c＃Winforms-在类/ dll之间传递控件引用

Question

I have written a piece of software that supports plugin architecture. On the main GUI is a TextBox that I use to update the user with the status of the processes.

When I load a plugin, is it bad practice to pass a reference for that Textbox through to the plugin so that it can update it from within. Is this too highly coupled? Would it better practise with events?

Thanks.

Answer 1

I would suggest that you create an interface for communications between the plugin and its host. That would have an UpdateStatus method, and the implementation would update the textbox.

If you really only have one thing to do (updating the status) then you could use a simple delegate... but it seems likely that you may need more operations over time.
