.net 在使用System.ComponentModel.DataAnnotations时，是否有禁用验证的方法？

不幸的是，这里的其他问题并没有回答我的问题，我希望在这个问题上有一点天才

目前的问题是我有一个域对象“GamePlayer”，它有许多DataAnnotation，用于对从UI传入的数据进行模型验证。这些工作是一种享受，并且是完全可测试的等等

然而，我们有一个数据库，其中的数据在几年内被允许随意增长，大约660000个用户帐户，我想说目前有20000到50000个帐户违反了我们在GamePlayer对象上制定的规则

因此，我希望能够做到的是仍然使用数据注释，但是能够在从数据库到模型填充的过程中“禁用”它们

我知道，如果我使用ModelMetaData，将验证属性存储在另一个类中，并将主类与[MetadataTypeOfGamePlayerMetadata]关联，我可以：

TypeDescriptor.AddProvider(new AssociatedMetadataTypeTypeDescriptionProvider(typeof(GamePlayer), typeof(GamePlayerMetadata)), typeof(GamePlayer));

因此，使用reverse.RemoveProvider来删除规则——这是可行的，尽管我不想使用ModelMetaData类，如果可以的话，可以将其全部保存在一个类中

希望不要太含糊其辞：

希望支持该案例的其他信息：

我希望验证被禁用

这有助于提供更多信息吗？

如果我问了一个糟糕的问题，很高兴有人寻求澄清。基本上，当使用[Required]和[StringLength]验证属性时，只是想寻找一种方法来禁用某些情况下的验证。您能提供一些域对象的示例代码吗？我想看看您是如何处理属性设置器上的验证的。您是否在setters上显式调用Validator.ValidateProperty？在上面添加了一些澄清代码-希望能有所帮助？如果我问了一个糟糕的问题，很高兴有人寻求澄清。基本上，当使用[Required]和[StringLength]验证属性时，只是想寻找一种方法来禁用某些情况下的验证。您能提供一些域对象的示例代码吗？我想看看您是如何处理属性设置器上的验证的。您是否在setters上显式调用Validator.ValidateProperty？在上面添加了一些澄清代码-希望这会有所帮助？

Address stuff = new Address();
stuff.DisableValidation();
