看代码基本就都能看懂了，增加了两个用户详细信息的表，角色表增加两个字段页面中实现树形显示。
//IdentityModels.csusing System.Data.Entity;using System.Security.Claims;using System.Threading.Tasks;using Microsoft.AspNet.Identity;using Microsoft.AspNet.Identity.EntityFramework;namespace WebDemo20150801.Models{ public class ApplicationUser : IdentityUser { public async Task<ClaimsIdentity> GenerateUserIdentityAsync(UserManager<ApplicationUser> manager) { var userIdentity = await manager.CreateIdentityAsync(this, DefaultAuthenticationTypes.ApplicationCookie); return userIdentity; } public virtual UserSetting UsersSetting { get; set; }//增加两个表用来显示用户数据 public virtual UserInfo UsersInfo { get; set; } } public class UserSetting { public string Id { get; set; } public string Theme { get; set; } } public class UserInfo { public string Id { get; set; } public string TrueName { get; set; } public string Phone { get; set; } } public class ApplicationRole : IdentityRole { public ApplicationRole() : base() { } public ApplicationRole(string name) : base(name) { } public ApplicationRole(string name, string description) : this(name) { this.Description = description; } public string Description { get; set; }//角色表里新增加的字段 public string ParentRole { get; set; } } public class ApplicationDbContext : IdentityDbContext<ApplicationUser> { public ApplicationDbContext() : base("DefaultConnection", throwIfV1Schema: false) { } public new IDbSet<ApplicationRole> Roles { get; set; }//一定要重写这个方法，不然能用，网页中也能获取数据，就是代码里点不出来~~ public static ApplicationDbContext Create() { return new ApplicationDbContext(); } }}
这是MVC5，MVC6看起来舒服多了，还能方便的修改ID为数字类型。
public class IdentityDbContext : IdentityDbContext<IdentityUser, IdentityRole, string> { }但是现在的版本需要这样
public class ApplicationDbContext : IdentityDbContext<ApplicationUser, ApplicationRole, string, ApplicationUserLogin, ApplicationUserRole, ApplicationUserClaim>
所以我放弃吧ID改成数字了。
这有ID变为数字的代码
