asp.net-mvc 用于将一个属性与另一个属性进行比较的 MVC 数据注释？

MVC data annotation to compare one property to another?

提问by devlife

I've been playing around data annotations in MVC2 and am curious if there is an annotation to compare 2 properties (ie. password, confirm password)?

我一直在玩 MVC2 中的数据注释，并且很好奇是否有注释来比较 2 个属性（即密码、确认密码）？

If you are using ASP.Net MVC 3, you can use System.Web.Mvc.CompareAttribute

如果您使用的是 ASP.Net MVC 3，则可以使用 System.Web.Mvc.CompareAttribute

[Required]
[DataType(DataType.Password)]
public string Password { get; set; }

[Required]
[DataType(DataType.Password)]
[Compare("Password")]
public string PasswordConfirm { get; set; }

System.Web.Mvc.CompareAttribute has been deprecated.

System.Web.Mvc.CompareAttribute 已被弃用。

I was able to modify to work like this:

我能够修改为这样的工作：

    [Required]
    [DataType(DataType.Password)]
    [Display(Name = "Confirm password")]
    [System.ComponentModel.DataAnnotations.Compare("Password", ErrorMessage = "The password and confirmation password do not match.")]
    public string ConfirmPassword { get; set; }

There's not one built in, however, you can make your own. See this link, which shows the "PropertiesMustMatchAttribute" that does just what you're looking for.

没有内置的，但是，您可以自己制作。请参阅此链接，其中显示了符合您要求的“PropertiesMustMatchAttribute”。
