如何在.NET中检索已登录/已连接的用户列表？

Microsoft.AspNetCore.Identity
Microsoft.AspNetCore.Identity.EntityFrameworkCore

services.AddIdentity<ApplicationUser, IdentityRole>()
    .AddEntityFrameworkStores<ApplicationDbContext>()
    .AddDefaultTokenProviders();

using Microsoft.AspNetCore.Identity;

namespace YourApp.Models
{
    public class ApplicationUser : IdentityUser
    {
    }
}

using Microsoft.AspNetCore.Identity.EntityFrameworkCore;
using Microsoft.EntityFrameworkCore;
using YourApp.Models;

namespace YourApp.Data
{
    public class ApplicationDbContext : IdentityDbContext<ApplicationUser>
    {
        public ApplicationDbContext(DbContextOptions<ApplicationDbContext> options)
            : base(options)
        {
        }
    }
}

using System.Threading.Tasks;
using Microsoft.AspNetCore.Identity;
using Microsoft.AspNetCore.Mvc;
using YourApp.Models;

namespace YourApp.Controllers
{
    public class AccountController : Controller
    {
        private readonly UserManager<ApplicationUser> _userManager;

        public AccountController(UserManager<ApplicationUser> userManager)
        {
            _userManager = userManager;
        }

        public async Task<IActionResult> LoggedInUsers()
        {
            var users = await _userManager.GetUsersInRoleAsync("LoggedIn");
            return View(users);
        }
    }
}

@model IEnumerable<YourApp.Models.ApplicationUser>

<h2>Logged In Users</h2><table class="table">
   <thead>
        <tr>
            <th>Username</th>
            <th>Email</th>
        </tr>
    </thead>
   <tbody>
        @foreach (var user in Model)
        {
            <tr>
                <td>@user.UserName</td>
                <td>@user.Email</td>
            </tr>
        }
    </tbody>
</table>

endpoints.MapControllerRoute(
    name: "logged-in-users",
    pattern: "logged-in-users",
    defaults: new { controller = "Account", action = "LoggedInUsers" });
