在ApplicationUser中保持用户锁定状态的最佳方法是什么？

public class ApplicationUser : IdentityUser
{
    public bool IsLocked { get; set; } = false;
    // 其他属性...
}

public class AccountController : Controller
{
    private readonly UserManager<ApplicationUser> _userManager;

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

    [HttpPost]
    [ValidateAntiForgeryToken]
    public async Task<IActionResult> Login(LoginViewModel model)
    {
        if (ModelState.IsValid)
        {
            var user = await _userManager.FindByNameAsync(model.UserName);
            if (user != null && await _userManager.CheckPasswordAsync(user, model.Password))
            {
                if (user.IsLocked)
                {
                    ModelState.AddModelError(string.Empty, "您的账户已被锁定，请联系管理员解锁。");
                    return View(model);
                }

                // 用户登录成功，执行其他操作...
            }
            else
            {
                ModelState.AddModelError(string.Empty, "无效的用户名或密码。");
            }
        }

        return View(model);
    }
}
