Accessing ApplicationUser Property in the Login.cshtml.cs page

I'm developing web application using ASP.Net MVC Core. I used "Individual user authentication" so the identity table, Register and Login pages is generated by default.

I extended the identity table with enum column called "AccountStatus" that has Four values as following:

publicclassApplicationUser:IdentityUser{publicintStatusId{get;set;}publicstringStatusName{get;set;}publicAccountStatusIdAccountStatusId{get;set;}publicAccountStatusAccountStatus{get;set;}}publicenumAccountStatusId:int{Active=0,InActive=1,Expired=2,Pending=3}publicclassAccountStatus{publicAccountStatusIdAccountStatusId{get;set;}publicstringStatus{get;set;}publicList<ApplicationUser>Statuses{get;set;}}

I did the migration for the above code and I created 2 roles (Center and Admin).

publicclass SD{publicconststringAdminUser="Admin";publicconststringCenterUser="Center";}

so , I want in the Login.cshtml.cs below to check if the "AccountStatusId = AccountStatusId.Pending" then prevent the user from successful login and display a message "Waits for Approval".

But I'm not sure how can i access the field "AccountStatusId" which is in "ApplicationUser" model and check this field if "Pending" in Login.cshtml.cs page. Any help is appreciated.

Login.cshtml.cs

            _userManager = userManager;
