MVC 模型
MVC 模型包含所有应用程序逻辑(业务逻辑、验证逻辑、数据访问逻辑),除了纯视图和控制器逻辑。通过 MVC,模型可保存并操作应用程序数据。
Models 文件夹
Models 文件夹包含表示应用程序模型的类。
以登录验证为例,创建一个 AccountModels.cs 文件,用于应用程序安全的模型。
AccountModels 包含 LogOnModel、ChangePasswordModel 以及 RegisterModel。
LogOnModel:
public class LogOnModel { [Required] [Display(Name = "User name")] public string UserName { get; set; } [Required] [DataType(DataType.Password)] [Display(Name = "Password")] public string Password { get; set; } [Display(Name = "Remember me?")] public bool RememberMe { get; set; } }
RegisterModel:
public class RegisterModel { [Required] [Display(Name = "User name")] public string UserName { get; set; } [Required] [DataType(DataType.EmailAddress)] [Display(Name = "Email address")] public string Email { get; set; } [Required] [StringLength(100, ErrorMessage = "The {0} must be at least {2} characters long.", MinimumLength = 6)] [DataType(DataType.Password)] [Display(Name = "Password")] public string Password { get; set; } [DataType(DataType.Password)] [Display(Name = "Confirm password")] [Compare("Password", ErrorMessage = "The password and confirmation password do not match.")] public string ConfirmPassword { get; set; } }
ChangePasswordModel:
public class ChangePasswordModel { [Required] [DataType(DataType.Password)] [Display(Name = "Current password")] public string OldPassword { get; set; } [Required] [StringLength(100, ErrorMessage = "The {0} must be at least {2} characters long.", MinimumLength = 6)] [DataType(DataType.Password)] [Display(Name = "New password")] public string NewPassword { get; set; } [DataType(DataType.Password)] [Display(Name = "Confirm new password")] [Compare("NewPassword", ErrorMessage = "The new password and confirmation password do not match.")] public string ConfirmPassword { get; set; } }
添加数据库模型
在解决方案管理器中,右键点击 Models 文件夹,选择添加、类。
以添加MovieDB.cs 为例,
using System; using System.Collections.Generic; using System.Linq; using System.Web; using System.Data.Entity; namespace MvcDemo.Models { public class MovieDB { public int ID { get; set; } public string Title { get; set; } public string Director { get; set; } public DateTime Date { get; set; } } public class MovieDBContext : DbContext { public DbSet<MovieDB> Movies { get; set; } } }
添加数据库控制器
- 在解决方案资源管理器中,右键点击 Controllers 文件夹,然后选择添加、控制器。
- 把控制器名称设置为 MoviesController
- 选择模板:Controller with read/write actions and views, using Entity Framework
- 选择模型类:MovieDB (MvcDemo.Models)
- 选择 data context 类:MovieDBContext (MvcDemo.Models)
- 选择视图 Razor (CSHTML)
- 点击添加
Visual Studio 将创建如下文件:
- Controllers 文件夹中的 MoviesController.cs 文件
- Views 文件夹中的 Movies 文件夹
添加数据库视图
以下文件会被自动地在 Movies 文件夹中创建:
- Create.cshtml
- Delete.cshtml
- Details.cshtml
- Edit.cshtml
- Index.cshtml
