示例1: LibraryWindowViewModel
public LibraryWindowViewModel()
{
view = CollectionViewSource.GetDefaultView(LibraryItems);
LibraryItems = new System.Collections.ObjectModel.ObservableCollection<string>(iservice.Files);
iservice.Start();
iservice.FilesUpdated += new EventHandler<EventArgs<IList<string>>>(iservice_FilesUpdated);
this.PropertyChanged += (s, ea) =>
System.Diagnostics.Debug.WriteLine(ea.PropertyName + " changed to " +
this.GetType().GetProperty(ea.PropertyName).GetValue(this,null));
Observable.FromEventPattern<System.ComponentModel.PropertyChangedEventArgs>(this, "PropertyChanged")
.Where(et => et.EventArgs.PropertyName == "SearchString")
.Throttle(TimeSpan.FromMilliseconds(250))
.Subscribe(_ => {
System.Diagnostics.Debug.WriteLine("search string changed");
if (SearchString.Trim() == string.Empty)
view.Filter = null;
else
view.Filter = o => Regex.IsMatch(o as string, SearchString, RegexOptions.IgnoreCase);
view.Refresh();
FilteredLibraryItemsCount = LibraryItems.Where(o => Regex.IsMatch(o as string, SearchString, RegexOptions.IgnoreCase)).Count();
});
//Observable.FromEventPattern<System.ComponentModel.PropertyChangedEventArgs>(this, "PropertyChanged")
// .Where(et => et.EventArgs.PropertyName == "LibraryItems")
// .Do(et => view = CollectionViewSource.GetDefaultView(LibraryItems));
