Question

这是AccountController.cs中的默认管理控制器

  public async Task<ActionResult> Manage(ManageUserViewModel model)
        {
            bool hasPassword = HasPassword();
            ViewBag.HasLocalPassword = hasPassword;
            ViewBag.ReturnUrl = Url.Action("Manage");
            if (hasPassword)
            {
                if (ModelState.IsValid)
                {
                    IdentityResult result = await UserManager.ChangePasswordAsync(User.Identity.GetUserId(), model.OldPassword, model.NewPassword);
                    if (result.Succeeded)
                    {
                        return RedirectToAction("Manage", new { Message = ManageMessageId.ChangePasswordSuccess });
                    }
                    else
                    {
                        AddErrors(result);
                    }
                }
            }
            else
            {
                ModelState state = ModelState["OldPassword"];
                if (state != null)
                {
                    state.Errors.Clear();
                }

                if (ModelState.IsValid)
                {
                    IdentityResult result = await UserManager.AddPasswordAsync(User.Identity.GetUserId(), model.NewPassword);
                    if (result.Succeeded)
                    {
                        return RedirectToAction("Manage", new { Message = ManageMessageId.SetPasswordSuccess });
                    }
                    else
                    {
                        AddErrors(result);
                    }
                }
            }

            return View(model);
        }

目前更新密码。但是，如果我想更改模型的用户名怎么办？我该如何修改这段代码？我知道一些编程，但我不知道修改这段代码？我欢迎任何帮助。感谢。

该操作看起来特定于更改密码。我将创建一个不同的操作和视图来修改您想要更改的其他字段，如用户名，电子邮件等。表用户可以通过身份上下文使用，因此您可以按照设置Get，View和Post的典型模式：

首先制作一个你想要编辑的视图模型：

public class UserUpdateViewModel
{
    [Required]
    [MaxLength(50)]
    public string UserName { get; set; }

    [Required]
    [MaxLength(50)]
    public string FirstName { get; set; }

    [Required]
    [MaxLength(50)]
    public string LastName { get; set; }

    [Required]
    [EmailAddress]
    [MaxLength(255)]
    public string Email { get; set; }
}

然后创建Get动作：

    [HttpGet]
    public ActionResult Edit(string id, ManageMessageId? message = null)
    {
        var user = _db.Users.First(u => u.UserName == id);
        // move entity fields to viewmodel from constructor, automapper, etc.        
        var model = new UserUpdateViewModel 
        {
            UserName = user.UserName,
            FirstName = user.FirstName,
            LastName = user.LastName,
            Email = user.Email
        };  
        ViewBag.MessageId = message;
        return View(model);
    }

然后制作一个视图，然后是帖子：

    [HttpPost]
    [ValidateAntiForgeryToken]
    public async Task<ActionResult> Edit(UserUpdateViewModel userUpdateViewModel)
    {
        if (!ModelState.IsValid) return View(userUpdateViewModel);

        var user = _db.Users.First(u => u.UserName == userUpdateViewModel.UserName);
        // Mapper.Map(userUpdateViewModel, user);  // move viewmodel to entity model
        // instead of automapper, you can do this:
        user.UserName = userUpdateViewModel.UserName;
        user.FirstName = userUpdateViewModel.FirstName;
        user.LastName = userUpdateViewModel.LastName;
        user.Email = userUpdateViewModel.Email;

        await _db.SaveChangesAsync();

        return this.RedirectToAction(a => a.Index()).WithSuccess("User updated.");
    }
