RedirectToAction带参数:

return RedirectToAction("Action","controller", new {@id=id});

这可能是几年前的事了，但无论如何，这也取决于你的全局。Asax映射路径，因为你可以添加或编辑参数，以适应你想要的。

eg.

Global.asax

    public static void RegisterRoutes(RouteCollection routes)
    {
        routes.IgnoreRoute("{resource}.axd/{*pathInfo}");

        routes.MapRoute(
            "Default", // Route name
            "{controller}/{action}/{id}", // URL with parameters
            //new { controller = "Home", action = "Index", id = UrlParameter.Optional 
            new { controller = "Home", action = "Index", id = UrlParameter.Optional,
                  extraParam = UrlParameter.Optional // extra parameter you might need
        });
    }

然后你需要传递的参数将更改为:

return RedirectToAction( "Main", new RouteValueDictionary( 
    new { controller = controllerName, action = "Main", Id = Id, extraParam = someVariable } ) );

RedirectToAction带参数:

return RedirectToAction("Action","controller", new {@id=id});

//How to use RedirectToAction in MVC

return RedirectToAction("actionName", "ControllerName", routevalue);

例子

return RedirectToAction("Index", "Home", new { id = 2});

我也有这个问题，如果你在同一个控制器中，一个很好的方法是使用命名参数:

return RedirectToAction(actionName: "Action", routeValues: new { id = 99 });

....

int parameter=Convert.ToInt32(Session["Id"].ToString());

....

return RedirectToAction("ActionName", new { Id = parameter });
