在 ASP.NET MVC 中将参数从一个 controller 传输到另一个

Question

I need to transfer one parameter (string) that I create in one controller to another controller. Till today I used global variable and it worked fine, but now a few users use the application, so I can't verify that the parameter was not rewrite by other users. The parameter is unique. I tried to use HttpContext.Session, but cannot be used in another controller (just returns null).

Do you have any idea how to do it?

And also, is it possible to use one instance of HttpContext.Session in different controllers?

Thank you!

Create global static variable inside controller class.

public class HomeController
{
    public static string object_name { get; set; }
}

Now in another controller use DependencyResolver to initialize HomeController

public class MyController
{
    private readonly HomeController homeController = DependencyResolver.Current.GetService<HomeController>();
    
    homeController.object_name = "" //Set value
    var a = homeController.object_name; //Get value
}
