我有一个_Navigation.cshtml视图，我尝试使用Razor sf::Clock clock; // Initializing clock starts counting time.
while(someCondition)
{
sf::Time time = clock.getElapsedTime();
//It's going to execute do something() until time is higher than 10.0f
while(time.asSeconds() <= 10.0f)
{
//we need this to ensure that we won't fall into the infinite loop
time = clock.getElapsedTime();
do something()
//Optional: clock.restart(); If you want your code to be executed every x seconds.
}
}
和<ul> </ul>指令添加一些条件IsSectionDefined()标记。
但是，我收到以下异常：
@RenderSection()
正如您在下面的HTML代码段中所看到的，我可以非常轻松地将The file "~/Views/Shared/_Navigation.cshtml" cannot be requested directly because it calls the "RenderSection" method.添加到@RenderSection("bobtest")视图中，但不能在_Layout.cshtml视图中添加：
来自.. \ Views \ Home \ Index.cshtml的片段：
_Navigation
这是我的_Layout.cshtml，它引入＆＃34; _Navigation＆＃34;，＆＃34; _TopNavbar＆＃34;和＆＃34; _Footer＆＃34;
@section bobtest{
<ul class="nav nav-second-level collapse @Html.IsSelected(controller: "Dashboards", cssClass: "in")">
<li class="@Html.IsSelected(action: "Dashboard_1")"><a href="@Url.Action("Dashboard_1", "Dashboards")">Dashboard v.1</a></li>
<li class="@Html.IsSelected(action: "Dashboard_2")"><a href="@Url.Action("Dashboard_2", "Dashboards")">Dashboard v.2</a></li>
<li class="@Html.IsSelected(action: "Dashboard_3")"><a href="@Url.Action("Dashboard_3", "Dashboards")">Dashboard v.3</a></li>
</ul>
以下是<div id="wrapper">
<!-- Navigation -->
@Html.Partial("_Navigation")
<!-- Page wraper -->
<div id="page-wrapper" class="gray-bg">
<!-- Top Navbar -->
@Html.Partial("_TopNavbar")
<!-- Main view -->
@RenderBody()
@RenderSection("bobtest", required: true) <!-- THIS WORKS... -->
<!-- Footer -->
@Html.Partial("_Footer")
</div>
<!-- End page wrapper-->
</div>视图的摘要：
_Navigation
这只会导致异常，所以我需要清楚一点如何将条件标签添加到我的_Navigation视图中。
