是否可以绑定到Properties.Settings.Default中的值？ [英] Is it possible to bind to a value in Properties.Settings.Default?

问题描述

是否可以绑定到Properties.Settings.Default中的一个值，以保持我的UI保存在那里的值？

Is it possible to bind to a value in Properties.Settings.Default in a way that will keep my UI current with the value stored there?

我有一个类：

public class FavoritePlayer
{
    public string Name
    {
        get
        {
            return wpfSample021.Properties.Settings.Default.FavoritePlayer.ToString();
        }
        set
        {
            wpfSample021.Properties.Settings.Default.FavoritePlayer = value;
        }
    }
}

在我的XAML中，我有一个资源：

In my XAML, I have a resource:

    <local:FavoritePlayer x:Key="fvPlayer"/>

和绑定：

    <Label DataContext="{DynamicResource fvPlayer}" Content="{Binding Path=Name}"/>

我希望数据绑定在任何时间更新属性的更改。有没有办法这样做？

What I would like is for the data-binding to update any time the property is changed. Is there a way to do this?

推荐答案

方便地为您， ApplicationSettingsBase 实现 INotifyPropertyChanged ，所以你只需要订阅 PropertyChanged 在 Properties.Settings.Default 并提出自己的 PropertyChanged 作为回应。

Conveniently for you, ApplicationSettingsBase implements INotifyPropertyChanged so you just need to subscribe to PropertyChanged on Properties.Settings.Default and raise your own PropertyChanged in response.
