MVC controller global variable from query string

Question

Is it possible to work with a global variable that need to receive the data from a query string in MVC controller?

public string Layout = Request.QueryString["Layout"];

At the moment I am working with a Session variable - but i want to use a global variable so it will be available all over my controller functions. Thanks

yes you can do it. But what i suggest you is. Declare a variable in controller and assign it in controller constructor. — Venkatesh Konatham

I have a certain page that i wish to redirect from with a parameter in the query string, this parameter should be received by the Controller and should be available through out the entire controller and functions. — Igal C

You may use TempData but don't forget to use the Keep() method to keep the data upon navigating from one controller to other. — Venkatesh

If you want global variable that will be global for all requests in your App you can use HttpContext.Application.

You can use it like this in any Controller method:

// set variable
HttpContext.Application["MyGlobalVar"] = 777; 
//get your variable
var myGlobalVar = Convert.ToInt32(HttpContext.Application["MyGlobalVar"])

Note that it stored like object so you should convert your variable when you get it.
