下面是写cookie
1 HttpCookie cookie = new HttpCookie("Info");//定义cookie对象以及名为Info的项
2 DateTime dt = DateTime.Now;//定义时间对象
3 TimeSpan ts=new TimeSpan(1,0,0,0);//cookie有效作用时间,具体查msdn
4 cookie.Expires = dt.Add(ts);//添加作用时间
5 cookie.Values.Add("user","cxbkkk");//增加属性
6 cookie.Values.Add("userid","1203"
);
7 Response.AppendCookie(cookie);//确定写入cookie中
读取cookie
1 if(Request.Cookies["Info"]!=null
)
2
{
3 string temp=Convert.ToString(Request.Cookies["Info"].Values["user"])+" "+Convert.ToString(Request.Cookies["Info"].Values["userid"
]);
4 //读全部就用Request.Cookies["Info"].Value)
5 if(temp==""
)
6
{
7 Response.Write("空"
);
8
}
9 else
10
Response.Write(temp);
11
}
12 else
13
{
14 Response.Write("error"
);
15 }
修改cookie
1 Response.Cookies["Info"]["user"] = "2"
;
2 Response.Cookies["Info"].Expires = DateTime.Now.AddDays(1);
删除cookie下的属性
1 HttpCookie acookie=Request.Cookies["Info"
];
2 acookie.Values.Remove("userid"
);
3 acookie.Expires = DateTime.Now.AddDays(1
);
4 Response.Cookies.Add(acookie);
删除所有cookie,就是设置过期时间为现在就行了
1 int limit=Request.Cookies.Count - 1
;
2 for(int i=0;i<limit;i++
)
3
{
4 acookie =
Request.Cookies(i)
5 acookie.Expires = DateTime.Now.AddDays(-1
)
6
Response.Cookies.Add(acookie)
7 }
