如何使用自定义IPasswordHasher

I实现IPasswordHasher

public class MyPasswordHasher : IPasswordHasher
{
    public string HashPassword(string password)
    {
        using (SHA256 mySHA256 = SHA256Managed.Create())
        {
            byte[] hash = mySHA256.ComputeHash(Encoding.UTF8.GetBytes(password.ToString()));
            StringBuilder hashSB = new StringBuilder();
            for (int i = 0; i < hash.Length; i++)
            {
                hashSB.Append(hash[i].ToString("x2"));
            }
            return hashSB.ToString();
        }
    }

    public PasswordVerificationResult VerifyHashedPassword(
      string hashedPassword, string providedPassword)
    {
        if (hashedPassword == HashPassword(providedPassword))
            return PasswordVerificationResult.Success;
        else
            return PasswordVerificationResult.Failed;
    }
}

我在IdentityConfig 中写入

manager.PasswordHasher = new MyPasswordHasher();

但是AccountController/Login中的CCD_ 1不使用MyPasswordHaser。

如何在Identity 2.1中使用它？

public class AppUserManager : UserManager<AppUser, int>
{
    public AppUserManager(AppUserStore a_store)
        : base(a_store)
    {
        _container = a_container;
        _emailService = _container.GetInstance<IEmailService>();
        PasswordHasher = new AppPasswordHasher();
    }
}

PasswordHasher = new MyPasswordHasher();
