在我的应用程序中,我在_LayoutPage.cshtml中添加了一个导航栏。当我定义_NavigationBar.cshtml部分时,它作为的局部视图从每个视图加载。我还添加了可以正常运行的Bootstrap 3,但是我尝试使用一些图标,并且由于我尝试应用字体和自定义字形,因此ASP.NET要么停留在加载页面上而没有成功,要么最终出现错误:


  无法计算表达式,因为当前线程处于堆栈溢出状态


错误指出该行的navbar

string userrole = Model != null ? Model.UserRoles.First() : string.Empty;


下面的_NavigationBar.cshtml代码在更改后。我所做的是更改了线路:

<li>@Html.ActionLink("Home", "Index", "Home")</li>




<li><a href="@Html.Action("Index", "Home")"><span class="glyphicon glyphicon-home"></span></a></li>


在导航栏中显示“主页”图标仍在工作。但是,当我尝试将第46行从

<li>@Html.ActionLink("Login", "Login", "Account")</li>


对此

<a href="@Html.Action("Login", "Account")"><span class="glyphicon glyphicon-log-in"> Login</span></a>


页面停止加载。

最佳答案

@Html.Action()调用服务器上的方法并返回结果。在您的情况下,该结果是一个视图,该视图包含@Html.Action()然后被调用以返回该视图的另一个副本,该视图包含@Html.Action()然后被调用以返回该视图的另一个副本,依此类推,直到您会收到一个stackoverflow异常。

你需要改变

<a href="@Html.Action("Login", "Account")">




<a href="@Url.Action("Login", "Account")">


这将生成一个URL
