I know how to program in c# but I dont know how to program in assembly language

Surprise! There are not octal or hexadecimal or decimal numbers in programming, so there is nothing to "convert". If in you programming language they are written in different base, in machine they are all "binary". You do not "convert" them, you simply assign one to another, no matter how are they presented in the text of the code. (Have you ever heard the source code is compiled? Do you have any idea what it does?)

If you need to present a number on screen, you create its textual representation and it is called "formatting". If you read textual representation (from file, for example) and need to make a binary integer of some type; this is called "parsing" and can be successful or not.

Sorry, I don't see any sense in writing any sample code here. You need to understand basic things first. At the moment, you're not ready to write or even read any code.

C# targets the CLR, so the closest assembly language equivalent from a .NET perspective would be MSIL. And yes, you can convert C# to readable MSIL. There are several tools that do that including free ones.

If you really want to learn assembly language, then you need to pick up a good book and start on it. Although unless you've done some native programming in C or C++ it will be a significant change.

There is this: Static Compilation in Mono[^] - I would recommend learning a bit about assembly anyway, it's fun - and you'll end up with a far better understanding of programming in general :)

You'll probably have to disassemble the generated executable to see any assembly - or check other command line options for the mono tools
