Html.ActionLink 无法设置样式

Question

我想将我的 CSS 和 Bootstrap 与 MVC 结合起来，但我无法正确设置链接的样式。据我所知，我需要使用@Html.ActionLink 来重定向我的网页。有没有办法设置它的样式？

使用纯 CSS:

一切正常

<div class="mx-auto order-0">
        <a class="navbar-brand mx-auto" href="#">LIBRARY</a>
        <button class="navbar-toggler" type="button" data-toggle="collapse" data-target=".dual-collapse2">
            <span class="navbar-toggler-icon"></span>
        </button>
    </div>

这是我的 MVC：

<div class="mx-auto order-0">
            <a class="navbar-brand mx-auto" href="/Index">
                @Html.ActionLink("Library", "Index", "MyTemplate", null, new { @class = "mx-auto order-0" })
            </a>
            <button class="navbar-toggler" type="button" data-toggle="collapse" data-target=".dual-collapse2">
                <span class="navbar-toggler-icon"></span>
            </button>
        </div>

我也在 MVC 上测试过这个，但仍然没有样式：

@Html.ActionLink("Library", "Index", "MyTemplate", null, new { @class = "mx-auto order-0" })

我的 index.cshtml 文件如下所示：

@{
    ViewBag.Title = "Index";
    Layout = "~/Views/Shared/_MasterLayout.cshtml";
}

<h2>Index</h2>

我的控制器看起来像这样：

    public class MyTemplateController : Controller
    {
        // GET: MyTemplate
        public ActionResult Index()
        {
            return View("Index");
        }

        public ActionResult About()
        {
            return View("About");
        }

        public ActionResult Contact()
        {
            return View("Contact");
        }
    }
}

HTML 文件:

    <!doctype html>
<html lang="en">

    <title>@ViewBag.title</title>

很遗憾，样式不适用。我知道我可以这样做 @style 并以这种方式设置样式，但我希望所有样式都应用于 style.css 而不是在每个 class 中对其进行硬编码，因为它在我的代码中看起来很糟糕。请帮忙

Answer 1

如果你想要这个HTML:

<div class="mx-auto order-0">
        <a class="navbar-brand mx-auto" href="#">LIBRARY</a>
        <button class="navbar-toggler" type="button" data-toggle="collapse" data-target=".dual-collapse2">
            <span class="navbar-toggler-icon"></span>
        </button>
    </div>

那么你的 MVC 应该是这样的：

<div class="mx-auto order-0">
            @Html.ActionLink("Library", "Index", "MyTemplate", null, new { @class = "mx-auto order-0" })
            <button class="navbar-toggler" type="button" data-toggle="collapse" data-target=".dual-collapse2">
                <span class="navbar-toggler-icon"></span>
            </button>
        </div>

您正在将 Html.ActionLink（呈现为定位标签）包装在另一个标签中。而且你不能在 link.

中包含 link

或者，您也可以这样做（注意 a 标签的 href 是 Razor Url 助手）：

<div class="mx-auto order-0">
        <a class="navbar-brand mx-auto" href="@Url.Action("Index", "MyTemplate")">LIBRARY</a>
        <button class="navbar-toggler" type="button" data-toggle="collapse" data-target=".dual-collapse2">
            <span class="navbar-toggler-icon"></span>
        </button>
    </div>
