WP7 ObservableCollection排序

Question

我有一個集合：

public ObservableCollection<Shops> ShopList { get; set; }

然后我把4個元素放入其中（它顯示正確），我嘗試對它們進行排序

ShopList.Clear();
var orderedlist = ShopList.OrderBy(k => k.Name);
foreach (Shops s in orderedlist)
    ShopList.Add((Shops)s);

ShopList現在有4個null元素。 為什么這樣，以及如何糾正代碼？ 謝謝

Answer 1

這是正確的順序：

var orderedlist = ShopList.OrderBy(k => k.Name);
ShopList.Clear();
foreach (Shops s in orderedlist)
    ShopList.Add((Shops)s);
