1.Demo下载：
文本框实现内容提示(仿Google、Baidu).rar
2.创建数据库、表（我用的sqlserver2008数据库）
复制代码 代码如下:
CREATE TABLE Ceshi
(
id VARCHAR(50) PRIMARY KEY NOT NULL,
cname VARCHAR(30)
)
GO
INSERT INTO Ceshi
SELECT NEWID(),'jack1' UNION
SELECT NEWID(),'jack2' UNION
SELECT NEWID(),'jack3' UNION
SELECT NEWID(),'jack4' UNION
SELECT NEWID(),'jack5' UNION
SELECT NEWID(),'peter1' UNION
SELECT NEWID(),'peter2' UNION
SELECT NEWID(),'peter3' UNION
SELECT NEWID(),'peter4' UNION
SELECT NEWID(),'peter5'
go
3.创建自定义函数
复制代码 代码如下:
create function [dbo].[f_GetPy](@str nvarchar(4000))
returns nvarchar(4000)
as
begin
declare @strlen int,@re nvarchar(4000)
declare @t table(chr nchar(1) collate Chinese_PRC_CI_AS,letter nchar(1))
insert into @t(chr,letter)
select '吖 ', 'A ' union all select '八 ', 'B ' union all
select '嚓 ', 'C ' union all select '咑 ', 'D ' union all
select '妸 ', 'E ' union all select '发 ', 'F ' union all
select '旮 ', 'G ' union all select '铪 ', 'H ' union all
select '丌 ', 'J ' union all select '咔 ', 'K ' union all
select '垃 ', 'L ' union all select '嘸 ', 'M ' union all
select '拏 ', 'N ' union all select '噢 ', 'O ' union all
select '妑 ', 'P ' union all select '七 ', 'Q ' union all
select '呥 ', 'R ' union all select '仨 ', 'S ' union all
select '他 ', 'T ' union all select '屲 ', 'W ' union all
select '夕 ', 'X ' union all select '丫 ', 'Y ' union all
select '帀 ', 'Z '
select @strlen=len(@str),@re= ' '
while @strlen> 0
begin
select top 1 @re=letter+@re,@strlen=@strlen-1
from @t a where chr <=substring(@str,@strlen,1)
order by chr desc
if @@rowcount=0
select @re=substring(@str,@strlen,1)+@re,@strlen=@strlen-1
end
return(@re)
end
GO
4.asp.net前台页面（需要添加2个引用：AjaxControlToolkit.dll，AutoCompleteExtra.dll）
复制代码 代码如下:
<%@ Page Language="C#" AutoEventWireup="true" CodeBehind="TextBoxAuto.aspx.cs" Inherits="WebApplication1.TextBoxAuto" %>

</form>
</body>
</html>
5.后台页面
复制代码 代码如下:
using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Web.UI;
using System.Web.UI.WebControls;
using Oceansoft.Net.Bll;
namespace WebApplication1
{
public partial class TextBoxAuto : System.Web.UI.Page
{
protected void Page_Load(object sender, EventArgs e)
{
}
[System.Web.Services.WebMethodAttribute(), System.Web.Script.Services.ScriptMethodAttribute()]
public static string[][] GetCompanyNameList(string prefixText, int count, string contextKey)
{
//获取自动完成的选项数据
List<string[]> list = new List<string[]>();
List<string> nameList = new List<string>();
List<string> idList = new List<string>();
CeshiManage ceshimanage = new CeshiManage();
ceshimanage.GetTopUserName(count, prefixText.ToUpper(), out idList, out nameList);
for (int i = 0; i < nameList.Count; i++)
{
string[] Respuesta = new string[2];
Respuesta[0] = nameList[i];
Respuesta[1] = idList[i];
list.Add(Respuesta);
}
return list.ToArray();
}
}
}

《魔兽世界》大逃杀！60人新游玩模式《强袭风暴》3月21日上线
暴雪近日发布了《魔兽世界》10.2.6 更新内容，新游玩模式《强袭风暴》即将于3月21 日在亚服上线，届时玩家将前往阿拉希高地展开一场 60 人大逃杀对战。
艾泽拉斯的冒险者已经征服了艾泽拉斯的大地及遥远的彼岸。他们在对抗世界上最致命的敌人时展现出过人的手腕，并且成功阻止终结宇宙等级的威胁。当他们在为即将于《魔兽世界》资料片《地心之战》中来袭的萨拉塔斯势力做战斗准备时，他们还需要在熟悉的阿拉希高地面对一个全新的敌人──那就是彼此。在《巨龙崛起》10.2.6 更新的《强袭风暴》中，玩家将会进入一个全新的海盗主题大逃杀式限时活动，其中包含极高的风险和史诗级的奖励。
《强袭风暴》不是普通的战场，作为一个独立于主游戏之外的活动，玩家可以用大逃杀的风格来体验《魔兽世界》，不分职业、不分装备（除了你在赛局中捡到的），光是技巧和战略的强弱之分就能决定出谁才是能坚持到最后的赢家。本次活动将会开放单人和双人模式，玩家在加入海盗主题的预赛大厅区域前，可以从强袭风暴角色画面新增好友。游玩游戏将可以累计名望轨迹，《巨龙崛起》和《魔兽世界：巫妖王之怒 经典版》的玩家都可以获得奖励。
