c#中ObservableCollection 排序方法

之前用到的一段代碼,記錄一下

    public static class ObservableExtension
    {
        public static void Sort<TSource, TKey>(this Collection<TSource> source, Func<TSource, TKey> keySelector)
        {
            List<TSource> sortedList = source.OrderBy(keySelector).ToList();
            source.Clear();
            foreach (var sortedItem in sortedList)
                source.Add(sortedItem);
        }

        public static void Sort<T>(this ObservableCollection<T> collection) where T : IComparable
        {
            List<T> sortedList = collection.OrderBy(x => x).ToList();
            for(int i = 0;i<sortedList.Count();i++)
            {
                collection.Move(collection.IndexOf(sortedList[i]), i);
            }
        }
    }
