I want to know how to implement data in c#. I know I could use StructureLayout, but the declared memory size is different from c. I want the output to be 00-00-80-00-00-00-00-00-00.

    Use an array of bytes and explicit bit-handling when needed? – Some programmer dude Dec 16 '21 at 09:59
  • @Someprogrammerdude I don't even know how to do it. I have little knowledge about the structure of c.I'm working on an example datasheet on the Internet for 'can protocol'. –  REPEATSIT Dec 16 '21 at 10:16
  • Please note that this code alone is not enough to tell us which order the fields are. C standard says that **C compiler can put bit-fields in any order they wish.** So you need probably will need to read that information from manual of the compiler that this code was written for. – user694733 Sep 05 '22 at 09:50
  • Also, comments do not make any sense: `ARG1` is supposed to be single bit field. It cannot fit hexadecimal value `0x800` into it. – user694733 Sep 05 '22 at 09:51
