在ashx文件中使用Session和QueryString

有三点需要注意：

1.命名空间中要加入using System.Web.SessionState；

2.接口名要加入IRequiresSessionState或IReadOnlySessionState；

3.不管是Session还是QueryString都要通过HttpContext来获取。

具体代码如下：

view sourceprint?

01	<%@ WebHandler Language="C#" Class="UploadHandler" %>

02

03	using System;

04	using System.IO;

05	using System.Net;

06	using System.Web;

07	using System.Web.SessionState;

08

09	public class UploadHandler : IHttpHandler, IRequiresSessionState

10

{

11

12	public void ProcessRequest (HttpContext context) {

13	context.Response.ContentType = "text/plain";

14	context.Response.Charset = "utf-8";

15

16	string str1 = context.Session["aaa"].ToString();

17	string str2 = context.Request.QueryString["bbb"].ToString();

18

}

19

20	public bool IsReusable {

21

get {

22	return false;

23

}

24

}

25

26

}
