Let's say that I find a Asp.NET website on the internet and I want to find out the source code, is it possible? For example, can I find out the e-mails which is being used to send a message to a user on the website through the source code?

What I have tried:

Research, but people have not talked about this topic very much.

The email is not likely stored in the website code but rather in a config file or database so even if you could, you likely won't find what you are looking for.

If you're looking at the site from the browser-side, no it's not possible. The server will not give you the original .ASPX files or the .DLL's behind the site.

You'll have to get those files from the server over SMB. Good luck with that.

Once you have the .DLL's, they can be reversed back to some semblance of the original source, using .NET Reflector or similar.
