Asp.net mvc 如何从DB中获取用户数并在.NETCore中的按钮上显示

我想从我的数据库中获取用户数量，并想在按钮中显示该数量，那么如何在asp.net core中做到这一点

有关用户数，您可以尝试

public class HomeController : Controller
{
    private ApplicationDbContext _context;
    public HomeController(ApplicationDbContext context)
    {
        _context = context;
    }
    public IActionResult Index()
    {
        return View();
    }        

    public IActionResult About()
    {
        ViewData["UserCount"] = _context.Users.Count();
        ViewData["Message"] = "Hello Word";

        return View();
    }      
}

@{
    ViewData["Title"] = "About";

}
<h2>@ViewData["Title"].</h2>
<h3>@ViewData["Message"]</h3>

<p>Use this area to provide additional information.</p>
<button>@ViewData["UserCount"]</button>

要显示计数按钮，您可以尝试

public class HomeController : Controller
{
    private ApplicationDbContext _context;
    public HomeController(ApplicationDbContext context)
    {
        _context = context;
    }
    public IActionResult Index()
    {
        return View();
    }        

    public IActionResult About()
    {
        ViewData["UserCount"] = _context.Users.Count();
        ViewData["Message"] = "Hello Word";

        return View();
    }      
}

@{
    ViewData["Title"] = "About";

}
<h2>@ViewData["Title"].</h2>
<h3>@ViewData["Message"]</h3>

<p>Use this area to provide additional information.</p>
<button>@ViewData["UserCount"]</button>

@{
ViewData[“Title”]=“关于”；
}
@ViewData[“标题”]。
@ViewData[“消息”]
使用此区域可提供其他信息

@ViewData[“用户计数”]
