1、修改Api.cshtml文件
通过上述步骤，就能将组件WebAPITestClient引入进来。下面我们只需要做一件事：打开文件 (根据 Areas\HelpPage\Views\Help) Api.cshtml 并添加以下内容:

@Html.DisplayForModel("TestClientDialogs")
@Html.DisplayForModel("TestClientReferences")
添加后Api.cshtml文件的代码如下
*/

@using System.Web.Http
@using WebApiTestClient.Areas.HelpPage.Models
@model HelpPageApiModel

@{
    var description = Model.ApiDescription;
    ViewBag.Title = description.HttpMethod.Method + " " + description.RelativePath;
}

<link type="text/css" href="~/Areas/HelpPage/HelpPage.css" rel="stylesheet" />
<div id="body" class="help-page">
    <section class="featured">
        <div class="content-wrapper">
            <p>
                @Html.ActionLink("Help Page Home", "Index")
            </p>
        </div>
    </section>
    <section class="content-wrapper main-content clear-fix">
        @Html.DisplayForModel()
    </section>
</div>

@Html.DisplayForModel("TestClientDialogs")
@section Scripts{
    <link href="~/Areas/HelpPage/HelpPage.css" rel="stylesheet" />
    @Html.DisplayForModel("TestClientReferences")
}
