c# - MVC2 验证模型也没有属性的验证属性

Question

我有一个模型:

public class OverdraftForm
{
    public string CustomerId { get; set; }
    public PaymentType PaymentType { get; set; }

    public OverdraftType Type { get; set; }

    public decimal PermanentAmount { get; set; }
    public int ExpirationPeriod { get; set; }

    public decimal OnetimeAmount { get; set; }
    public DateTime ExpirationDate { get; set; }
    public CreditType CreditType { get; set; }
    public string Comment { get; set; }
}

我的 Action 是

public ActionResult CreateOverdraft(OverdraftForm form)
{
    if (form.Type == OverdraftType.Permanent)
        return CreatePermanentOverdraft(form);
    return CreateOnetimeOverdraft(form);
}

重点是当我调试它时，即使在操作的第一行 ModelState.IsValid 是 false，它说 OnetimeAmount 应该有一个值。我正在使用 MVC2，我猜它的某些更改会导致此问题。

这是 MVC2 的一个变化 - on automatic databinding, it's going to read all your properties (even the read-only ones) to try to validate them .
