Your base class Controlleralready implements a property HttpContext.
您的基类Controller已经实现了一个属性HttpContext。
You can either reference it fully qualified: System.Web.HttpContext.Current...or use the Property of your controller, just like HttpContext.Session. For the second option, your method must be non-staticthough.
您可以引用它完全限定：System.Web.HttpContext.Current...或使用您的控制器的属性，就像HttpContext.Session. 对于第二个选项，您的方法必须是non-static。

One more reason for the error is that you can't use HttpContext.Current.Sessionand Server.MapPath()in static method
错误的另一个原因是您不能在静态方法中使用HttpContext.Current.Session和Server.MapPath()
In such case you can make use of HostingEnvironment.MapPath()
在这种情况下，您可以使用 HostingEnvironment.MapPath()
