在生成的EF类中添加INotifyPropertyChange

问题描述

所以，我的课程是由EF自动生成的：

So, my classes are auto-generated by EF:

//------------------------------------------------------------------------------
// <auto-generated>
//    This code was generated from a template.
//
//    Manual changes to this file may cause unexpected behavior in your application.
//    Manual changes to this file will be overwritten if the code is regenerated.
// </auto-generated>
//------------------------------------------------------------------------------

namespace Testje.Models
{
    using System;
    using System.Collections.Generic;

    public partial class Ploeg
    {
        public Ploeg()
        {
        }

        public int Id { get; set; }
        public string Naam { get; set; }
        public string Icon { get; set; }
    }
}

当其中一个属性改变时，我会喜欢做一个notifypropertychange。这是可能的，而不是编辑这个生成的类？

When one of the properties change, I'd like to do a notifypropertychange. Is this possible somehow without editing this generated class?

推荐答案

这是可能的，但我强烈建议不要这样做！
在你的模型中添加INotifyPropertyChanged将导致一个
不好的分离问题。

It would be possible, but I strongly suggest to not do this!Adding INotifyPropertyChanged in your model will lead to abad separation of concerns.

使用事件突出显示模型已更改。
看看这是如何工作的：

Use events to highlight that the model has changed.Have a look here to see how this works: MSDN on standard event pattern

甚至更好：

在您的viewmodel中，实现INotifyProperty已更改。
让您的ViewModel听从模型中的事件，调整数据
并通过INotifyPropertyChanged将其推送到您的视图

In your viewmodel, implement INotifyProperty changed.Let your ViewModel than listen to the events from your model, adapt the dataand push it to your view through INotifyPropertyChanged
