}

2. c#

using System;using System.Collections.Generic;using System.Linq;using System.Web;namespace WebApplication2{    /// <summary>    /// Handler1 的摘要說明    /// </summary>    public class Handler1 : IHttpHandler    {        public void ProcessRequest(HttpContext context)        {            context.Response.ContentType = "text/plain";            if (context.Request["data"] != null)             {                context.Response.Write("C#介面"+context.Request["data"].ToString());                return;            }            context.Response.Write("C#介面");        }        public bool IsReusable        {            get            {                return false;            }        }    }}
