ASP.NET Core MVC：确认密码字段始终从模型状态返回错误

我有一个 Web 表单，用于捕获用户的一些详细信息以发送到后端。注册表单有一个名为的模型类RegisterModel，用于验证用户在该表单中输入的所有输入。当我输入满足所需条件的输入时，模型状态不会对其他字段抛出错误，但它会为确认密码字段抛出错误，即使该字段不为空并与之前的密码输入匹配。

RegisterModel：

[Required(ErrorMessage ="The password field is required")]
[MinLength(8, ErrorMessage ="The password needs to be at least eight characters long")]
[MaxLength(50, ErrorMessage ="The password length cannot exceed fifty characters")]
[RegularExpression("^(?=.*[a-z])(?=.*[A-Z])(?=.*\\W).+$", ErrorMessage = "Password must contain at least one uppercase letter, one lowercase letter, and one special character.")]
public string Password { get; set; }

[Required(ErrorMessage = "You have to confirm the password")]
[Compare("Password", ErrorMessage = "The passwords do not match")]
public string Confirmpassword {  get; set; }

        </div>
    </div>
</div>

以下是提交表单时我处理控制器逻辑的方式：

RegisterController：

public class RegisterController : Controller
{
    private readonly DatabaseContext databaseContext;

    public RegisterController(DatabaseContext dataContext)
    {
        databaseContext = dataContext;
    }

    public IActionResult CreateEntry(RegisterModel registerModel)
    {
        if (ModelState.IsValid) 
        {
            // return the account created successfully page
            // encrypt the password, since passwords are private
            var encryptedPassword = BCrypt.Net.BCrypt.HashPassword(registerModel.Password);
            var userName = registerModel.username;
            var email = registerModel.Email;

            // create a new database entity
            var entity = new User
            {
                Username = userName,
                Email = email,
                Password = encryptedPassword,
            };

            // make sure you are not adding duplicate entries
            var user = databaseContext.Users.Where(p=>p.Email == email).FirstOrDefault();

            if (user == null)
            {
                // entry does not exist, add a new one
                databaseContext.Add(entity);

                // save changes
                databaseContext.SaveChanges();

                return View("~Views/Home/Index");
            }
            else
            {
                // add errors to the model state and return the same view
                ModelState.AddModelError("Email", "That email is already taken"); 
                return View("~Views/Home/Register", registerModel);
            }
        }
        else
        {
            return View("~/Views/Home/Register.cshtml", registerModel);
        }
    }
}

当字段中有密码并且与密码字段中的输入匹配时，为什么我的表单会返回错误？
