c# - 当属性值更改时向 wpf Controller 添加事件

Question

我有属性(property)

public sealed partial class Computer
{
    private bool _online;
    public bool Online
    {
        get { return _online; }
        set
        {
            _online = value;
            RaiseProperty("Online");
        }
    }
 }

引发 INotifyPropertyChanged 类型的事件

public sealed partial class Computer : INotifyPropertyChanged
{
  public event PropertyChangedEventHandler PropertyChanged;

    private void RaiseProperty(string propertyName)
    {
        if (this.PropertyChanged != null)
        {
            this.PropertyChanged(this, new PropertyChangedEventArgs(propertyName));
        }
    }
 }

我的问题是，在这种情况下，我如何添加一个额外的事件来告诉 TabControl 在每次在线属性更改时运行特定的方法？

Answer 1

您需要向PropertyChanged 事件注册一个方法

MyComputer.PropertyChanged += Computer_PropertyChanged;

void Computer_PropertyChanged(object sender, PropertyChangedEventArgs e)
{
    if (e.PropertyName == "Online")
    {
        // Do Work
    }
}
