问题 I made a program. I also made my own file type, which the program can create, open, and edit. In Explorer, I right clicked on this new file type and selected "Open With" and chose my program. Of course, it just opens the program without loading the file. How do I let my program know that it's being requested to open a file on startup?

问题 I need help in how to create a custom file extension in my C# app. I created a basic notes management app. Right now I'm saving my notes as .rtf (note1.rtf).
