使用INotifyPropertyChanged的静态属性.C#

Question

我正在尝试创建一个静态属性,其中INotifyPropertyChanged将更新DataGrid ComboBox对我绑定的任何更改.

我收到这个错误,

错误CS0026关键字'this'在静态属性,静态方法或静态字段中无效

通过我的搜索,我发现了为什么你不能在.Net的静态方法中使用关键字'this'？,但即使经历了一切,我仍然无法弄清楚如何让这个工作.

但是,我改变的任何东西都否定了我试图用INotifyPropertyChanged??? 创建一个静态属性？

我的代码:

private static List<string> _nursingHomeSectionListProperty;

public static List<string> NursingHomeSectionListProperty
{
    get { return _nursingHomeSectionListProperty; }
    set
    {
       _nursingHomeSectionListProperty = value;
       NotifyStaticPropertyChanged();
    }
}

而Property改变了处理程序

public static event PropertyChangedEventHandler StaticPropertyChanged;

public static void NotifyStaticPropertyChanged([CallerMemberName] string propertyName = null)
    {
        StaticPropertyChanged?.Invoke(this, new PropertyChangedEventArgs(propertyName));
    }

以下代码是我如何使用属性更改处理程序的非静态属性,

public event PropertyChangedEventHandler PropertyChanged;

public void NotifyPropertyChanged([CallerMemberName] string propertyName = null)
   {
       PropertyChanged?.Invoke(this, new PropertyChangedEventArgs(propertyName));
   }

Answer 1

只是通过null而不是this:

public static event PropertyChangedEventHandler StaticPropertyChanged;

private static void NotifyStaticPropertyChanged([CallerMemberName] string name = null)
{
    StaticPropertyChanged?.Invoke(null, new PropertyChangedEventArgs(name));
}
