Starting application from data file

Question

When you double-click on a Word document, Word is automatically run and the document is loaded.

What steps are needed to do the same thing with my C# application?

In other words, assume my application uses ".XYZ" data files. I know how to tell Windows to start my application when a .XYZ data file is double clicked. But how do I find out within my application what data file was chosen so I can load it?

Answer 1

Granted this is a VB.NET solution, but this article has details on how to create the file association for your application in the registry and how to retrieve the command arguments when your application is fired up to do the proper file handling.

It looks easy enough to port over to C#.
