C # Assembly series 02, use NotePad to view the Il code of the executable assembly

Continue to the previous article "C # Assembly series 01, write C # And il code in notepad, compile the Assembly with the DOS command, and run the program". There are already several assemblies in the as folder of the F disk. In this article, use NotePad to view the Il code of the executable assembly.
