郁闷，昨天发了居然被我误删了，今天重新再发。
使用SortedList集合对象，方便的对DropdownList控件的下来列表元素进行按字母排序，汉字则按拼音首字母排序，这个功能还不错。
SortedList.aspx
<%@Page Language="c#" debug="true" %><script runat="server" Language="c#"> void Page_Load(object source, EventArgs e)
{
SortedList mySortedList = new SortedList(); mySortedList["张三"]="我是张三"; mySortedList["李四"]="我是李四"; mySortedList["王五"]="我是王五"; mySortedList["赵六"]="我是赵六"; if (!(Page.IsPostBack))
{
foreach (DictionaryEntry Item in mySortedList) { ListItem newListItem = new ListItem(); newListItem.Text = Item.Key.ToString(); newListItem.Value = Item.Value.ToString(); myDropDownList.Items.Add(newListItem);
} }
} void Click(object source, EventArgs e) { myLabel.Text = myDropDownList.SelectedItem.Value; }</script><html> <form runat="server"> Pick a word from the list: <asp:dropdownlist id="myDropDownList" runat="server" /> <asp:button id="myButton" runat="server" text="OK" Onclick="Click" /> <br /><br /> <b>Definition: </b> <asp:Label id="myLabel" runat="server" text="" /> </form></html>
