Convert Key to Keys in C#

Question

I want to use the new Key Enumeration in my ObjectModel to avoid having a reference to Windows.Forms in this Dll. The GUI uses a class library that wants the Keys enumeration.

Is it possible in any way to convert a Key value to a Keys value?

EDIT: I just found out that my question was already asked and answered here: How can I convert 'System.Windows.Input.Key' to 'System.Windows.Forms.Keys'?

Are you asking how to convert between two different enumerations? One approach is to do it through casting to an int and then back to the other enum. — Bernard Chen, Jun 17 '11 at 06:25
@Bernard Chen no that doesn't work. A Key doesn't have the same numerical value as a Keys — Anemoia, Jun 17 '11 at 06:35
Thanks for the clarification. It's not something I'm familiar with. — Bernard Chen, Jun 17 '11 at 07:10

You can use KeyInterop.VirtualKeyFromKey Method to convert to a Win32 key, and then directly cast to winforms Keys.

I would say if you want to use a type declared in another assembly, in your case the enum, you should copy the whole definition in your own assembly, basically declaring it again.

what is worse then? having a cloned declaration or referencing windows.forms.dll ?
