I don't know whether this is the appropriate place to give product feedback,
but here goes:
I would love to see some kind of diagnostic to let me know when implicit
boxing has occurred.
We have had a few instances where one developer or another was working on
code, and did not realize that by passing their value type to a method that
accepted an object parameter (or in many cases, a delegate).
That's not an extremely common occurrence, but from time to time it can
happen, and in a team environment, it can be introduced by any developer,
and once it's done, it's not extremely noticeable. I would really love to
be able to do a build, or launch a probe, and be warned of lines where
implicit boxing is occurring. Then I or another team member could review
that code, to determine whether the boxing was intentional or accidental. 7 1958
Hi ,
I will do some research to find if there is a way to detect implicit boxing.
I will reply to you ASAP. Thanks for your understanding.

Thanks, Jeffrey. Is there a "suggestion box" for VS.Net out there
somewhere?

Hi ,
You can use the ILDASM tool to open the compiled assembly and check the IL
code to see if there is boxing involved. For example, the following C# code:
int i = 123;
object o = i;
will be compiled to the following IL code:
IL_0000: ldc.i4.s 123
IL_0002: stloc.0
IL_0003: ldloc.0
IL_0004: box [mscorlib]System.Int32
IL_0009: stloc.1
So it is boxed.
Actually, the following documentation lists the situations when boxing will
occur. http://msdn.microsoft.com/library/?u...tml/vclrfcshar
pspec_4_3_1.asp?frame=true
For suggestion to Microsoft, you can visit: http://register.microsoft.com/mswish...=EN-US&gssnb=1
or you can mail to ms****@microsoft.com
Your suggestion will make our product more efficient, thanks

Thank you for your help Jeffrey. In leiu of a warning from the tool,
perhaps we can make use of ILDASM by scanning the dissassembly of our
assemblies for instances of boxing.

Hi,
If you want to find out all of the places in your code where a boxing
operation occurs, you can dump the assembly to an output file using ildasm
and grep for the box instruction in your IL.
Happy Thanksgiving!
