Often, we often use the session to determine if a user is logged in. There are also some temporary, important data to try to store in the session.In the page we can easily get the value of the session, but in the class you will encounter some problems. Also know by the following method to get.system.web.httpcontext.current.session["userinfo"];But today the method also failed.

Implement OOP using assembly
OOP and process-oriented are both ideas in programming, and paradigm is used for academic purposes. Someone once said that since cfront generates C code, you can implement OOP using C itself and even assembly, but there are too many things that need to be done manually. Indeed, the process orientation has been used in assembly design for a long time, and OOP has been at the same
