一.什么是Model验证

Asp.Net MVC 采用Model绑定为目标Action生成相应的参数列表,但是在Action方法执行前，还要对绑定的参数进行验证，我们就把这种带参数的验证称之为Model验证。

二.正文

   下面直接上简单Demo操作

   第一步：模型验证就要建Model 并加属性验证

1  public class Person
 2     {
 3         [Key]
 4         public int pid { get; set; } 
 5 
 6         [Required(ErrorMessage = "必填")]
 7         [StringLength(20, MinimumLength = 4, ErrorMessage = "{2}到{1}个字符")]
 8         [Display(Name = "用户名")]
 9         public string pname { get; set; }
10 
11         [Required(ErrorMessage = "必填")]
12         [Display(Name = "生日")]
13         [DataType(DataType.DateTime)]
14         public DateTime pbirthday { get; set; }
15 
16         [Required(ErrorMessage = "必填")]
17         [Display(Name = "地址")]
18         [StringLength(20, MinimumLength = 4, ErrorMessage = "{2}到{1}个字符")]
19         public string paddress { get; set; } 
20 
21         [Required(ErrorMessage = "必填")]
22         [Display(Name = "邮箱")]
23         [DataType(DataType.EmailAddress)]
24         public string Email { get; set; }
25     }

   第二步：配置模型验证需要的js

    首先打开  网站目录下App_Start文件夹----->BundleConfig.cs   （如果有的话就不用配置）

1  bundles.Add(new ScriptBundle("~/bundles/jquery").Include(
2                         "~/Scripts/jquery-{version}.js"));
3 
4             bundles.Add(new ScriptBundle("~/bundles/jqueryval").Include(
5                         "~/Scripts/jquery.unobtrusive*",
6                         "~/Scripts/jquery.validate*"));

    第三步：在布局页中进行引入
