比较密码并确认密码在我的代码中不起作用？

Question

比较密码并确认密码在我的代码中不起作用

 [Required]
 [StringLength(100, ErrorMessage = "The {0} must be at least {2} characters long.", MinimumLength = 6)]
 [DataType(DataType.Password)]
 [Display(Name = "Password")]
 public string Password { get; set; }

 [DataType(DataType.Password)]
 [Display(Name = "Confirm password")]
 [StringLength(100, ErrorMessage = "The Password didn't match.")]
 [Compare("Password")]
 public string ConfirmPassword { get; set; }

当我在确认密码中输入了错误的密码时，我在这里使用Compare属性来匹配我的密码并确认密码。

为了显示错误消息，当ConfirmPassword不正确时，您应该在Compare属性内（而不是StringLength属性内）指定错误消息：

[Compare("Password", ErrorMessage = "The Password didn't match.")]
public string ConfirmPassword { get; set; }

我也建议使用nameof来指定比较属性名称：

[Compare(nameof(Password), ErrorMessage = "The Password didn't match.")]
public string ConfirmPassword { get; set; }
