MVC3 助手不工作，未找到
我在 /Helpers 下的主目录中创建了以下帮助程序：
HtmlHelpers.cs
using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Web.Mvc;
using System.Web.Mvc.Html;
namespace Website.Helpers
{
public static class HtmlHelpers
{
public static MvcHtmlString ActiveActionLinkHelper(this HtmlHelper Html, string text, string action, string controller, string activeClass = "active", bool actionCheck = false)
{
if (Html.ViewContext.RouteData.GetRequiredString("controller") == controller)
{
if (actionCheck)
{
if (Html.ViewContext.RouteData.GetRequiredString("action") == action)
return Html.ActionLink(text, action, controller, new { Class = activeClass });
}
else
{
return Html.ActionLink(text, action, controller, new { Class = activeClass });
}
}
return Html.ActionLink(text, action, controller);
}
}
}
我将命名空间添加到了 Publishers Areas 文件夹中的 Views web.config 中：
<system.web.webPages.razor>
<host factoryType="System.Web.Mvc.MvcWebRazorHostFactory, System.Web.Mvc, Version=3.0.0.0, Culture=neutral, PublicKeyToken=31BF3856AD364E35" />
<pages pageBaseType="System.Web.Mvc.WebViewPage">
<namespaces>
<add namespace="System.Web.Mvc" />
<add namespace="System.Web.Mvc.Ajax" />
<add namespace="System.Web.Mvc.Html" />
<add namespace="System.Web.Routing" />
<add namespace="Website.Helpers" />
</namespaces>
</pages>
</system.web.webPages.razor>
我不断收到此消息： 编译器错误消息：CS1061：“System.Web.Mvc.HtmlHelper”不包含“ActiveActionLink”的定义，并且找不到接受“System.Web.Mvc.HtmlHelper”类型的第一个参数的扩展方法“ActiveActionLink”（您是否缺少 using 指令或程序集引用？）
核心：@Html.ActiveActionLink("Dashboard", "Index", “仪表板”）
有谁知道我做错了什么？几乎没有任何关于如何或在何处存储 HTML 帮助器的教程。有人可以建议我吗？
I created the following helper in my main directory under /Helpers:
HtmlHelpers.cs
using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Web.Mvc;
using System.Web.Mvc.Html;
namespace Website.Helpers
{
public static class HtmlHelpers
{
public static MvcHtmlString ActiveActionLinkHelper(this HtmlHelper Html, string text, string action, string controller, string activeClass = "active", bool actionCheck = false)
{
if (Html.ViewContext.RouteData.GetRequiredString("controller") == controller)
{
if (actionCheck)
{
if (Html.ViewContext.RouteData.GetRequiredString("action") == action)
return Html.ActionLink(text, action, controller, new { Class = activeClass });
}
else
{
return Html.ActionLink(text, action, controller, new { Class = activeClass });
}
}
return Html.ActionLink(text, action, controller);
}
}
}
I added the namespace to the Views web.config in my Publishers Areas folder:
<system.web.webPages.razor>
<host factoryType="System.Web.Mvc.MvcWebRazorHostFactory, System.Web.Mvc, Version=3.0.0.0, Culture=neutral, PublicKeyToken=31BF3856AD364E35" />
<pages pageBaseType="System.Web.Mvc.WebViewPage">
<namespaces>
<add namespace="System.Web.Mvc" />
<add namespace="System.Web.Mvc.Ajax" />
<add namespace="System.Web.Mvc.Html" />
<add namespace="System.Web.Routing" />
<add namespace="Website.Helpers" />
</namespaces>
</pages>
</system.web.webPages.razor>
I keep getting this message:
Compiler Error Message: CS1061: 'System.Web.Mvc.HtmlHelper' does not contain a definition for 'ActiveActionLink' and no extension method 'ActiveActionLink' accepting a first argument of type 'System.Web.Mvc.HtmlHelper' could be found (are you missing a using directive or an assembly reference?)
Core: @Html.ActiveActionLink("Dashboard", "Index", "Dashboard")
Does anyone know what I am doing wrong? There are hardly any tutorials on how or where to store an HTML helper. Can someone please advise me?

核心：@Html.ActiveActionLink("Dashboard", "Index", "Dashboard") // 这里是问题所在
，因为你的方法是ActiveActionLinkHelper，你调用了不同的方法。
Core: @Html.ActiveActionLink("Dashboard", "Index", "Dashboard") // here it is the problem
as your method is ActiveActionLinkHelper, your calling different method.
编译器是对的。您的方法名为
ActiveActionLinkHelper。将其更改为ActiveActionLink一切都应该很好The compiler is right. You're method is named
ActiveActionLinkHelper. Change it toActiveActionLinkand all should be well
