MVC路线.MapRoute问题 [英] MVC routes.MapRoute issues

问题描述

我的ID =国家\城市"
我在表格中使用以下ActionLink:

Hi,
I have id = "country\city"
I''m using below ActionLink in a table:

@Html.ActionLink("change", "changeCity", new { id = item.myCountyCity })

但是因为我的ID每次单击链接时都有2个用反斜杠分隔的部分，因此出现错误.为了解决该问题，我编写了以下自定义路线:

but because my id has 2 sections separated by backslash every time I click on the link it gives me error. To resolve the problem I wrote this custom route:

routes.MapRoute(
"CityCountyRoute",
"{controller}/{action}/{id}",
 new { controller = "Home", action = "Index", county = "", id = "" });

但这条路线仍然无法使用，并且我仍然收到相同的错误.
谢谢您预先提供的帮助.

Still this route is not working and I’m still receiving same error.
Thank you for your help in advance

推荐答案

您有多种选择可以解决此问题.其中一些是:

1."\"不是网址友好字符.因此，在html中使用字符串时(例如，在"target"属性中)，您必须UrlEncode您的字符串.因此，请更改以下

You have multiple options to deal with this. Some of them are:

1. "\" is not a url friendly character. So you will have to UrlEncode your string when using it in html (for example in the "target" property). So changing the following

@Html.ActionLink("change", "changeCity", new { id = item.myCountyCity })

到

to

@Html.ActionLink("change", "changeCity", new { id = Server.UrlEncode(item.myCountyCity) })

在控制器上，在您的操作方法中，您将必须像"UrlDecode"一样. Server.UrlDecode(id).

2.您可以用"\"分隔输入，并为操作方法提供2个参数-国家和城市.所以你的动作方法看起来像是

On the controller, in your action method, you will have to "UrlDecode", like. Server.UrlDecode(id).

2. You can split your input by "\" and supply the action method with 2 parameters - country and city. So you action method would look like

public ActionResult Index(string country, string city)
{
   return View();
}

然后您的路线将为

And then your route will be

routes.MapRoute(
"CityCountyRoute",
"{controller}/{action}/{country}/{city}",
new { controller = "Home", action = "Index", county = @"\s+", city = @"\s+" });

国家和城市为非空字符串.现在，您可以将Html.ActionLink调用为

where country and city are non-empty strings. Now you could have your Html.ActionLink call as

@Html.ActionLink("change", "changeCity", new { country = item.myCountyCity.Split('\\').First(), city = item.myCountyCity.Split('\\').Last() })

更好的方法是在控制器中执行此操作，并将这些值保存在传递给视图的模型中.因为视图中的代码量越少越好！

希望这会有所帮助！

Even better way would be do this would be to do this in the controller and have these values in a model which is passed to the view. Because the lesser the amount of code in your views, better it is!

Hope this helps!
