WP7 ObservableCollection排序

Question

我有一个收藏：

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

然后，在我放入4个元素(它正确显示)之后，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个空元素。为什么会这样，以及如何更正代码？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);
