How Can I Use Preprocessor Directives (#if DEBUG) in My Razor Views?

Integrating Preprocessor Directives into Razor

Working with Razor can present challenges when it comes to incorporating preprocessor directives like #if debug. This article aims to elucidate the approach you can take to implement such directives within a Razor page.

Understanding the Extension Method

To effectively utilize preprocessor directives in Razor, consider defining an extension method. Here's an exemplary method that exposes a boolean flag indicating debug mode:

public static bool IsDebug(this HtmlHelper htmlHelper)
{
#if DEBUG
      return true;
#else
      return false;
#endif
}

Integrating into Razor Views

With the extension method at your disposal, you can seamlessly incorporate it into your Razor views. Observe the following code snippet:

<section>

Compiling with Specific Symbols

Since the helper is compiled with the appropriate DEBUG/RELEASE symbol, it accurately determines the current build configuration. This enables you to control the display of certain elements based on whether the project is in debug mode or not.

Practical Implementation

This approach allows you to leverage preprocessor directives in Razor pages, providing greater flexibility and control over your code's behavior based on debug mode.
