c#中ObservableCollection<T>排序方法

之前用到的一段代码,记录一下

     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 = ;i<sortedList.Count();i++)
             {
                 collection.Move(collection.IndexOf(sortedList[i]), i);
             }
         }
     }
