c# - Razor 无法识别 Html 类？

Question

所以我正在设计一个网页，接受用户输入，将其转换为电子邮件正文，然后将所述电子邮件发送到我的电子邮件帐户。我正在遵循 Microsoft 的指南:https://code.msdn.microsoft.com/Send-an-email-using-aspnet-80195a1f

它使用 @using (Html.BeginForm("email", "Home", FormMethod.Post)) 调用 ActionResult 方法，并将 html 表单本身放在 Html 的括号内。开始表格。这对我来说很有意义 - 直到我启动我的页面才看到我表单中的每个类由于某种原因都被 css 页面完全忽略了。我在 Html.BeginForm 括号外复制/粘贴了表单，然后 ta da!我的 CSS 又出现了。我已经阅读了一些关于我在这里尝试做的事情的不同教程/帖子，但听起来没有其他人真的遇到过这个问题......有什么想法吗？

作为引用，我的 html 页面是:

    @model CuttingEdgeWebsite2._0.Models.ServiceRequest

@using (Html.BeginForm("Email", "ServiceRequestsController", FormMethod.Post))
{
    <div class="servicesReq">
        <form class="serviceReqForm" action="mailto:carl@cuttingedgelighting.com?Subject=Service%20Request" method="post" enctype="text/plain">
            <div class="col-left">

我现在不能确定，但​​我相信错误和你在另一个中创建一个，Html.BeginForm 命令创建一个表单。

<div class="servicesReq">
@using (Html.BeginForm("Email", "ServiceRequestsController", FormMethod.Post, new { @class = "serviceReqForm" }))
{   <div class="col-left">
    <label>
        <span class="required">* </span><span>Name:</span><br />
        <input class="input" type="text" name="ServiceRequestName" required />
    </label><br />
    <label>
        <span class="required">* </span><span>Email:</span><br />
        <input class="input" type="text" name="ServiceRequestEmail" required />
    </label><br />
    <label>
        <span>Company:</span><br />
        <input class="input" type="text" name="ServiceRequestCompany" />
    </label><br />
    <label>
        <span>Address:</span><br />
        <input class="input" type="text" name="ServiceRequestAddress" />
    </label><br /><br />
</div>
    <div class="serviceTypeGrid">
        <span class="required">* </span><span>Please choose what type of servicing you require:</span><br /><br />
    </div>
    <div class="col-left2">
        <label class="serviceType">
            <input type="radio" name="serviceType" value="Electrical" /> Electrical<br />

            <input class="input" type="text" name="ServiceRequestNumber" />
        </label><br />
    </div>
    <label class="commentText">
