我在做简单的Web应用程序在ASP.NET中，我想显示从菜单选项，但它不显示任何选项。在我在学校做的另一个应用程序中，它运行得很好。下面是我的代码，它不工作：
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="utf-8" />
<meta name="viewport" content="width=device-width, initial-scale=1.0" />
<title>@ViewData["Title"] - Blogic Project</title>
<link rel="stylesheet" href="~/lib/bootstrap/dist/css/bootstrap.min.css" />
<link rel="stylesheet" href="~/css/site.css" asp-append-version="true" />
@await RenderSectionAsync("Styles", required: false)
</head>
<body>
<header>
<nav class="navbar navbar-expand-sm navbar-toggleable-sm navbar-dark bg-dark border-bottom box-shadow mb-3">
<div class="container-fluid">
<a class="navbar-brand" asp-area="" asp-controller="Home" asp-action="Index">Blogic Project</a>
<button class="navbar-toggler" type="button" data-bs-toggle="collapse" data-bs-target=".navbar-collapse" aria-controls="navbarSupportedContent"
aria-expanded="false" aria-label="Toggle navigation">
<span class="navbar-toggler-icon"></span>
</button>
<div class="navbar-collapse collapse d-sm-inline-flex justify-content-between">
<ul class="navbar-nav flex-grow-1">
<li class="nav-item">
<a class="nav-link text-light" asp-area="" asp-controller="Home" asp-action="Index">Home</a>
</li>
<li class="nav-item">
<a class="nav-link text-light" asp-area="" asp-controller="Home" asp-action="Privacy">Privacy</a>
</li>
@{
@if (User.Identity.IsAuthenticated == false)
{
<ul class="navbar-nav navbar-right">
<li class="nav-item"><a class="nav-link text-light" asp-area="Security" asp-controller="Account" asp-action="Register"><span class="glyphicon"></span> Sign Up</a></li>
<li class="nav-item"><a class="nav-link text-light" asp-area="Security" asp-controller="Account" asp-action="Login"><span class="glyphicon glyphicon-log-in"></span> Login</a></li>
</ul>
}
else
{
<ul class="nav navbar-nav navbar-right">
<li class="nav-item dropdown">
<a class="nav-link dropdown-toggle" href="#" data-toggle="dropdown">Logged as @User.FindFirstValue(ClaimTypes.Name)</a>
<ul class="dropdown-menu dropdown-menu-dark">

</ul>

}

</div>

</header>
<div class="parallax">

<script src="~/lib/bootstrap/dist/js/bootstrap.bundle.min.js"></script>
<script src="~/lib/jquery/dist/jquery.min.js"></script>
<script src="~/js/site.js" asp-append-version="true"></script>
@await RenderSectionAsync("Scripts", required: false)
</body>
</html>问题就出在这个标签上：
<ul class="nav navbar-nav navbar-right">
<li class="nav-item dropdown">
<a class="nav-link dropdown-toggle" href="#" data-toggle="dropdown">Logged as @User.FindFirstValue(ClaimTypes.Name)</a>
<ul class="dropdown-menu dropdown-menu-dark">
<li class="nav-item"><a class="nav-link text-light" asp-area="Security" asp-controller="Account" asp-action="Logout"><span class="glyphicon glyphicon-log-out"></span> Logout</a></li>
</ul>
</li>
</ul>希望从另一个项目输出：
我还是一个学生，这是我第二次在ASP.NET中做一些事情。
谢谢
编辑：尝试在引导之前添加jquery，仍然不起作用。
编辑2：与这种变化一起工作
<script src="https://cdn.jsdelivr.net/npm/[email protected]/dist/jquery.min.js"></script>
<script src="https://cdn.jsdelivr.net/npm/[email protected]/dist/js/bootstrap.bundle.min.js"> </script>

你必须在Bootstrap之前使用jQuery。
你可以看到两个结果：

在ASP.NET Core中，使用Libman安装JQuery和Bootstrap 5后，在
_Layout.cshtml中添加以下内容：供参考https://getbootstrap.com/docs/5.0/components/dropdowns/
