Sending Shape to UserForm in c#. (To do "preview" of my tool)

Hello. I want to do "preview" in my tool on C#. I did it in VBA by exporting to JPG (Thank FaneDuru). Now I'm trying C#. How do I transfer an image from a document to a form? Export to bitmap again? Or is there an easier way? I do reference Corel.Interpop.VGcore in c#. My project work in corel as tool fine. But, I can't send a picture to form in c#. I not understand how do it
