C# MVC.Net自定义注册/登录错误“；salt的格式不是{int}.{string}"；

我需要你的帮助。我正在尝试在MVC.Net中进行自定义注册/登录，它使用SimpleCripto来加密密码。在我注册了一个用户之后，所有的内容都保存在我的中，似乎没有问题，但是当我尝试登录时，我得到了一个错误——“salt的格式不是预期的{int}.{string}”，它来自我的“IsValid”方法，在语句“if（user.Password==crypto.Compute（user.PasswordSalt，Password））”中。我将发布我的AuthenticationController以及注册和登录方法，如果您能指出问题所在以及如何解决，我将不胜感激。提前谢谢

请检查

crypto.Compute

函数参数。它需要textToHash（这是您的密码）和salt。您必须交换参数

您需要修改

IsValid

函数，如下所示：

private bool IsValid(string email, string password)
{
    var crypto = new SimpleCrypto.PBKDF2();
    bool IsValid = false;

    using (AppContext db = new AppContext())
    {
        var user = db.Users.FirstOrDefault(u => u.Email == email);
        if (user != null)
        {
            if (user.Password == crypto.Compute(password, user.PasswordSalt))
            {
                IsValid = true;
            }
        }
    }
    return IsValid;
}

谢谢你的快速回复。它做到了，但我没有足够的声誉给你投票！所以问题在于参数的顺序，对吗？再次感谢：）
