WP7 ObservableCollection排序

Question

我有一个集合：

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

然后我把4个元素放入其中（它显示正确），我尝试对它们进行排序

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

ShopList现在有4个null元素。 为什么这样，以及如何纠正代码？ 谢谢

Answer 1

这是正确的顺序：

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