Question

我的实体框架工作模型状态验证不起作用我试了很多东西，但仍然无法正常工作？

代码=＆GT;

public class HomeController : Controller
{
    private TsmsDBContext db = new TsmsDBContext();

    [HttpGet]
    public ActionResult Index()
    {
        db.Users.ToList();
        return View();
    }

    [HttpPost]
    [ValidateAntiForgeryToken]
    public ActionResult Index([Bind(Include = "UserId,password")] User user)
    {
        Response.Write((user.UserId + user.password).ToString());

        if (ModelState.IsValid)
        {
            Response.Write((user.UserId+user.password).ToString());
        }

        return View(user);   
    }

}

http get index方法是用于显示登录页面？并且post仅用于获取用户ID和密码并显示它。但是用户ID和密码显示在if(ModelState.IsValid)之前？但在它之后它没有显示。我的一切都很好。但是不知道它为什么不起作用？

我的模型类USER =＆gt;

public class User
{
    [Key]
    [Required(AllowEmptyStrings = false, ErrorMessage = "User Id Cannot Be Empty")]
    [MaxLength(12, ErrorMessage = "You Have Exceed The Max length Of User ID which is [12] character")]
    [RegularExpression("[1-3]{2}-[0-9]{5}-[123]{1}|[1-3]{2}-[0-9]{7}-[123]{1}", ErrorMessage = "Invalid Id,It should [xx]-[xxxxx]-[x] or [xx]-[xxxxxxx]-[x]")]
    [Display(Name = "User ID")]
    public string UserId { get; set; }
    /// <summary>
    /// ////////
    /// </summary>
    [Required(AllowEmptyStrings = false, ErrorMessage = "Password Cannot Be Empty")]
    [MaxLength(20, ErrorMessage = "Password Max Length Is 20 Character")]
    [DataType(DataType.Password)]
    [Display(Name = "Password")]
    public string password { get; set; }
    /// <summary>
    /// ////////
    /// </summary>
    [Required(AllowEmptyStrings = false, ErrorMessage = "User Level Cannot Be Empty")]
    [MaxLength(100, ErrorMessage = "The Max Length For User Level Is 100 Character")]
    [Display(Name = "User Level")]
    public string level { get; set; }

    //relationship with other table----

    //public List<UserDetail> UserDetails { get; set; }
}

和我的索引视图=＆gt;

<form id="login-form" method="post" role="form" style="display: block;">
@Html.AntiForgeryToken()
@Html.ValidationSummary(true)
    <div class="form-group">
        @Html.TextBoxFor(model => model.UserId, new { @class = "form-control" , @placeholder = Html.DisplayNameFor(model => model.UserId)})
        @Html.ValidationMessageFor(model => model.UserId)
    </div>
    <div class="form-group">
        @Html.TextBoxFor(model => model.password, new { @class = "form-control" , @placeholder = Html.DisplayNameFor(model => model.password) })
        @Html.ValidationMessageFor(model => model.password)
    </div>
    <div class="form-group text-center">
        <input type="checkbox" tabindex="3" class="" name="remember" id="remember">
        <label for="remember"> Remember Me</label>
    </div>
    <div class="form-group">
        <div class="row">
            <div class="col-sm-6 col-sm-offset-3">
                <input type="submit" name="login-submit" id="login-submit" tabindex="4" class="form-control btn btn-login" value="Log In">
            </div>
        </div>
    </div>
    <div class="form-group">
        <div class="row">
            <div class="col-lg-12">
                <div class="text-center">
                    <a href="" tabindex="5" class="forgot-password">Forgot Password?</a>
                </div>
            </div>
        </div>
    </div>
</form>

我可能因为某些原因而无法工作。所以我试图改变=＆gt;

@using (Html.BeginForm()) {
}

处于标签状态但没有工作。我也删除了antiforgari令牌。但仍然无法正常工作？任何解决方案？

Answer 1

ModelState无效，因为level模型的user属性为null

将其添加到表单中的HTML：

@Html.HiddenFor(model => model.level)

Answer 2

您的模型状态中有1个错误。因为您在user的模型类level中创建了必需属性。但在您看来，您没有任何文本框或地点可以进入关卡。因此，在这种情况下，您的level属性为空。正如Sajal所说，你应该将它作为隐藏财产。或者您可以清除级别属性的错误。

ModelState验证不适用于httppost
