将用户添加到数据库

Question

我收到错误：

  

InvalidOperationException ：实体类型＆＃39; 用户＆＃39;没找到。确保已将实体类型添加到模型中。

当我输入要添加到数据库的信息并提交我收到错误时，我可以让页面加载它。我通过 RegisterViewModel.cs 运行它，并带有指向 user.cs 的链接。表名是用户。希望有人能发现我确信我遗失的简单物品。

我发现很多人都有类似的错误，但不能解决我的问题。我已将User更改为User以匹配数据库以确保。我不知道它是否通过我的验证检查运行。

Homecontroller.cs

[HttpPost]
[Route("Register")]
public IActionResult Register(RegisterViewModel model)
{
    if (ModelState.IsValid)
    {
        Users NewPerson = new Users
        {
            FirstName = model.FirstName,
            LastName = model.LastName,
            EmailAddress = model.Email,
            Password = model.Password,
            CreatedAt = DateTime.Now,
            UpdatedAt = DateTime.Now,
        };

        _context.Add(NewPerson);
        // OR _context.Users.Add(NewPerson);
        _context.SaveChanges();
    }
    return View(model);
}

RegisterViewModles.cs

using System.ComponentModel.DataAnnotations;
namespace BankAccounts.Models
{
    public class RegisterViewModel : BaseEntity
    {
        [Required]
        [MinLength(2)]
        [RegularExpression(@"^[a-zA-Z]+$")]
        public string FirstName { get; set; }

        [Required]
        [MinLength(2)]
        [RegularExpression(@"^[a-zA-Z]+$")]
        public string LastName { get; set; }


        [Required]
        [EmailAddress]
        public string Email { get; set; }

        [Required]
        [MinLength(8)]
        [DataType(DataType.Password)]
        public string Password { get; set; }

        [Compare("Password", ErrorMessage = "Password and confirmation must match.")]
        public string PasswordConfirmation { get; set; }
    }
}

User.cs

using System;
namespace BankAccounts.Models
{
    public class Users : BaseEntity
    {
        public int UserId { get; set; }
        public string FirstName { get; set; }
        public string LastName { get; set; }
        public string EmailAddress { get; set; }
        public string Password {get; set;}
        public DateTime CreatedAt { get; set; }
        public DateTime UpdatedAt { get; set; }
    }
}
