master.cshtml（仅限相关部分）

@if (IsSectionDefined("sidebar")) {
    <div id="two-col">
        @RenderBody()
    </div>
    <div id="sidebar">
        @RenderSection("sidebar")
    </div>
} else {
    <div id="one-col">
        @RenderBody()
    </div>
}

index.cshtml

@inherits Nancy.ViewEngines.Razor.NancyRazorViewBase<dynamic>
@{ Layout = "master.cshtml"; }

// html for body, doesn't use model

@section sidebar {
    @Html.Partial("/sidebars/sidebar.cshtml", Model)
}

sidebar.cshtml（示例部分）

<ul>
@foreach (var item in Model.Items)
{
    <li>@Html.Raw(@item.DisplayText)</li>
}
</ul>

Answer 1

我最近遇到了这个问题，但是链接到我的主布局页面。查看索引页面，它可能是两件事之一，例如我，母版页的路径或部分路径。如果删除部分URL上的前导斜杠或者主页位于共享文件夹中，请添加其URL的完整路径（不带前导斜杠或〜/）。

这是我找到解决方案的地方。 https://groups.google.com/forum/#!topic/nancy-web-framework/zRLth_hl2r8

在我们的案例中，问题是我们所指的视图缺少设置：

构建操作：内容

在调试模式下意味着文件正在从文件系统中读取，但在发布模式下运行时没有被复制到发布bin文件夹。

Nancy Razor部分视图无法在发布模式下呈现
