You can check out the generated class if you run your Web application in debug mode ( in web.config) by looking in your Temporary ASP.NET Files folder in the .NET Framework directory. On my machine, the path looks something like this.
C:\Windows\Microsoft.NET\Framework\v2.0.50727\Temporary ASP.NET Files\compilationanddeployment\
fc448eb9\60feb83a
The directory names below the virtual name will vary for your machine and there may be multiple directories-you have to find the right one by looking at timestamps or simply by looking at file content. In this directory you will find the compiled DLLs for the APP_CODE assembly, as well as any directory-level page and control assemblies that you can inspect with Reflector as shown in Figure 2. Also in this directory will be a set of .cs or .vb files that contain the generated ASP.NET classes that ASP.NET uses to compile the assemblies. The names for these assemblies and source files are randomly based on a hashcode, so you have to open them individually to find the one you’re interested in.
Full Pre-Compilation
The most common deployment scenario is full pre-compilation. In this model you use the ASPNET_COMPILER utility or the Web Site Publish feature inside of Visual Studio, which uses the same compilation APIs, to pre-compile your site in its entirety. This means that all markup pages (ASPX/ASCX/MASTER), CodeBeside classes, and all code in the APP_CODE directory are pre-compiled. The compiler takes the existing Web site and publishes the site to a new directory copying all files that relate to the Web sites including static files like images and CSS files. The compiler is essentially generating a complete copy of your Web site outputting a large number of compiled files in the BIN directory.
