参考链接：https://blog.csdn.net/huangshunle/article/details/7281683

1、创建用户类

?

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30

public class User    {        private int userId;        private string faceId;        private string userName;        private bool loginStatus = false;//登陆状态        private int userRoleId;          public int UserId { get => userId; set => userId = value; }        public string FaceId { get => faceId; set => faceId = value; }        public string UserName { get => userName; set => userName = value; }        public bool LoginStatus { get => loginStatus; set => loginStatus = value; }          public int UserRoleId { get => userRoleId; set => userRoleId = value; }          public static User _CurrentUser = null;          //应用单件模式，保存用户登录状态        public static User currentUser        {            get            {                if (_CurrentUser == null)                    _CurrentUser = new User();                return _CurrentUser;            }        }               }

　　2、登陆后添加用户信息

?

1 2 3

User.currentUser.UserName = "111"; User.currentUser.FaceId ="1";                       User.currentUser.LoginStatus = true;

　　3、使用

?

1 2 3 4

if (!User.currentUser.LoginStatus)//未登录 { //... }
