Pass extra parameters to an event handler?

Question

Let\'s say I want to pass some extra data when assigning an event handler. Consider the following code:

private void s

You could create a custom object having additional properties based on Object:

class CustomObject : Object
{
    public string SomeData;
}

private void setup(string someData)
{
    CustomObject customObject = new CustomObject { SomeData = someData };
    CustomObject.assignHandler(evHandler);
}

public void evHandler(Object sender)
{
    string someData = ((CustomObject)sender).SomeData;
}

If the data should not be changed anymore after initialization, you could also add a custom constructor, for example.
