.netCore 5区域路由在RedirectToActionArea中不起作用，并作为查询字符串使用

Question

当我在asp.net core 5中使用以下命令时

return RedirectToAction("Index", "SystemUsersManagement", new { area = "admin" });

它不能正常工作并获取Status Code: 404; Not Found Error。和Area go作为查询字符串，如下所示

https://localhost:44322/SystemUsersManagement/Index?area=admin

哪里错了。

我的控制器：

[Area("Admin")]
public class SystemUsersManagementController : Controller
{
    public ActionResult Save()
    {
       //do something
        return RedirectToAction("Index", "SystemUsersManagement", new { area = "admin" });
    }
}

我的创业之路：

app.UseMvc(routes =>
            {
                routes.MapRoute(
            name: "areas",
            template: "{area:exists}/{controller=Home}/{action=Index}/{id?}"
          );
                routes.MapRoute(
                    name: "Default",
                    template: "{controller}/{action}/{id?}",
                    defaults: new { controller = "Home", action = "Login" }
                );
                routes.MapRoute("DefaultApiWithId", "Api/{controller}/{id?}");
                routes.MapRoute("DefaultApiWithAction", "Api/{controller}/{action}");
                routes.MapRoute("DefaultApiGet", "Api/{controller}", new { action = "Get" });
                routes.MapRoute("DefaultApiPost", "Api/{controller}", new { action = "Post" });
            });

也是在ConfigureService中。。

services.AddMvc(option=>option.EnableEndpointRouting=false).AddJsonOptions(options => {
                options.JsonSerializerOptions.PropertyNameCaseInsensitive = true;
                options.JsonSerializerOptions.PropertyNamingPolicy = null;
            });

确保在控制器中添加[Area]属性，如下所示：

[Area("Admin")]
public class SystemUsersManagementController : Controller
{
    public ActionResult Index()
    {
        return View();
    }
}

项目结构应如下所示：
