MVVM通过ItemsSource获取CollectionView 并排序和筛选

void SortRecipeFolder<T>(IEnumerable<T> source, string sortName, ListSortDirection direction)

{

var collectionView = CollectionViewSource.GetDefaultView(source);

if (source is List<RemoteRecipeFolder> wafer)

{

collectionView.Filter = (x) =>

{

var casted = x as RemoteRecipeFolder;

return casted != null && casted.WaferId.Contains(SearchText, StringComparison.OrdinalIgnoreCase);

};

}

// 清除旧的排序

collectionView.SortDescriptions.Clear();

// 按 Age 升序排序

collectionView.SortDescriptions.Add(new SortDescription(sortName, direction));

// 如果需要，强制刷新

collectionView.Refresh();

}
