c# - Session Management in MVC

Question

I am new in MVC. I am creating new WebApplication in MVC4 Razor. I want to maintain User Login session for all pages. Can any one Explain me how to maintain session for all views in MVC with small example.

Answer 1

Session management is simple. Session object is available inside MVC controller and in HttpContext.Current.Session. It is the same object. Here is a basic example of how to use Session:

Write

Session["Key"] = new User("Login"); //Save session value

Read

user = Session["Key"] as User; //Get value from session

Answering your question

if (Session["Key"] == null){
   RedirectToAction("Login");
}
