C# javascript 读写Cookie的方法

第一：写cookies

response.cookies["username"].value="guest";
response.cookies["username"].expires=datetime.now.adddays(1);

第二：添加cookies

 httpcookie username_zhengshu_cookie = new httpcookie("uname");
        username_zhengshu_cookie.value = "陈xx";

        httpcookie userlession_zhengshur_cookie = new httpcookie("lcode");
        userlession_zhengshur_cookie.value = "chen jian ping";

        username_zhengshu_cookie.path = "/";
        userlession_zhengshur_cookie.path = "/";

//限定有效期
        userlession_zhengshur_cookie.expires = datetime.now.adddays(1);
        username_zhengshu_cookie.expires = datetime.now.adddays(1);

        response.cookies.add(userlession_zhengshur_cookie);
        response.cookies.add(username_zhengshu_cookie);

//cookies添加
 response.appendcookie(user_cookies);

//取值
response.write(request.cookies["uname"].value);

//javascript写读cookie
function set_cookie()
{
    var setvalue="陈xx";
    var exdate=new date();
    exdate.setdate(exdate.getdate()+365);
    document.cookie="userlession"+ "=" +setvalue+";expires="+exdate.togmtstring()+";path=/";
    alert("已经写入cookie");
}

 function get(){　     
   　　var cookiestring=new string(document.cookie)     
   　　var cookieheader = "userlession="     
   　　var beginposition = cookiestring.indexof(cookieheader)     
   　　if(beginposition != -1)
   　　{     
   　　　　alert(cookiestring.substring(cookieheader.length,cookiestring.indexof(";")));  
   　　}     
   }
