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.
