我可以省略现场创作，如果我需要定制的getter / setter？ [英] can I omit field creation if I need custom getter/setter?

问题描述

我可以写这样的beatiful简单的代码：

 公众诠释三角洲{搞定;私人集; } 
  

现在我想补充只需一个电话 OnPropertyChanged（达美） ;

这是我知道如何做到这一点的唯一方法：

 公众诠释三角洲{{返回_delta; }私定
 {
 _delta =价值; OnPropertyChanged（达美）; } 
} 
私人诠释_delta; 
  

这是太多额外的代码！我为什么要在这种情况下，引进外地？你可以让这段代码更短？我想有这样的事情，但它不工作：

 公众诠释三角洲{搞定;私人集合{OnPropertyChanged（达美）; }} 
  

解决方案

没有你不能用自动性能做到这一点。自动性质，目的是要为在一个场的属性短手语法。它们几乎没有任何其他能力。任何自定义代码的执行需要一个完全成熟的属性。

I can write such beatiful straightforward code:

 public int Delta { get; private set; }

Now I want to add just one call OnPropertyChanged("Delta");

This is the only way I know how to do that:

public int Delta { get { return _delta; } private set
{
    _delta = value; OnPropertyChanged("Delta"); }
}
private int _delta;

It's too much extra-code! Why should I introduce field in this case? Can you make this code shorter? I would like to have something like that, but it doesn't work:

 public int Delta { get; private set { OnPropertyChanged("Delta"); } }

解决方案

No you cannot do this with auto-properties. Auto-properties are meant to be short hand syntax for a property over a field. They have virtually no other capabilities. Any custom code execution requires a full fledged property.
