well
ildasm is limited , atleast for now, to disassemble IL binary.
yes
you exe can have native code mixed with your IL code - ildasm usually doesnt
touch the native code.
its
question of how you look at it right ? various systems have dissemblers and they
are all not always coverting ix86 binary to human readable form. ILdams also
puts in the effort of turing a lot of other information in teh exe to a readable
form other than just the IL code.
about
the mixed binary here is an example that i had mailed someone
today:
do
glance thorugh this :
#include
<stdio.h>
#using <mscorlib.dll>
using namespace
System;
__gc class
managed
{
public:
static void
hello()
{
Console::WriteLine("hello");
}
};
class
unmanaged
{
public:
static void
hello()
{
_asm {
mov
ax,0
}
printf("hello");
}
};
void
main()
{
unmanaged::hello();
}
and after
compilation :
