What is the safe way to call Debug.Assert from C++ CLI?

This blog does not recommend it: http://blog.kalmbachnet.de/?postid=78

But I want to do it anyway. I suppose I need to wrap my Debug.Assert with some sort of #if or #ifdef or something like that. Also, does anyone have a good example of a Debug.Assert in C++ CLI?

Suppose I have the following variable: String^ validationError = bldError.ToString(); And now I wish to do something like:

#if (DEBUG)
Debug.Assert(false, "Got the following validation error:" + validationError);
#endif

How can I do it safely in C++ CLI, and are there additional gotchas to check for?

EDIT: Based on the answers, I have come up with the following macro:

#ifdef _DEBUG
#define CLIASSERT(condition, ...) System::Diagnostics::Debug:开发者_StackOverflow:Assert(condition, ##__VA_ARGS__)
#else
#define CLIASSERT(condition, ...) // This macro will completely evaporate in Release.
#endif

And here is an example of usage:

String^ strValidationError = bldError.ToString();
CLIASSERT(false, L"Schema validation error: " + strValidationError);

The blog post is accurate. Make it look like this:

#ifdef _DEBUG
    Debug::Assert(...);
#endif

---

Pick one

#ifndef NDEBUG // or
#if !defined(NDEBUG) // or

#ifdef _DEBUG // or
#if defined(_DEBUG)

AFAIK NDEBUG is defined in the ISO C++ standard (also used to enable/disable the standard library's assert macro), whereas _DEBUG is Microsoft-specific.

(Of course C++/CLI is not ISO C++, but in this case it doesn't make a difference)

MS has documented this behaviour at http://msdn.microsoft.com/en-us/library/system.diagnostics.conditionalattribute.aspx -- put briefly, when you do a release build, a compiler may or may not disable Assert and other such methods marked with ConditionalAttribute. For example the C# compiler does disable them, C++/CLI compiler does not. Even though the blog post is fairly old, I'd find it unlikely that the situation would change, considering what it says at that MSDN page.
