Get variable value from another class

I want to save some variables for future reference so I declared a class Container.cs

public class Container
{
    public static String verifierCode;
}

and then I have my HomeController.cs where I update the Container's variables values: 

public class HomeController : Controller
{
    public ActionResult ValidateTwitterAuth()
    {
        Container.verifierCode = Request.Query.ElementAt(2).Value;
        //do some stuff
    }
    public String sendTweet(String NewTweet)
    {
        var userCreds = AuthFlow.CreateCredentialsFromVerifierCode(Container.verifierCode, Container.authorizationId);
        var user = Tweetinvi.User.GetAuthenticatedUser(userCreds);
        user.PublishTweet(NewTweet);
        return "sent!";
    }
}

It gets updated in the ValidateTwitterAuth with the specific values but when the sendTweet method is called the Container.verifierCode is null. I obviously tried to debug it but if I add the variable to quickwatch i get that

error CS0103: The name 'Container' does not exist in current context

Also, both the class and the container are in the same namespace. Any idea/tip why this is happening? I am just trying to declare a global variable which I can access from other classes/controllers.

I apologise if this may sound like a beginner question but I'm just starting to get my hands on asp.net

EDIT: From the answers, my way of handling with the problem was wrong. Therefore I installed the Microsoft.AspNetCore.Session NuGet Package and used it like this: 

 HttpContext.Session.SetString("verifierCode", Request.Query.ElementAt(2).Value);
 HttpContext.Session.SetString("authorizationId", Request.Query.ElementAt(0).Value);

and now it works. Thank you all for the answers!

You can store this data into session instead of class.as per below example

public class HomeController : Controller
    {
        public ActionResult ValidateTwitterAuth()
        {
            Session["verifierCode"] = Request.Query.ElementAt(2).Value;
            //do some stuff
        }
        public String sendTweet(String NewTweet)
        {
            var userCreds = AuthFlow.CreateCredentialsFromVerifierCode(Session["verifierCode"], Container.authorizationId);
            var user = Tweetinvi.User.GetAuthenticatedUser(userCreds);
            user.PublishTweet(NewTweet);
            return "sent!";
        }
    }

i have just change only verify code
