复制代码 代码如下:
<%@ Page Language="C#" AutoEventWireup="true" CodeFile="Default3.aspx.cs" Inherits="Default3" %>

}
Ajax调用的一般处理程序为：
复制代码 代码如下:
<%@ WebHandler Language="C#" Class="Suggest" %>
using System;
using System.Web;
using System.Linq;
using System.Xml;
using System.Xml.Linq;
public class Suggest : IHttpHandler
{
public void ProcessRequest(HttpContext context)
{
HttpResponse Response = context.Response;
Response.Charset = "gb2312";
Response.ContentEncoding = System.Text.Encoding.UTF8;
Response.ContentType = "text/plain";
Response.StatusCode = 200;
string start = context.Request.Params["word"].ToString();
Response.Write(GetSuggest(start));
Response.Flush();
}
public bool IsReusable
{
get
{
return false;
}
}
///
/// 获取响应字符串
///
/// 查询起始字符串
///
private string GetSuggest(string start)
{
XElement root = XElement.Load(AppDomain.CurrentDomain.SetupInformation.Applicationbase + "Suggest.xml");
System.Collections.Generic.IEnumerable
q = (from r in root.Elements()
where (r.Name).ToString().ToLower().StartsWith(start.ToLower())
select r.Name.ToString()).Take(5);
System.Text.StringBuilder sb = new System.Text.StringBuilder();
foreach (string w in q)
{
sb.Append(w + ";");
}
if (sb.Length != 0)
sb.Remove(sb.Length - 1, 1);
return sb.ToString();
}
}
其中xml文档其实也不是什么标准的xml文档，就是拿来存储数据，练习练习刚学的Linq to XML。由于不想建表，本人也许有点懒惰吧，xml文档内容都是随机产生的：所以下面的效果显示的结果都是随机生成的；不说了。来个图例：
