Detecting Release/Debug mode in code

[CosmicCharlie]

I need a way to determine if my application is in debug mode or release mode in code. I need this so I can get a different connection string from a config file when I am in debug mode than when I am in release. Does anyone know how to do this or have any related recommendations?

Thank you.

'do something in Debug mode
#Else
'do something else in Release mode
#End If

Note that those are compiler directives. That means that when you compile your app in debug mode, the code in the <b>#ELSE</b> block will not be compiled.

Thank you, both. I knew it was easy, I just didn't know how.

To be on the safe side, I have implemented my code this way:

            m_strCnStrings = m_colCnStrings.Get("LiveConnString").ToString
#If DEBUG Then
            m_strCnStrings = m_colCnStrings.Get("TestConnString").ToString
#End If

That way, the Release code is compiled no matter what, and is overridden only in debug mode. This is, of course, slightly less efficient, but then only in debug mode, so my users won't care.

If you want to evaluate at runtime, you can use:

If System.Diagnostics.Debugger.IsAttached Then

    'Debug

Else

    'Release

End If

Thanks for the suggestion. It appears poorly documented by Microsoft. Can you tell me how this differs from using the compiler option?

#IF is a compiler directive, it will only compile when the build mode is set to Debug.

System.Diagnostics.Debugger.IsAttached is a run-time check to determine if there is a debugger attached. I would be careful using it in a check for the build version as a debug build can be executed with out a debugger attached.

Something else to consider.
I use File= to get appSettings that change between release types.
I use
<appSettings file="webTest.config">
or
<appSettings file="webProd.config">
in the web.config to point to the file that contains the appSettings that are different.

Yes, I have to change web.config depending on the release.
