对于MVC中的循环不适用于不同的MapRoute

I'm new to MVC but I am fairly good with C#. So I was fiddling with MVC in Visual Studio where I came across this problem and I'm unable locate the cause of this error.

我是MVC的新手,但我对C#相当不错。所以我在Visual Studio中摆弄MVC,我遇到了这个问题,我无法找到导致此错误的原因。

I'm trying to print a variable n number of times. It works very well when i use the given URL

我正在尝试打印变量n次。当我使用给定的URL时,它工作得很好

http://localhost:18665/HelloWorld/Welcome?namelala=Rob&numtimes=3

The output is as expected -

This is Rob
This is Rob
This is Rob

However when I try the same with this URL

但是,当我尝试使用此URL时

The output is

输出是

My RouteConfig code :

我的RouteConfig代码:

namespace WebApplication1
{
    public class RouteConfig
    {
        public static void RegisterRoutes(RouteCollection routes)
        {
            routes.IgnoreRoute("{resource}.axd/{*pathInfo}");

            routes.MapRoute(
                name: "Default",
                url: "{controller}/{action}/{id}",
                defaults: new { controller = "Home", action = "Index", id = UrlParameter.Optional }


            );

            routes.MapRoute(
                name: "Name_Route",
                url: "{controller}/{action}/{numtimes}/{namelala}"

                );
        }
    }
}

HomeController Code

public ActionResult Welcome(string namelala, int numtimes=1)
        {
            ViewBag.Message = "This is " + namelala;
            ViewBag.numtimes = numtimes;

            return View();
        }

Welcome.cshtml Code

<h2>Welcome here</h2>
<ul>
    @{
        for (int i = 0; i < ViewBag.numtimes; i++)
        {
            <li>@ViewBag.Message</li>
        }

    }
</ul>

What am I doing wrong ?

我究竟做错了什么 ?

Change your route config to:

将您的路线配置更改为:

routes.MapRoute(
    name: "Name_Route",
    url: "{controller}/{action}/{namelala}/{numtimes}"
);

To match your method signature:

要匹配您的方法签名:

public ActionResult Welcome(string namelala, int numtimes=1)

And also, in line with Stephen's comment, move the route about the default route

而且,根据斯蒂芬的评论,移动关于默认路线的路线
