            }).start();
        }
    }

    2. c#

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