In all the examples I've seen of the #if compiler directive, they use "DEBUG". Can I use "RELEASE" in the same way to exclude code that I don't want to run when compiled in debug mode? The code I want to surround with this block sends out a bunch of emails, and I don't want to accidentally send those out when testing.
I've never seen that before...but I have seen:
#if (DEBUG == FALSE)
and
#if (!DEBUG)
That work for ya?
On my VS install (VS 2008) #if RELEASE
does not work. However you could just use #if !DEBUG
Example:
#if !DEBUG
SendTediousEmail()
#endif

Nope.
While in debug configuration there is a DEBUG
defined constant (automatically defined by Visual Studio) while there is no such constant defined for release mode. Check your project settings under build.
Selecting [Define DEBUG constant] under Project -> Build is like including #define DEBUG at the beginning of every file.
If you want to define a RELEASE constant for the release configuration go to:
You can create you own conditional compile-time symbols (any name you like). Go to the "project Build dialog", located in the project properties box, menu option: Project->[projectname] Properties...
You can also define them "at the top of the C# code file". Like:
#define RELEASE
// or
#undef RELEASE
you can use the symbol in a #if statement:
#if RELEASE
// code ...
#elif …
// code ...
#endif
// or
#if !RELEASE
// code ...
#endif
I know this is an old question, but it might be worth mentioning that you can create your own configurations outside of DEBUG and RELEASE, such as TEST or UAT.
If then on the Build tab of the project properties page you then set the "Conditional compilation symbols" to TEST (for instance) you can then use a construct such as
#if (DEBUG || TEST )
//Code that will not be executed in RELEASE or UAT
#endif
You can use this construct for specific reason such as different clients if you have the need, or even entire Web Methods for instance. We have also used this in the past where some commands have caused issues on specific hardware, so we have a configuration for an app when deployed to hardware X.

Whilst M4N's answer (#if (!DEBUG)
) makes most sense, another option could be to use the preprocessor to amend other flag's values; e.g.
bool isRelease = true;
#if DEBUG
isRelease = false;
#endif
Or better, rather than referring to whether we're in release or debug mode, use flags that define the expected behavior and set them based on the mode:
bool sendEmails = true;
#if DEBUG
sendEmails = false;
#endif
This is different to using preprocessor flags, in that the flags are still there in production, so you incur the overhead of if (sendEmails) {/* send mails */}
each time that code's called, rather than the code existing in release but not existing in debug, but this can be advantageous; e.g. in your tests you may want to call your SendEmails()
method but on a mock, whilst running in debug to get additional output.
Nope.

"Pop Catalin" got it right. Controlling the definition based on the type of build provides a great deal of flexibility. For example, you can have a "DEBUG", "DEMO", and "RELEASE" configuration all in the same solution. That prevents the need for duplicate programming with two different solutions.
So yes #if RELEASE
or #if (RELEASE)
works the same as #if DEBUG
when the RELEASE Conditional compilation symbol is defined.
The following is taken from "Pop Catalin" post: If you want to define a RELEASE constant for the release configuration go to: * Project Properties -> Build * Select Release Mode * in the Conditional compilation symbols textbox enter: RELEASE
RELEASE
is not defined, but you can use
#if (!DEBUG)
...
#endif

why not just
#if RELEASE
#undef DEBUG
#endif
RELEASE
is not defined, but you can use
#if (!DEBUG)
