管理员类：
using System; using System.Collections.Generic; using System.ComponentModel.DataAnnotations; using System.ComponentModel.DataAnnotations.Schema; using System.Linq; using System.Text; using System.Threading.Tasks; namespace AuthorDesign.Model { /// <summary> /// 管理员 /// </summary> public class Admin { /// <summary> /// 管理员ID（主键） /// </summary> [Key] public int Id { get; set; } /// <summary> /// 用户名 /// </summary> [StringLength(30)] [Column(TypeName="varchar")] public string AdminName { get; set; } /// <summary> /// 手机号码 /// </summary> [StringLength(11)] [Column(TypeName = "varchar")] public string Mobile { get; set; } /// <summary> /// 邮箱 /// </summary> [StringLength(100)] [Column(TypeName = "varchar")] public string Email { get; set; } /// <summary> /// 密码 /// </summary> [StringLength(120)] [Column(TypeName = "varchar")] public string Password { get; set; } /// <summary> /// 密码盐值 /// </summary> [StringLength(10)] [Column(TypeName = "varchar")] public string Salt { get; set; } /// <summary> /// 对应角色Id /// </summary> public int AuthoryId { get; set; } /// <summary> /// 添加时间 /// </summary> public DateTime CreateTime { get; set; } /// <summary> /// 是否超级管理员 /// </summary> public Byte IsSuperAdmin { get; set; } /// <summary> /// 上次登录时间 /// </summary> public DateTime LastLoginTime { get; set; } /// <summary> /// 上次登录地址 /// </summary> [StringLength(50)] [Column(TypeName = "nvarchar")] public string LastLoginAddress { get; set; } /// <summary> /// 上次登录端口基本信息 /// </summary> [StringLength(50)] [Column(TypeName = "varchar")] public string LastLoginInfo { get; set; } /// <summary> /// 上次登录Ip /// </summary> [StringLength(50)] [Column(TypeName = "varchar")] public string LastLoginIp { get; set; } public Admin(){ CreateTime = DateTime.Now; LastLoginTime = DateTime.Now; } } }
