1 声明:HttpCookie MyCookie= new HttpCookie("test");
2增加:MyCookie.Values.Add("key1", "value1");//key1是键名,value1是值
3过期:MyCookie.Expires = DateTime.Now.AddDays(1);//一天之后过期。也可以设置一个负值,让Cookie立即失效
4添加到客户端:Response.AppendCookie(NewCookies);//用Response添加
5取值:
5.1 实例化:HttpCookie TestCookie = Request.Cookies["test"];//用Request取值,判断TestCookie为不为空,检测名为test的Cookie存不存在
5.2 取值:string CookieStr = TestCookie.Value;//获取单个Cookie值
string key1Str = TestCookie.Values["key1"]//获取名为test的Cookie的键名为key1的值
