Question

我正在尝试实现数据注释。我创建了一个名为 RegisterViewModel 的视图模型，其中包含以下数据注释。

namespace CSBSTest.ViewModel{public class RegisterViewModel
{
    [Required(ErrorMessage = "Filed is required")]

    public string Name { get; set; }
    [Required(ErrorMessage ="Filed is required")]
    [StringLength(9,ErrorMessage ="The Registeration number is not valid")]
    [RegularExpression("BCS15[1-9][1-9][1-9]",ErrorMessage ="The CUST reg number is not valid")]
    public string RegNo { get; set; }
    [Required(ErrorMessage = "Filed is required")]
    [EmailAddress]
    public string Email { get; set; }
    [Required(ErrorMessage = "Filed is required")]
    [MaxLength(11)]
    public string Phone { get; set; }
    [Required]
    [MinLength(6,ErrorMessage ="Minimun length must be 6 charccters")]
    public string Password { get; set; }
    [Required]
    [Compare("Password")]
    public string ConfirmPassword { get; set; }
}

}

然后我为RegisterViewModel创建了一个表单，如下所示：

@model CSBSTest.ViewModel.RegisterViewModel@{
ViewBag.Title = "SignupForm";
Layout = "~/Views/Shared/_NavBar.cshtml";}
<head>
<link href="~/Content/Site.css" rel="stylesheet" /></head>
<h2 id="head">
Let's get Started
</h2>
<form action="~/Home/SignUp" method="post" style="padding:70px">
    <div class="form-row">
    <div class="form-group col-md-3">
        <label for="inputEmail4">Full Name</label>
        <input type="text" class="form-control" id="inputEmail4" placeholder="Muhammad Ali" @Html.TextBoxFor(x => x.Name)
               @Html.ValidationMessageFor(x => x.Name)
    </div>
    <div class="form-group col-md-3">
        <label for="inputPassword4">Email</label>
        <input type="email" class="form-control" id="inputPassword4" placeholder="EaF@gmail.com" @Html.TextBoxFor(x => x.Email)
               @Html.ValidationMessageFor(x => x.Email)
    </div>

</div>
<div class="form-row">
    <div class="form-group col-md-3">
        <label for="inputEmail4">Password</label>
        <input type="password" class="form-control" @Html.TextBoxFor(x => x.Password)
               @Html.ValidationMessageFor(x => x.Password)
    </div>
    <div class="form-group col-md-3">
        <label for="inputAddress">Confirm Password</label>
        <input type="password" class="form-control" id="inputAddress" @Html.TextBoxFor(x => x.ConfirmPassword)
               @Html.ValidationMessageFor(x => x.ConfirmPassword)
    </div>


</div>
<div class="form-row">
    <div class="form-group col-md-3">
        <label for="inputAddress2">Cust Reg No</label>
        <input type="datetime" class="form-control" id="inputAddress2" placeholder="20 May 1996" @Html.TextBoxFor(x => x.RegNo)
               @Html.ValidationMessageFor(x => x.RegNo)
    </div>
    <div class="form-group col-md-3">
        <label for="inputAddress2">Phone Number</label>
        <input type="number" class="form-control" id="inputAddress2" placeholder="+92-3245009538" @Html.TextBoxFor(x => x.Phone)
               @Html.ValidationMessageFor(x => x.Phone)
    </div>
</div>

<div class="form-row">
    <div class="form-group col-md-3">
        @Html.Label("Dept", "Select Department")
        @Html.DropDownList("Department", new SelectList(new[] { "IT", "CS" }), new { @class = "form-control" })
    </div>
</div>
<br />
<button id="bt" type="submit" class="btn btn-primary">Register</button>


</form>

当我提交表单时，即使没有填写字段而没有显示注释消息，它也会被提交，或者它不会阻止提交空表单。我已经尝试在头部添加验证和无阻碍的库，但它仍然没有工作。任何帮助都非常感谢。谢谢提前

Answer 1

我认为这里的混淆是因为您正在使用<input>标记以及Html.TextBoxFor帮助程序。您不需要两者，Html.TextBoxFor方法实际上会为您生成输入标记。您可以向TextBoxFor提供其他参数，以使<input>代码包含class属性（以及您希望的任何其他属性）。

查看this tutorial以获取更多信息和良好示例。

我相信，如果你更正混合标签，你会发现验证开始有效。

我用Ctrl + F5运行项目，注释不起作用，也没有正确加载CSS。我重新启动了visual studio并在调试模式下运行了它正常工作的项目，非常感谢所有有回答和帮助的人。

1）请检查您的网站.config是否包含以下代码。

<appSettings>
   <add key="ClientValidationEnabled" value="true" />
   <add key="UnobtrusiveJavaScriptEnabled" value="true" />
</appSettings>

2）请检查您是否在项目的页面或布局页面中添加了以下Jquery文件的引用。 jquery.validate.unobtrusive.js和jquery.validate.js

数据注释验证在ASP.net中不起作用
