一般处理程序中使用Session

来自于：cqulyk
在一般处理程序中使用Session必须要继承IRequiresSessionState接口

using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Web.SessionState;
namespace 验证码
{
    /// <summary>
    /// Summary description for ValidateCheckCode1
    /// </summary>
    public class ValidateCheckCode1 : IHttpHandler,IRequiresSessionState
    {
        public void ProcessRequest(HttpContext context)
        {
            context.Response.ContentType = "text/plain";
            string checkCodeRequested = context.Request["checkCode"];
            string checkCodeInSession = (string)context.Session["CheckCode"];
            if (checkCodeRequested.Equals(checkCodeInSession))
            {
                context.Response.Write("{\"retrunCode\":" + 0 + "}");
            }
            else
            {
               context.Response.Write("{\"retrunCode\":" + -1 + "}");
            }
        }
        public bool IsReusable
        {
            get
            {
                return false;
            }
        }
    }
}
