本文体验来自的DataAnnotationsExtensions.MVC3，是DataAnnotation的扩展，可以在客户端和服务端进行双重验证，能验证的类型包括：
● 邮件验证
● 整型验证 ● 日期验证 ● 数字验证(即从零开始的数字，不包括带小数点) ● 是否相同验证 ● 文件类型验证 ● int类型验证(可以是负的int类型) ● 最大数值验证(数值可以带小数点，可以对负数验证) ● 最小数值验证(数值可以带小数点，可以对负数验证) ● 数值验证(可以是负数，可以带小数点，就是不能是字符串) ● url地址验证 ● 年份验证 ......

● ● ● ● ● ● ● ● ● ● ●□ 安装
引用→右键→选择"管理NuGet程序包"→输入"DataAnnotationsExtensions"搜索→安装"DataAnnotationsExtensions.MVC3"
需要同时引入2个文件，DataAnnotationsExtensions用于服务端验证，DataAnnotationsExtensions.MV3用户客户端验证：
引入后，引用文件夹包括：
另外，不要被DataAnnotationsExtensions.MV3的名称疑惑，在MVC4下照样可以使用。
验证邮件、整型、最小数、文件类型
□ View Model
1: using System.ComponentModel.DataAnnotations;
2: using DataAnnotationsExtensions;
3:
4: namespace MvcApplication1.Models
5: { 6: public class Sample
7: { 8: [Email(ErrorMessage = "请输入有效邮箱")]
9: [Required(ErrorMessage = "必填")]
10: [Display(Name = "邮箱")]
11: public string Email { get; set; } 12:
13: [Integer(ErrorMessage = "必须为整数")]
14: [Min(1, ErrorMessage = "至少为1")]
15: [Display(Name = "年龄")]
16: public int Age { get; set; } 17:
18: [DataAnnotationsExtensions.FileExtensions("png|jpg|jpeg|gif", ErrorMessage = "允许的文件类型为png|jpg|jpeg|gif")] 19: [Display(Name = "文件类型")]
20: public string File { get; set; } 21: }
22: }
23:
□ 视图：必须包含与客户端验证相关的jquery,即@Scripts.Render("~/bundles/jqueryval")
1: @model MvcApplication1.Models.Sample
2:
3: @{ 4: ViewBag.Title = "Index";
5: Layout = "~/Views/Shared/_Layout.cshtml";
6: }
7:
8:Index
9:
10: @using (Html.BeginForm()) { 11: @Html.ValidationSummary(true)
12:
13:
14:
15:
16:
17: @Html.LabelFor(model => model.Email)
18:
19:
20: @Html.EditorFor(model => model.Email)
21: @Html.ValidationMessageFor(model => model.Email)
22:
23:
24:
25: @Html.LabelFor(model => model.Age)
26:
27:
28: @Html.EditorFor(model => model.Age)
29: @Html.ValidationMessageFor(model => model.Age)
30:
31:
32:
33: @Html.LabelFor(model => model.File)
34:
35:
36: @Html.EditorFor(model => model.File)
37: @Html.ValidationMessageFor(model => model.File)
38:
39:
40:
41:
42:
43:
44: }
45:
46:
47: @Html.ActionLink("Back to List", "Index") 48:
49:
50: @section Scripts { 51: @Scripts.Render("~/bundles/jqueryval") 52: }
53:
