在ActionFilterAttribute中访问Session.SessionID

Question

我已经创建了Controller Attribute并且想要读取SessionId但是得到错误" An object reference is required for the non-static field, method, or property".从控制器属性访问会话对象的最佳方法是什么？

public class DetectChangesAttribute :ActionFilterAttribute
{
    public override void OnActionExecuting(ActionExecutingContext filterContext)
    {
        //I get error on Controller.Session.SessionID
        ConversionQueueModel.Remove(Controller.Session.SessionID, "");
        base.OnActionExecuting(filterContext);
    }
}

Answer 1

你试过这个吗？

filterContext.HttpContext.Session.SessionId
