【转载】MVC2中自定义校验

新建一个Mvc2的应用程序；

在Models 文件夹下新建一个类EmailAttribute

 1 using System;
 2 using System.Collections.Generic;
 3 using System.Linq;
 4 using System.Web;
 5 using System.ComponentModel.DataAnnotations;
 6 
 7 namespace MvcTemp.Models
 8 {
 9     public class EmailAttribute: RegularExpressionAttribute
10     {
11         public EmailAttribute()
12             : base(@"^(\w)+(\.\w+)*@(\w)+((\.\w+)+)$")
13         {
14         }
15     }
16 }

复制代码

重新编译下项目，下面演示如何自定义使用这个标记

在Model文件夹下新建一个类Student

using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.ComponentModel.DataAnnotations;
using MvcTemp.Models;
namespace MvcTemp.Model
{
public class Student
    {
private int _id;
        [Required(ErrorMessage="必填")]
public int Id
        {
get { return _id; }
set { _id = value; }
        }
private string _name;
        [Required(ErrorMessage="必填")]
public string Name
        {
get { return _name; }
set { _name = value; }
        }
private string _emailAddress;
        [Email(ErrorMessage="错误的邮件地址")]
public string EmailAddress
        {
get { return _emailAddress; }
set { _emailAddress = value; }
        }
    }
}

复制代码

重新编译下项目，添加Controllers，

?

using System; using System.Collections.Generic; using System.Linq; using System.Web; using System.Web.Mvc;    namespace MvcTemp.Controllers {      public class StudentController : Controller      {          //          // GET: /Student/             public ActionResult Index()          {              return View();          }             //          // GET: /Student/Details/5             public ActionResult Details( int id)          {              return View();          }             //          // GET: /Student/Create             public ActionResult Create()          {              return View();          }              //          // POST: /Student/Create             [HttpPost]          public ActionResult Create(FormCollection collection)          {              try              {                  // TODO: Add insert logic here                     return RedirectToAction( "Index" );              }              catch              {                  return View();              }          }                     //          // GET: /Student/Edit/5              public ActionResult Edit( int id)          {              return View();          }             //          // POST: /Student/Edit/5             [HttpPost]          public ActionResult Edit( int id, FormCollection collection)          {              try              {                  // TODO: Add update logic here                      return RedirectToAction( "Index" );              }              catch              {                  return View();              }          }             //          // GET: /Student/Delete/5              public ActionResult Delete( int id)          {              return View();          }             //          // POST: /Student/Delete/5             [HttpPost]          public ActionResult Delete( int id, FormCollection collection)          {              try              {                  // TODO: Add delete logic here                      return RedirectToAction( "Index" );              }              catch              {                  return View();              }          }      } }

　　在Global.asax页中注册自己定义的标记

View Code

using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Web.Mvc;
using System.Web.Routing;
using MvcTemp.Models;
using System.ComponentModel.DataAnnotations;

namespace MvcTemp
{
// 注意: 有关启用 IIS6 或 IIS7 经典模式的说明，
// 请访问 http://go.microsoft.com/?LinkId=9394801

public class MvcApplication : System.Web.HttpApplication
    {
public static void RegisterRoutes(RouteCollection routes)
        {
            routes.IgnoreRoute("{resource}.axd/{*pathInfo}");

            routes.MapRoute(
"Default", // 路由名称
                "{controller}/{action}/{id}", // 带有参数的 URL
                new { controller = "Home", action = "Index", id = UrlParameter.Optional } // 参数默认值
            );

        }

protected void Application_Start()
        {
            AreaRegistration.RegisterAllAreas();
            DataAnnotationsModelValidatorProvider.RegisterAdapter(typeof(EmailAttribute), typeof(RegularExpressionAttributeAdapter));
            RegisterRoutes(RouteTable.Routes);
        }
    }
}

复制代码

   最后创建Student的Action视图即可
