比较属性不起作用

Question

我有密码并使用比较属性确认密码字段，但它有问题？尝试通过 NuGet 包管理器更新所有内容，即使我输入“123456”，密码仍然不匹配，不知道我该怎么办？

  public class AccountsViewModel
    {
        public class Register
        {
            [Required]
            public string Username { get; set; }

            [Required]
            [DataType(DataType.Password)]
            public string Password { get; set; }

            [Compare("Password")]
            [DataType(DataType.Password)]
            public string ConfirmPassword { get; set; }

        }

    }

控制器

[HttpPost]
[ValidateAntiForgeryToken]
public async Task<ActionResult> Create([Bind(Include = "id,username,password")] AccountsViewModel.Register viewModel)
{
    if (ModelState.IsValid)
    {
        account account = new account();
        db.accounts.Add(account).username = viewModel.Username;
        db.accounts.Add(account).password = viewModel.Password;
        await db.SaveChangesAsync();
        return RedirectToAction("Index");
    }

    return View(viewModel);
}

查看

@model trainingmvc.Models.AccountsViewModel.Register

@{
    ViewBag.Title = "Create";
}

<h2>Create</h2>


@using (Html.BeginForm("Create", "Accounts", FormMethod.Post, new { @class = "form-horizontal", role = "form" }))

Answer 1

你的 POST 方法有一个[Bind] 属性

public async Task<ActionResult> Create([Bind(Include = "id,username,password")] AccountsViewModel.Register viewModel)

从绑定中排除模型ConfirmPassword属性，因此它的值为null，这是无效的（它与Password的值不匹配）因此添加了ModelState错误。

AccountsViewModel 是一个视图模型，视图模型永远不需要Bind 属性（因为视图模型只包含在视图中编辑的属性）。只需删除该属性，以便绑定所有属性并且您的模型将有效。
