参照我先前的职位<一个href=\"http://stackoverflow.com/questions/2450198/how-to-validate-two-properties-with-asp-net-mvc-2\">How在ASP.NET MVC 2 ，我问我怎么能为模型验证比较两个属性来验证两个属性。

Referring to my earlier post How to validate two properties with ASP.NET MVC 2 where I asked how I could compare two properties for Model validation.

我没有找到答案有用的，但我留下了一个完全不同的问题：

I did find the answer useful, but I was left with an entirely different problem:

问题：如果房产级ValidationAttribute包含一个错误，那么类级别ValidationAttributes不验证

Problem: If a Property-level ValidationAttribute contains an error, then the Class-level ValidationAttributes are NOT validated.

请考虑以下几点：

[EqualTo("Email", "EmailConfirm", ErrorMessage = "E-mailadresserne skal være ens")]
[EqualTo("Password", "PasswordConfirm", ErrorMessage = "Adgangskoderne skal være ens")]
[Bind(Exclude="UserId")]
public class EditSiteUser
{
    [Required(ErrorMessage="Du skal bekræfte adgangskode")]
    public string PasswordConfirm { get; set; }

    [Required(ErrorMessage="Du skal bekræfte e-mailadressen")]
    [Email(ErrorMessage="Ugyldig e-mailadresse")]
    public string EmailConfirm { get; set; }
    public int UserId { get; set; }

    [Required(ErrorMessage = "Du skal indtaste et brugernavn")]
    public string Username { get; set; }

    [Required(ErrorMessage = "Du skal indtaste en adgangskode")]
    public string Password { get; set; }

    [Required(ErrorMessage = "Du skal indtaste en e-mailadresse")]
    [Email(ErrorMessage = "Ugyldig e-mailadresse")]
    public string Email { get; set; }
}

在这里，我有一个验证EmailConfirm和PasswordConfirm两个类级别attibutes。

Here I have two Class-level attibutes that validate EmailConfirm and PasswordConfirm.

如果像用户名的字段为空，这样会产生错误，那么这两个属性EqualTo从不验证。

If a field like Username is empty, and thus yields an error, then the two EqualTo Attributes are never validated.

有没有人有一个建议，解决这个问题？

Does anyone have a suggestion to overcome this problem?

编辑：如果您需要了解这个问题了，请问意见，我会很乐意给你所需要的任何其他信息

If you need anymore information about this problem, please ask in comments and I will be very happy to give you any additional information you need.

问：为什么很重要，如果一个属性级检查失败的类级检查得到验证？

Q: "Why is it important that the class-level checks get validated if a property-level check fails?".

答：因为这是一个形式，即用户输入的信息成一种形式，通过帖子后面AJAX表单时返回它应该显示当前所有问题的一部分。

A: "Because this is part of a form, where a user enters information into a form that posts back via AJAX. When the form returns it should show all current problems."

问：？？？？到底是什么EqualTo属性已放置在类它是一个自定义的验证属性，如果是这样，它是如何工作的？它有什么

Q: "What exactly is the EqualTo attribute you have placed on the class? Is it a custom validation attribute? If so, how does it work? what does it do?"

答：EqualTo是一类级别ValidationAttribute用于比较类实例的两个属性的值。查一查PropertiesMustMatchAttribute的一个类似的实现。

A: EqualTo is a class-level ValidationAttribute that compares the value of two Properties of the class-instance. Look up "PropertiesMustMatchAttribute" for a similar implementation.

推荐答案

这是不支持的。如果任何财产级验证失败，那么类级验证不执行。我建议你​​看一下 MVC万无一失验证的。它扩展了MVC验证添加的特遣队属性验证支持。我认为这将解决问题的这种特殊情况下。

This isn't supported. If any of the property level validations fail, then the class level validations are not performed. I suggest you look at MVC Foolproof Validation. It extends MVC validation to add support for contingent property validation. I think that would solve the problem for this particular case.

该项目选址指出，它不与MVC2 RC工作，所以你必须下载源$ C ​​$ c和让它运行/采纳他们的想法自己。

The project site states that it doesn't work with the MVC2 RC, so you'll have to download the source code and get it running/adopt their ideas yourself.
