How to check whether a page is run in production or dev or test in .NET/C#?

How can I check whether the page is run in a production, dev, or test environment in .NET/C#? In PHP I can use var_dump($_SERVER) to check, but somehow I have no idea how to check it in .NET or C#.

I need to find out whether the page is run in production/test/dev to display the correct logo and heading on the page.

Solution

You can setup as many configuration as you want, by default, you have Debug and Release.

You can make different web.config files for different configuration, for example: web.debug.config

From code you can use directives to test the configuration, for example:

#if DEBUG
  bool isDebug = true;
#else
  bool isDebug = false;
#endif
