List <string> INotifyPropertyChanged事件

我有一个简单的类与一个字符串属性和List属性，我有INofityPropertyChanged事件实现，但当我做一个.Add添加到字符串列表这个事件没有命中，所以我的转换器显示在ListView没有被击中。我猜属性改变没有命中一个添加到列表....我怎么能实现这个方式来获得该属性更改事件命中？List <string> INotifyPropertyChanged事件

我是否需要使用其他类型的集合？

感谢您的帮助！

namespace SVNQuickOpen.Configuration 
{ 
    public class DatabaseRecord : INotifyPropertyChanged 
    { 
     public DatabaseRecord() 
     { 
      IncludeFolders = new List<string>(); 
     } 

     #region INotifyPropertyChanged Members 

     public event PropertyChangedEventHandler PropertyChanged; 

     protected void Notify(string propName) 
     { 
      if (this.PropertyChanged != null) 
      { 
       PropertyChanged(this, new PropertyChangedEventArgs(propName)); 
      } 
     } 
     #endregion 

     private string _name; 

     public string Name 
     { 
      get { return _name; } 

      set 
      { 
       this._name = value; 
       Notify("Name"); 
      } 
     } 

     private List<string> _includeFolders; 

     public List<string> IncludeFolders 
     { 
      get { return _includeFolders; } 

      set 
      { 
       this._includeFolders = value; 
       Notify("IncludeFolders"); 
      } 
     } 
    } 
}

您应该使用ObservableCollection<string>，而不是List<string>。在你的情况下，我只能使_includeFolders只读 - 你可以随时使用该集合的一个实例。

public class DatabaseRecord : INotifyPropertyChanged 
{ 
    private readonly ObservableCollection<string> _includeFolders; 

    public ObservableCollection<string> IncludeFolders 
    { 
     get { return _includeFolders; } 
    } 

    public DatabaseRecord() 
    { 
     _includeFolders = new ObservableCollection<string>(); 
     _includeFolders.CollectionChanged += IncludeFolders_CollectionChanged; 
    } 

    private void IncludeFolders_CollectionChanged(object sender, NotifyCollectionChangedEventArgs e) 
    { 
     Notify("IncludeFolders"); 
    } 

    ... 

}

这是钱！谢谢！ – theDoke

**为什么**应该使用'ObservableCollection'？ – C4u

@ C4u它可以用于WPF中的数据绑定（MVVM模式） – bniwredyc
