MVC学习笔记

CodeFirst生成数据库步骤
webconfig配置

<connectionStrings>
<add name="AuthorDesignContext" providerName="System.Data.SqlClient" connectionString="Data Source=.;Initial Catalog=AuthorDesign;Integrated Security=False;User Id=sa;Password=123456;MultipleActiveResultSets=True" />
</connectionStrings>

<configSections>
    <!-- For more information on Entity Framework configuration, visit http://go.microsoft.com/fwlink/?LinkID=237468 -->
    <section name="entityFramework" type="System.Data.Entity.Internal.ConfigFile.EntityFrameworkSection, EntityFramework, Version=6.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089" requirePermission="false" />
  </configSections>

包管理器

程序包管理器控制台输入Enable-migrations
然后输入add-migration AddDatabase（AddDatabase是数据库名）
最后输入Update-Database

model字段验证

/// <summary>
        /// 用户名
        /// </summary>
        [Required(ErrorMessage = "请输入用户名")]
        [StringLength(30, MinimumLength = 5, ErrorMessage = "请输入正确的用户名")]
        public string UserName { get; set; }
        /// <summary>
        /// 密码
        /// </summary>
        [Required(ErrorMessage = "请输入用密码")]
        [StringLength(30, MinimumLength = 5, ErrorMessage = "请输入正确的密码")]
        public string Password { get; set; }
        /// <summary>
        /// 验证码
        /// </summary>
        [Required(ErrorMessage = "请输入验证码")]
        [StringLength(6, MinimumLength = 6, ErrorMessage = "验证码错误")]
        public string ValidateCode { get; set; }
        /// <summary>
        /// 是否记住密码
        /// </summary>
        public bool IsRemind { get; set; }

@model AuthorDesign.Web.Areas.Admin.Models.LoginModel

//cshtml代码替换
<input type="text" class="form-control" placeholder="用户名" />
//替换
@Html.TextBoxFor(m=>m.UserName,new { @class= "form-control",@placeholder="用户名" })

//加入验证显示组件
@Html.ValidationMessageFor(m => m.UserName);
