Is this what you were looking at from microsoft?
http://research.microsoft.com/research/pubs/view.aspx?msr_tr_id=MSR-TR-2003-32

There is also an extensible commercial compiler XC#
http://www.resolvecorp.com/ which might suit your needs; in fact they have
an example of almost exactly what you are trying to do here

Thank you Greg. Although, I don't think I wan't to substitute microsoft
compiler for a third party compiler and I don't want to create my own
compiler. Is there a middle way where i can intercept the compilation process
so that I read the attributes and convert them into code in the message body
and compile that code and produce the final assembly. maybe:

- compile into assembly with the attributes
- load the assembly, read the attributes and produce the code in the method
body
- compile the final code and generate the final assemble that has the
assertions.

wiser than I.

eacsub,

Refactor! & other refactoring tools have a "Create Method Contract"
refactoring that adds the checks for you.

Refactor! does a return rather then throw an exception, haven't used it
enough to know if that is configurable or not. Using DXCore (the *free*
runtime that Refactor! is based on) would allow you to create your own
"add-in" for VS that injects the code you want...

|I would like to solve the problem of method parameter verfication in order
to

example:
|
| void method(object param)
| {
| if (param = null)
| {
| throw new ArgumentNullException("param");
| }
| }
|
| and do it throw attibutes that decorate the mothods. but the I don't want
| the preformance hit associated with reflection especially when it's
| associated with each method invocation.
|
| Is it possible to some how make the complire produce the code by reading
the
| attributes? Is it possible to extend the compiler some how? I remeber
reading
| something about extending the compiler in MSDN but i can't find it. is
this
