我可以在另一个类中继承"密码"数据注释吗?
public class AccountCredentials : AccountEmail
{
[Required(ErrorMessage = "xxx.")]
[StringLength(30, MinimumLength = 6, ErrorMessage = "xxx")]
public string password { get; set; }
}

另一类:
public class PasswordReset : AccountCredentials
{
[Required]
public string resetToken { get; set; }
**["use the same password annotations here"]**
public string newPassword { get; set; }
}

由于API调用,我必须使用不同的模型,但是要避免必须为同一字段维护两个定义.谢谢!
增加:类似的东西
[UseAnnotation[AccountCredentials.password]]
public string newPassword { get; set; }

{
public Password Password { get; set; }
}
public class PasswordReset : AccountCredentials
{
[Required]

public Password NewPassword { get; set; }
}
public class Password
{
[Required(ErrorMessage = "xxx.")]
[StringLength(30, MinimumLength = 6, ErrorMessage = "xxx")]
public string Value { get; set; }
public override string ToString()
{
return Value;
}

也许它对我来说已经成为一把金钥匙,但最近我在这方面取得了很大的成功,特别是在创建基类之间做出选择,或者改为采用共享行为并将其封装在对象中时.继承可能会很快失控.
