Asp.net MVC 简单的Model验证

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     }
View Code

   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*"));
View Code

    第三步：在布局页中进行引入

 1 <!DOCTYPE html>
 2 <html>
 3 <head>
 4 <meta http-equiv="Content-Type" content="text/html; charset=utf-8"/>
 5     <meta charset="utf-8" />
 6     <meta name="viewport" content="width=device-width, initial-scale=1.0">
 7     <title>@ViewBag.Title - 我的 ASP.NET 应用程序</title>
 8     @Styles.Render("~/Content/css") 
 9     @Scripts.Render("~/bundles/jquery", "~/bundles/modernizr", "~/bundles/jqueryval")
10 </head>
11 <body>
12     <div class="navbar navbar-inverse navbar-fixed-top">
13         <div class="container">
14             <div class="navbar-header">
15                 <button type="button" class="navbar-toggle" data-toggle="collapse" data-target=".navbar-collapse">
16                     <span class="icon-bar"></span>
17                     <span class="icon-bar"></span>
18                     <span class="icon-bar"></span>
19                 </button>
20                 @Html.ActionLink("应用程序名称", "Index", "Home", new { area = "" }, new { @class = "navbar-brand" })
21             </div>
22             <div class="navbar-collapse collapse">
23                 <ul class="nav navbar-nav">
24                     <li>@Html.ActionLink("主页", "Index", "Home")</li>
25                     <li>@Html.ActionLink("关于", "About", "Home")</li>
26                     <li>@Html.ActionLink("联系方式", "Contact", "Home")</li>
27                 </ul>
28                 @Html.Partial("_LoginPartial")
29             </div>
30         </div>
31     </div>
32     <div class="container body-content">
33         @RenderBody()
34         <hr />
35         <footer>
36             <p>&copy; @DateTime.Now.Year - 我的 ASP.NET 应用程序</p>
37         </footer>
38     </div> 
39     @Scripts.Render("~/bundles/bootstrap")
40     @RenderSection("scripts", required: false)
41 </body>
42 </html>
View Code

   第四步：视图部分

 1 @model wahaha.Models.Person
 2 @{
 3     ViewBag.Title = "Index"; 
 4 }
 5 
 6 <h2>Index</h2>
 7 @using (Html.BeginForm())
 8 {
 9     <div class="form-horizontal">
10         <h4>用户注册</h4>
11         <hr />
12         @Html.ValidationSummary(true) 
13       <div class="form-group">
14             @Html.LabelFor(model => model.pname, new { @class = "col-md-2 control-label" })
15             <div class="col-md-10">
16                 @Html.EditorFor(model => model.pname)
17                 @Html.ValidationMessageFor(model => model.pname)
18             </div>
19         </div> 
20 
21         <div class="form-group">
22             @Html.LabelFor(model => model.pbirthday, new { @class = "col-md-2 control-label" })
23             <div class="col-md-10">
24                 @Html.EditorFor(model => model.pbirthday)
25                 @Html.ValidationMessageFor(model => model.pbirthday)
26             </div>
27         </div>
28 
29         <div class="form-group">
30             @Html.LabelFor(model => model.paddress,new { @class = "col-md-2 control-label" })
31             <div class="col-md-10">
32                 @Html.EditorFor(model => model.paddress)
33                 @Html.ValidationMessageFor(model => model.paddress)
34             </div>
35         </div>
36         <div class="form-group">
37             @Html.LabelFor(model => model.Email,new { @class = "col-md-2 control-label" })
38             <div class="col-md-10">
39                 @Html.EditorFor(model => model.Email)
40                 @Html.ValidationMessageFor(model => model.Email)
41             </div>
42         </div> 
43         <hr />
44         <div class="form-group">
45             <div class="col-md-offset-2 col-md-10">
46                 <input type="submit" value="注册" class="btn btn-default" />
47             </div>
48         </div>
49     </div>
50 }
