C# if/then directives for debug vs release

C# if/then directives for debug vs release

In C#, you can use preprocessor directives to conditionally compile code based on whether the application is being built in Debug or Release mode. Here are some commonly used directives for this purpose:

1. #if DEBUG / #endif: This directive is used to include code that should only be compiled when the application is built in Debug mode. For example:

 #if DEBUG Console.WriteLine("Debug mode"); #endif

2. #if RELEASE / #endif: This directive is used to include code that should only be compiled when the application is built in Release mode. For example:

 #if RELEASE Console.WriteLine("Release mode"); #endif

3. #if !DEBUG / #endif: This directive is used to include code that should only be compiled when the application is not being built in Debug mode. For example:

 #if !DEBUG Console.WriteLine("Not in Debug mode"); #endif

4. #if !RELEASE / #endif: This directive is used to include code that should only be compiled when the application is not being built in Release mode. For example:

 #if !RELEASE Console.WriteLine("Not in Release mode"); #endif

You can also combine these directives with other conditions, such as checking for the presence of a particular symbol or defining a symbol in your project properties. For example:

 #if DEBUG && TRACE Console.WriteLine("Debug mode with tracing"); #endif 
 #if MY_SYMBOL Console.WriteLine("My symbol is defined"); #endif

To define a symbol, you can go to your project properties and add it in the "Build" tab under the "Conditional compilation symbols" section. For example, if you add "MY_SYMBOL" to this section, the #if MY_SYMBOL directive in your code will be included in the build.

Examples

  1. "C# conditional compilation debug vs release"

    • Description: Using preprocessor directives to conditionally include code based on the build configuration (Debug or Release).
    #if DEBUG // Debug-specific code #else // Release-specific code #endif

  2. "C# conditional compilation for logging in debug mode"

    • Description: Including logging statements only in Debug builds using preprocessor directives.
    #if DEBUG // Logging statements for debug mode Console.WriteLine("Debug Log: Something happened"); #endif

  3. "C# conditional compilation for release optimization"

    • Description: Optimizing code specifically for Release builds using preprocessor directives.
    #if !DEBUG // Release-optimized code // Example: Disable asserts or logging #endif

  4. "C# conditional compilation for feature toggles"

    • Description: Enabling or disabling features using preprocessor directives based on the build configuration.
    #if DEBUG // Feature enabled only in Debug mode FeatureToggle.EnableDebugFeature(); #endif

  5. "C# conditional compilation for test code exclusion"

    • Description: Excluding test-specific code from Release builds using preprocessor directives.
    #if DEBUG // Code for test scenarios TestUtility.RunDebugTests(); #endif

  6. "C# conditional compilation for profiling in release"

    • Description: Including profiling code only in Release builds using preprocessor directives.
    #if !DEBUG // Code for profiling in Release mode Profiler.Start(); #endif

  7. "C# conditional compilation for conditional breakpoints"

    • Description: Adding conditional breakpoints in the code for debugging purposes using preprocessor directives.
    #if DEBUG // Code with conditional breakpoint for debugging Debugger.Break(); #endif

  8. "C# conditional compilation for environment-specific settings"

    • Description: Adjusting environment-specific settings using preprocessor directives based on the build configuration.
    #if DEBUG string apiUrl = "https://debug.api.com"; #else string apiUrl = "https://release.api.com"; #endif

  9. "C# conditional compilation for build information"

    • Description: Including build information or versioning details based on the build configuration.
    #if DEBUG const string BuildType = "Debug"; #else const string BuildType = "Release"; #endif

  10. "C# conditional compilation for code contracts"

    • Description: Utilizing preprocessor directives for enabling or disabling code contracts based on the build configuration.
    #if DEBUG Contract.Requires(someCondition); #endif
