INotifyPropertyChanged 和自动属性 [英] INotifyPropertyChanged and Auto-Properties

问题描述

有没有办法将 INotifyPropertyChanged 与自动属性一起使用?也许是一个属性或其他东西，对我来说并不明显.

Is there a way to use INotifyPropertyChanged with auto-properties? Maybe an attribute or something other, not obvious to me.

public string Demo{
    get;set;
}

对我来说，自动属性将是一件非常实用的事情，但几乎总是，如果属性值已更改并且没有执行此操作的机制，我必须引发 PropertyChanged 事件，自动属性对我没用.

For me, auto-properties would be an extremely practicall thing, but almost always, I have to raise the PropertyChanged-event if the property value has been changed and without a mechanism to do this, auto-properties are useless for me.

推荐答案

没有内置机制来执行此操作.像 PostSharp 之类的东西可能会为你添加这样的东西(或 Mark Gravell 的 HyperDescriptor，如果您只是对让此数据绑定感知感兴趣).

There's no built-in mechanism to do this. Something like PostSharp would likely be able to add something like this for you (or Mark Gravell's HyperDescriptor, if you're just interested in making this databinding-aware).
