global.asax中应用程序的物理路径

升级版
这是我现在的一个草图:

public class MvcApplication : System.Web.HttpApplication 
{
    ...
    protected void Application_Start()
    {
        AreaRegistration.RegisterAllAreas();

        RegisterRoutes(RouteTable.Routes);

        ControllerBuilder.Current.SetControllerFactory(typeof(IOCControllerFactory));
    }
}

public class IOCControllerFactory : DefaultControllerFactory
{
    private readonly IKernel kernel;

    public IOCControllerFactory()
    {
        kernel = new StandardKernel(new NanocrmContainer());
    }

    protected override IController GetControllerInstance(RequestContext requestContext, Type controllerType)
    {
        var controller = kernel.TryGet(controllerType) as IController;

        if (controller == null)
            return base.GetControllerInstance(requestContext, controllerType);

        var standartController = controller as Controller;

        return standartController;
    }

    class NanocrmContainer : Ninject.Modules.NinjectModule
    {
        public override void Load()
        {
            Bind<IFileService>().To<BusinessLogic.Services.FileService>().InRequestScope().WithConstructorArgument("temp", "Temp").WithConstructorArgument("docs", "Documents"); // Temp and Documents should be replaced with corresponding paths
        }
    }
}
