使用INotifyPropertyChanged的静态属性。 C＃ [英] Static property using INotifyPropertyChanged. C#

问题描述

我正在尝试创建一个静态属性，其中 INotifyPropertyChanged 将更新对 DataGrid <$ c $所做的任何更改c>我要绑定的组合框。

I am trying create a static property where INotifyPropertyChanged will update any changes made to a DataGrid ComboBox that I am binding to.

我遇到此错误，

错误CS0026关键字'this'在静态属性，静态
方法或静态字段中无效

Error CS0026 Keyword 'this' is not valid in a static property, static method, or static field

通过搜索，我发现了这个，但是即使经过所有步骤，我仍然不知道如何使它起作用。

Through my searches I came upon this Why can't you use the keyword 'this' in a static method in .Net?, but even after going through everything I still can't figure out how to get this to work.

但是，我所做的任何更改仅使我无法尝试使用 INotifyPropertyChanged 来创建静态属性？

But, anything I change only negates that I am trying to make a static property with INotifyPropertyChanged???

我的代码：

private static List<string> _nursingHomeSectionListProperty;

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

属性已更改处理程序

public static event PropertyChangedEventHandler StaticPropertyChanged;

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

下面的代码是我如何将属性更改处理程序用于非静态属性，

And the below code is how I am using the property changed handler for non static properties,

public event PropertyChangedEventHandler PropertyChanged;

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

推荐答案

只需通过 null 而不是 this ：

public static event PropertyChangedEventHandler StaticPropertyChanged;

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