推荐答案
首先是简短的listbox1，然后是简短的listbox2，然后将它们组合起来.
Firstly short listbox1 and after that short listbox2 and after that combine them.
<%@ Page Language="C#" AutoEventWireup="true"%>
<!DOCTYPE html>
<script runat="server">
protected void Page_Load(object sender, EventArgs e)
{
if(!Page.IsPostBack)
{
List<ListItem> list = new List<ListItem>(ListBox1.Items.Cast<ListItem>());
//sort list item alphabetixcally
listlist = list.OrderBy(x=> x.Text).ToList<ListItem>();
ListBox1.Items.Clear();
ListBox1.Items.AddRange(list.ToArray<ListItem>());
}
}
protected void ListBox1_SelectedIndexChanged(object sender, EventArgs e)
{
Label1.Text = "you selected....<br />";
Label1.Text += "item: " + ListBox1.SelectedItem.Text;
Label1.Text += "<br />value: " + ListBox1.SelectedItem.Value;
}
</script>

这个例子可能对您有帮助
this example may help you
private void SortListBox()
{
ArrayList ListBoxArray = new ArrayList();
int i = 0;
while (i < CarNameListBox.Items.Count)
{
ListBoxArray.Add(CarNameListBox.Items[i].Value);
++i;
}
CarNameListBox.Items.Clear();
ListBoxArray.Sort();
i = 0;
while(ListBoxArray.Count > i)
{
CarNameListBox.Items.Add(ListBoxArray[i].ToString());
++i;
}
}
