用LINQ对ListBox ListItems排序? [英] Sorting a ListBox ListItems with LINQ?

问题描述

我正在尝试对列表框中的项目进行排序.但是，这样做后，项目值"将设置为项目文本".任何帮助将不胜感激.

I'm trying to sort the items in a ListBox. However, upon doing so the Item Value gets set to the Item Text. Any help would be appreciated.

lbxCustomers.DataSource = lbxCustomers.Items.Cast<ListItem>().Reverse().ToList();
lbxCustomers.DataBind();

推荐答案

可能首先应该将列表存储在通用集合中，然后对其进行排序.像这样:

May be first you should store the list in generic collection and then sort it. Something like this:

List<ListItem> list = new List<ListItem>(lbxCustomers.Items.Cast<ListItem>());
list = list.OrderBy(li => li.Text).ToList<ListItem>();
lbxCustomers.Items.Clear();
lbxCustomers.Items.AddRange(list.ToArray<ListItem>());
