I'm trying to update a database by having the signed in user type a number and it adds that number from the database using the signin manager and usermanager. I want it to take the signed in user's account balance that's stored in the database and add it to the number they typed. Then i want to update the database with the combined number.
However, I'm stuck on how I would get the controller to use the sign in manager. With the razor page all I have to do is use
@inject SignInManager<CardUs> SignInManager and use
@inject UserManager<CardUs> UserManager and also import the Microsoft.AspNetCore.Identity
but when I try to use UserManager.GetUserAsync(User).Result.AccountBalance it throws a lot of errors.
One of them being:
Feature 'top-level statements' is not available in C# 8.0. Please use language version 9.0 or greater
So I updated from 8.0 to 9.0 but then that didn't work. Now it's saying
Cannot use local variable or local function 'SigninManager' declared in a top-level statement in this context
I tried looking at the Microsoft page but nothing came up. This is error code CS8801.
How do I use the signin manager and user manager variable inside the controller?
This project not finished. I haven't sent it to the database yet. All it does it take the user input and show it on the next screen
Code:
AccountController:
using Microsoft.AspNetCore.Authorization;
using Microsoft.AspNetCore.Identity;
using Card.Areas.Identity.Data;
using Microsoft.AspNetCore.Mvc;
using System;
using System.Collections.Generic;
using System.Linq;
using System.Threading.Tasks;
using Card.Models;
SignInManager<CardUs> SignInManager;
UserManager<CardUs> UserManager;
namespace Card.Controllers
{
[Authorize]
public class AccountController : Controller
{
private readonly TransactionConnection _tc;
public AccountController(TransactionConnection tc)
{
_tc = tc;
}
public IActionResult Index()
{
return View();
}
public IActionResult Transactions()
{
var results = _tc.TransactionHistory.ToList();
return View(results);
}
[HttpGet]
public IActionResult Deposit()
{
return View();
}
[HttpPost]
public IActionResult Deposit(DepositModel model)
{
int test = model.AccountBalance UserManager.GetUserAsync(User).Result.AccountBalance;
return Content($"this is how much you entered {test}");
}
public IActionResult Transfers()
{
return View();
}
}
}
Deposit.cshtml:
@model Card.Models.DepositModel
@{
ViewData["Title"] = "Deposit";
Layout = "~/Views/Shared/_Layout.cshtml";
}
<form asp-action="Deposit" asp-controller="Account">
<label asp-for="AccountBalance"></label>
<input asp-for="AccountBalance" placeholder="How much do you want"/>
<input type="submit"/>
</form>
DepositModel:
using Microsoft.AspNetCore.Identity;
using System;
using System.Collections.Generic;
using System.Linq;
using System.Threading.Tasks;
using Card.Areas.Identity.Data;
namespace Card.Models
{
public class DepositModel
{
public int AccountBalance { get; set; }
}
}
And here's how the sign in manager look on a razor page:
@using Microsoft.AspNetCore.Identity
@using Card.Areas.Identity.Data
@inject SignInManager<CardUs> SignInManager
@inject UserManager<CardUs> UserManager

I figured it out. I was setting it up wrong. I had to add it to the constructor, and I had to create and assign fields.
