How to use HttpContext.Current.Session in static property of a abstract class.?

asp.net-mvc, c#

Solution

Your base class `Controller` specifies a HttpContext property itself. So, when using it in your derived class `ControllerBase`, the compiler thinks you want to refer to this property of the base class.

You could either make the property non-static, as wudzik suggested in the first comment. I guess this would be the cleaner way to do it.

If you need to keep this property static, you have to tell the compiler, that you want to use the `HttpContext` class of namespace `System.Web`:

public static string SesssionId
{
     get { return System.Web.HttpContext.Current.Session["SessionId"]; }
}

Problem

I have a ControllerBase abstract class and as below. ``` using System.Web; using System.Web.Mvc; public abstract class ControllerBase : Controller { public static string SesssionId { get { return HttpContext.Current.Session["SessionId"]; } } } ``` I am getting Error "object reference is required for the non-static field, method, or property 'System.Web.Mvc.Controller.HttpContext.get" However I have used the same in other static classes and have not got the above error. I wonder how the HttpContext is being accessable but not the current. Could anyone clarify me, what is wrong with the above.
