After various management interfaces of roles are implemented, the next step is to manage users. There are many interfaces for user management, which must be implemented as follows:

1 public interface IUserRoleStore<TUser> : IUserStore<TUser>, IDisposable where TUser : class2 3 public interface IUserPasswordStore<TUser> : IUserStore<TUser>, IDisposable where TUser : class4 5 public interface IQueryableUserStore<TUser> : IUserStore<TUser>, IDisposable where TUser : class

The first is about the user-role relationship interface, which defines several role-related methods.

The second is about the password, which defines methods such as reading and setting the user password.

The last one is about users. It defines methods such as adding, deleting, modifying, and querying users.

The specific code is as follows:

1 public class HDUserStore <TUser>: 2 IUserRoleStore <TUser>, 3 IUserPasswordStore <TUser>, 4 IQueryableUserStore <TUser> 5 where TUser: HDUser, new () 6 {7 /// <summary> 8 // store user list 9 /// </summary> 10 private readonly Dictionary <string, TUser> _ users = new Dictionary <string, TUser> (); 11 12 public IQueryable <TUser> Users 13 {14 get 15 {16 if (_ users. count = 0) 17 {18 // generate user 19 TUser user = Re AteNewUser ("1", "daxia", "qingdao"); 20 // Set user Role 21 user. roles. add (new HDUserRole () {UserId = "1", RoleId = "power"}); 22 _ users. add (user. id, user); 23 24 user = CreateNewUser ("2", "aspnet5", "mvc6"); 25 user. roles. add (new HDUserRole () {UserId = "2", RoleId = "admin"}); 26 _ users. add (user. id, user); 27} 28 return _ users. values. asQueryable (); 29} 30} 31 32 // <summary> 33 // generate user 34 /// </ Summary> 35 // <param name = "id"> </param> 36 // <param name = "name"> </param> 37 // <param name = "pwd"> </param> 38 // <returns> </returns> 39 private TUser CreateNewUser (string id, string name, string pwd) 40 {41 TUser user = new TUser (); 42 user. passWord = pwd; 43 user. id = id; 44 user. userName = name; 45 user. normalizedUserName = name. toUpper (); 46 PasswordHasher <TUser> hash = new PasswordHasher <TUser> (); 47 user. passwordHash = hash. hashPassword (user, user. passWord); 48 49 return user; 50} 51 52 public Task AddToRoleAsync (TUser user, string roleId, CancellationToken cancellationToken) 53 {54 user. roles. add (new HDUserRole {RoleId = roleId, UserId = user. id}); 55 return Task. fromResult (0); 56} 57 58 public Task <IdentityResult> CreateAsync (TUser user, CancellationToken cancellationToke N) 59 {60 _ users [user. id] = user; 61 return Task. fromResult (IdentityResult. success); 62} 63 64 public Task <IdentityResult> DeleteAsync (TUser user, CancellationToken cancellationToken) 65 {66 if (user = null |!

= Null); 134} 135 136 public Task <bool> IsInRoleAsync (TUser user, string roleName, CancellationToken cancellationToken) 137 {138 return Task. fromResult (user. roles. any (ur => ur. roleId = roleName); 139} 140 141 public Task RemoveFromRoleAsync (TUser user, string roleName, CancellationToken cancellationToken) 142 {143 var roleEntity = user. roles. singleOrDefault (ur => ur. roleId = roleName); 144 if (roleEn Tity!

The code itself is easy to understand. It should be noted that the role is also attached to the user while we generate the user. Of course, this can also be accessed through a custom database.
