我正在尝试在我的MVC项目中使用Data Annotations(Mono/.NET 4.5).我创建了我的模型并添加了所有适当的注释.我的视图和控制器都有适当的连线.但是,验证似乎并没有发生.我已经尝试了一切我无法找到的东西.由于这是我第一次使用Razor和Data Annotations,我想有一些我不知道的设置部分,但我找不到它的生命.这是我的代码:
模型
using System;
using System.Collections.Generic;
using System.Linq;
using System.ComponentModel;
using System.ComponentModel.DataAnnotations;
using System.Web.Mvc;
namespace MyWebsite
{
public class RegisterViewModel : BaseViewModel
{
#region properties
[Required(ErrorMessage = "Required")]
[StringLength(50)]
[DisplayName("First Name")]
public string FirstName { get; set; }
[Required(ErrorMessage = "Required")]
[StringLength(100)]
[DisplayName("Last Name")]
public string LastName { get; set; }
[StringLength(50)]
[DisplayName("Display Name")]
public string DisplayName { get; set; }
[Required(ErrorMessage = "Required")]
[StringLength(255)]
[DisplayName("Email Address")]
public string EmailAddress { get; set; }
#endregion
#region ctor
public RegisterViewModel ()
{
}
#endregion
}
}

using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Web.Mvc;
namespace MyWebsite.Controllers
{
public class AccountController : Controller
{
public ActionResult Register()
{
ViewData ["IsComplete"] = false;
ViewData ["RequiredVouches"] = WebSettings.RequiredVouches;
return View ();
}
[HttpPost]
public ActionResult Register(FormCollection formData)
{
if (ModelState.IsValid) {
//TODO: Put the data
ViewData ["IsComplete"] = true;
}
return View ();
}
}
}
视图
@model SummerIsles.Web.RegisterViewModel
@section Styles {
<link href="~/Content/themes/base/Account.css" rel="stylesheet" type="text/css" />
}
@{
if((bool)@ViewData["IsComplete"]) {
<h1>Registration Request Complete!</h1>
<div class="page-message">
<p>
Confirmation message goes here
</p>
</div>
}
else {
<h1>Registration</h1>
<div class="page-message">
<p>
Instruction text goes here
</p>
</div>
using (Html.BeginForm()) {
@Html.ValidationSummary(false)
<fieldset>
<legend>Your Information</legend>
<div class="group column-1">
@Html.LabelFor(modelItem => @Model.FirstName)
@Html.EditorFor(modelItem => @Model.FirstName, new { htmlAttributes = new { @class="form-control" } } )
@Html.ValidationMessageFor(modelItem => @Model.FirstName)
@Html.LabelFor(modelItem => @Model.DisplayName)
@Html.EditorFor(modelItem => @Model.DisplayName, new { htmlAttributes = new { @class="form-control" } } )
@Html.ValidationMessageFor(modelItem => @Model.DisplayName)
</div>
<div class="group column-2">
@Html.LabelFor(modelItem => @Model.LastName)
@Html.EditorFor(modelItem => @Model.LastName, new { htmlAttributes = new { @class="form-control" } } )
@Html.ValidationMessageFor(modelItem => @Model.LastName)
@Html.LabelFor(modelItem => @Model.EmailAddress)
@Html.EditorFor(modelItem => @Model.EmailAddress, new { htmlAttributes = new { @class="form-control" } } )
@Html.ValidationMessageFor(modelItem => @Model.EmailAddress)
</div>
<div class="button-options">
<button id="btnSubmit" type="submit" formmethod="post" class="btn btn-danger">Submit</button>
<a id="btnCancel" href="~/" class="btn">Cancel</a>
</div>
</fieldset>
}
}
}
此外,我已将jquery验证脚本添加到我的布局文件中,并且还在web.confg中启用了客户端验证.
布局标题
<head>
<!--some other css and such-->
<script src="~/Scripts/jquery.validate.min.js"></script>
<script src="~/Scripts/jquery.validate.unobstrusive.min.js"></script>
</head>
Web.config文件
<appSettings>
<!--some other stuff-->
<add key="ClientValidationEnabled" value="true" />
<add key="UnobtrusiveJavaScriptEnabled" value="true" />
</appSettings>
基本上,当我点击提交时,它认为模型是完全有效的(ModelState.IsValid在控制器中返回true)和验证的东西(我希望在帖子回到控制器之前触发)似乎永远不会触发.即使使用完全空白的表单,我也没有得到验证消息(尽管有"必需"数据注释).我错过了什么？

@Html.ValidationMessageFor(modelItem => @Model.LastName)
应该
@Html.ValidationMessageFor(modelItem => modelItem.LastName)
适用于所有 HtmlHelpers,包括TextBoxFor和LabelFor等.
也
public ActionResult Register(FormCollection formData)
应该
public ActionResult Register(RegisterViewModel model)
为了让你的服务器端ModelState.IsValid工作.
