今天接續昨天的內容，把會員管理頁面做一個收尾

使用者列表

這邊可以用 ViewModel 來呈現使用者列表

public class OnlineShopUserViewModel
{
    public OnlineShopUser User { get; set; }
    public string RoleName { get; set; }
}

public async Task<IActionResult> ListUsers()
        {
            List<OnlineShopUserViewModel> userViewModels = new List<OnlineShopUserViewModel>();
            var AllUsers = _userManager.Users.ToList();
            foreach (var user in AllUsers)
            {
                userViewModels.Add(new OnlineShopUserViewModel
                {
                    User = user,
                    RoleName = string.Join("", await _userManager.GetRolesAsync(user))
                });
            }

            return View(userViewModels);
        }

刪除使用者

[HttpGet]
public async Task<IActionResult> DeleteUser(string id)
{
    var user = await _userManager.FindByIdAsync(id);
    if (user == null)
    {
        return NotFound();
    }
    return View(user);
}

[HttpPost]
public async Task<IActionResult> DeleteConfirmed(string id)
{
    var user = await _userManager.FindByIdAsync(id);
    var result = await _userManager.DeleteAsync(user);
    if (result.Succeeded)
    {
        return RedirectToAction("ListUsers");
    }

    foreach (var error in result.Errors)
    {
        ModelState.AddModelError("", error.Description);
    }
    return View("ListUsers");
}

後台就先到這邊告一個段落，明天就來處理前台的部分吧
