c# - Programmatically access the <compilation /> section of a web.config?

Question

Is there any way to access the <compilation /> tag in a web.config file?

I want to check if the "debug" attribute is set to "true" in the file, but I can't seem to figure out how to do it. I've tried using the WebConfigurationManager, but that doesn't seem to allow me to get to the <compilation /> section.

Update:

I know I could easily just load the file like an XML Document and use XPath, but I was hoping there was already something in the framework that would do this for me. It seems like there would be something since there are already ways to get App Settings and Connection Strings.

I've also tried using the WebConfigurationManager.GetSection() method in a few ways:

WebConfigurationManager.GetSection("compilation")// Name of the tag in the file
WebConfigurationManager.GetSection("CompilationSection") // Name of the class that I'd expect would be returned by this method
WebConfigurationManager.GetSection("system.web") // Parent tag of the 'compilation' tag

All of the above methods return null. I'm assuming there is a way to get to this configuration section since there is a class that already exists ('CompilationSection'), I just can't figure out how to get it.

Use:

using System.Configuration;
using System.Web.Configuration;

...

  CompilationSection configSection =
          (CompilationSection) ConfigurationManager.GetSection( "system.web/compilation" );

You can then check the configSection.Debug property.

TIP: if you need to know how to get a value from a config file, check the machine.config file in your WindowsMicrosoft.netFramework<version>CONFIG folder. In there you can see how all the configuration section handlers are defined. Once you know the name of the config handler (in this case, CompilationSection), you can look it up in the .Net docs.
