inline asm

[emyztik]

is it possible to use inline asm in C# like in C++?

C++ Example:

_asm
{
     push 0
     push title
     push message
     push 0
     call blah
}

possible?

[emyztik]

yes? no? maybe so?

It appears not, in so far as every reference to "inline assembly" I can find in the help relates to C++. I've also never heard anyone mention doing it previously. I'd guess that you'd have to write your assembly code in a C++ library and reference that from your C# app.

Not sure whether this will help but,

Also, i found something on a site that might be interesting:

C# has a magical "unsafe" keyword that lets me write assembly language inline in a method body

/** 
 * Manipulates the stack directly.  Note the use
 * of the unsafe keyword which allows us to use
 * the __asm keyword.
 */
private unsafe string[] listFiles(string path) {
 	__asm {
  		push path
  		push 1	// number of arguments
  		
  		push "mFile"
  		getv // get the mFile global object
  		
  		push "listFiles"
  		callm // call mFile.listFiles method
  	}
}

Hang your head in shame. That is not assembly.

And no, C# doesn't do inline ASM. Or at least not natively. You can get a few crappy tools that let you fake it out but its still not the real deal.

If you want to get a benefit from ASm in a C# app then you'd be better off writing a DLL in ASM and linking it directly into your C# program. This has more or less the same effect as inline ASM anyway, both ways are a compromise in the "Managed code" paradigm.

C# and ASM are not designed to be used together. C++ and ASM are (sort of).

Hey, at least you aren't using VB.net

wossname, that's exactly what I wanted to know, thanks. I'll stick with C++ I guess

Thanks guys.
