如何使用VB.NET以相反的顺序对字典的键进行排序？

Dim dicItems As Dictionary(of Integer, String)

字典中的项目是：

1,cat
2,dog
3,bird

我希望订单是：

3,bird
2,dog
1,cat

Dim dicItems As New Dictionary(Of Integer, String)
With dicItems
  .Add(1, "cat")
  .Add(2, "dog")
  .Add(3, "bird")
End With

dim query = from item in dicItems
            order by item.Key descending
            select item

如果需要,还可以使用Lambda语法：

Dim query = dicItems.OrderByDescending(Function(item) item.Key)
