处理 MVVM SL4 中的数据库错误
简单示例：尝试将记录保存到数据库时发生错误。或者作业可能发生超时。
在 MVVM 中，这将发生在我的模型或数据库访问层中。 （优雅地）处理该错误的方法是什么？
谢谢，
斯科特
Quick example: An error occurred when attempting to save a record to a db. Or perhaps a timeout occurred on a job.
In MVVM, that's going to occur in my Model or DB Access layer. What's the method for handling that error (elegantly)?
Thanks,
Scott

有点大问题。
这也很大程度上取决于您的用户需求。
例如：
您是否只需要向用户表明出现了问题？
只需放置一个带有消息的属性，以及一个指示错误状态的属性，并使您的视图相应地更改自身。
您是否需要限制访问，直到可以修复某些问题？
您的虚拟机可以轻松禁用命令，直到您重新启动连接或采取其他措施。
也许如果您心里有一个场景，我可以更具体:)

Kinda of a big question.
Also it is very dependent on your user requirements.
For example:
Do you need just to show the user that something went wrong?
Simply put a property with a message, and a property to indicate a faulted state and have your View change itself accordingly.
Do you need to limit access until you can fix something?
Your VM can easily disable commands until you have re-initiated your connection or some other measure.
Perhaps if you have a scenario in mind, I can be more specific :)
