ASP.NETMVC模型驗證不適用于控制器建構式之一

我有用戶注冊、登錄和更新的模型驗證。但是模型驗證僅適用于登錄和注冊。更新函式也沒有反應 模型

namespace DDemo.Models
{
    public class SysUser

    {
        [Required(ErrorMessage = "Please enter User ID")]
        [Remote(action: "VerifyUserID", controller: "Account")]
        public string InvestorId { get; set; }

        [Required(ErrorMessage = "Please enter Password")]
        [StringLength(20, MinimumLength = 5, ErrorMessage = "Password must be 5 characters or more")]
        public string InvestorPw { get; set; }

        [Compare("InvestorPw", ErrorMessage = "Passwords do not match")]
        public string InvestorPw2 { get; set; }

        [Required(ErrorMessage = "Please enter Full Name")]
        public string FullName { get; set; }

        [Required(ErrorMessage = "Please enter Email")]
        [EmailAddress(ErrorMessage = "Invalid Email")]
        public string Email { get; set; } //@ sign 

        [Required(ErrorMessage = "Please enter Contact Number")]
        [RegularExpression(@"\d{8}", ErrorMessage = "Please enter 8 digit number")]
        public string Contact { get; set; }

        public DateTime LastLogin { get; set; }
    }
}

控制器

 [Authorize]
        [HttpPost]
        public IActionResult UserUpdate(SysUser user)
       {
            
            if (!ModelState.IsValid)
            {
                ViewData["Message"] = "Invalid Input";
                ViewData["MsgType"] = "warning";
                return View("UserUpdate", user);
            }
            else
            {
                string update =
                   @"
                UPDATE Investor 
                  SET InvestorPw = ('SHA1', '{1}'), FullName = '(2)', Email = '{3}', Contact = '{4}'  
                  WHERE InvestorId = '{0}'";

                int result = DBUtl.ExecSQL(update, user.InvestorId, user.InvestorPw, user.FullName, user.Email, user.Contact);

                if (result == 1)
                {
                    TempData["Message"] = "Account Updated";
                    TempData["MsgType"] = "success";
                }
                else
                {
                    TempData["Message"] = DBUtl.DB_Message;
                    TempData["MsgType"] = "danger";

uj5u.com熱心網友回復：

您必須修復視圖的表單標簽，將表單末尾移動到提交按鈕的下方并添加 @Html.ValidationSummary()

<form asp-controller="Account"
      asp-action="UserUpdate"
      method="post">

@Html.ValidationSummary(true) 

    <div class="form-group row">
        <div class="offset-sm-0 col-sm-4">
            <h2>Update Your Account</h2>
        </div>
    </div>

........

<div class="form-group row">
    <div class="offset-sm-2 col-sm-6">
        <input type="submit" value="Submit" class="btn btn-primary" />
    </div>
</div>

</form>
