyProgressMessage(object sender, EventArgs e)
    {
      //update progressBar with percentage
    }

As you can see I can not pass percentage from ProgressChangedEventArgs to eventhandler. Is there an easy way to fix this?

It doesn't look like your event handler isn't structured correctly... It requires the second argument to be: ProgressChangedEventArgs instead of EventArgs...

ProgressChangedEventArgs has a property named: ProgressPercentage.

You should change your event to be EventHandler<ProgressChangedEventArgs>, so that it will pass the derived type with the progress property.
