Question

我需要更改MVC项目中的所有URL，到目前为止这一点非常简单 - 我只需要更改global.asax.cs文件中所有相应路由中的URL字符串.MapRoute（）。

特别是一个链接表现得很顽固，不会改变，我确定这是因为它是唯一一个带参数的链接。

有问题的mapRoute是：

routes.MapRoute(
            "Mortgage.GetThisRate",
            "mortgage-rates/mortgage-rate-details/{groupId}/{paymentType}/{mortgageValue}/{province}",
            new { controller = "Mortgage", action = "GetThisRate", paymentType = UrlParameter.Optional, mortgageValue = UrlParameter.Optional, province = UrlParameter.Optional },
            new { groupId = "\\d+", paymentType = "\\d+", mortgageValue = "\\d+", province = "\\d+" }
        );

调用此mapRoute的按钮是：

 @Html.OmnitureButton( Url.Action("GetThisRate", new { groupId = info.GroupId }), "<span class=\"payment\"></span><br />Get Details", new {@class = "orange"}, "events", "event3", "", "event3", "", "Mortgage LearnMore")

按下此按钮时，它请求的URL为：http://www.apps.mysite.net/Mortgage/GetThisRate/8/48/200000/1 - 完全忽略其mapRoute方法中的URL字符串，它似乎就是。

我已经尝试将此mapRoute（）放在global.asax.cs的顶部，以确保它不会被更高优先级的路由忽略，但同样的问题仍然存在。

任何了解MVC路由的人都能解开这里的错误吗？

忘记了groupId参数，应该是这样的（已经过测试并且工作正常）

routes.MapRoute(
        "Mortgage.GetThisRate",
        "mortgage-rates/mortgage-rate-details/{groupId}/{paymentType}/{mortgageValue}/{province}",
        new { controller = "Mortgage", action = "GetThisRate", groupId = UrlParameter.Optional, paymentType = UrlParameter.Optional, mortgageValue = UrlParameter.Optional, province = UrlParameter.Optional },
        new { groupId = "\\d+", paymentType = "\\d+", mortgageValue = "\\d+", province = "\\d+" }

要与帮助者建立链接，您必须指定要使用的路径名称

@Html.RouteLink("title of link", "Mortgage.GetThisRate", new { groupId = "8", paymentType = "48", mortgageValue = "200000", province = "1" })

所以，你的链接看起来像......

yoursite/mortgage-rates/mortgage-rate-details/8/48/200000/1

我看到你正在使用自定义控件，因此可以使用@ URL.RouteUrl生成操作网址并将其提供给自定义控件，例如html参数

@Url.RouteUrl("Mortgage.GetThisRate", new { groupId = "8", paymentType = "48", mortgageValue = "200000", province = "1" })

扩展回答 例子，你需要一个标题为“click me！”的动作链接，href到控制器“home”，动作“sayHello”，类属性“some_css”和html id“link_say_hello” 溶液

@Html.ActionLink("click me!", "sayHello", "home", null, new { id="link_say_hello", @class = "some_css"})

html输出

<a class="some_css" href="/home/sayHello" id="link_say_hello">click me!</a>

为什么attibute类有@ ???因为类是保留字，编译器将抛出以下错误编译器错误消息：CS1513：}预期请记住。

太棒了！但在这种情况下，您需要一个自定义路由，而不是默认的{controller} / {action}，并与您的自定义帮助程序一起使用所以这是需要@ URL.RouteLink并给href像html属性......

new {href = @Url.RouteUrl("Mortgage.GetThisRate", new { groupId = "8", paymentType = "48", mortgageValue = "200000", province = "1", id="link_say_hello", @class = "some_css" })}

输出

<a class="some_css" href="/mortgage-rates/mortgage-rate-details/8/48/200000/1" id="link_say_hello">click me!</a>

看起来像路线的名字＆＃34; Mortgage.GetThisRate＆＃34;与您在Action＆＃34; GetThisRate＆＃34;中使用的名称不匹配（也是自定义助手，因此可能会自动添加＆＃34;抵押。＆＃34;。

解决方案是使用Url.RouteUrl（）并将其返回值转储到Html.OmnitureButton（）中。 mapRoute（）可选参数需要更改为默认值，因为RouteUrl（）不适用于选项。

工作代码如下：

routes.MapRoute(
           "Mortgage.GetThisRate",
           "mortgage/mortgage-rate-details/{groupId}/{paymentType}/{mortgageValue}/{province}",
           new { controller = "Mortgage", action = "GetThisRate", paymentType = 48, mortgageValue = 200000, province = 1 },
           new { groupId = "\\d+", paymentType = "\\d+", mortgageValue = "\\d+", province = "\\d+" }
       );

按钮：

@{
  string x = Url.RouteUrl("Mortgage.GetThisRate", new { groupId = info.GroupId});
  @Html.OmnitureButton(x, "<span class=\"payment\"></span><br />Get Details", new {@class = "orange"}, "events", "event3", "", "event3", "", "Mortgage LearnMore")
 }
