前台获取Cookie的值

Question

后台加入Cookie 
HttpCookie PicCookie = new HttpCookie("PicCookies");PicCookie.Values.Add("id_1_1","N-123456");
PicCookie.Values.Add("title_1_1", "T-123456");前台网页中读取
<%=Request.Cookies["PicCookies"].Values["title_1_1"] %>
<%=Request.Cookies["PicCookies"].Values["id_1_1"] %>一运行前台就（未将对象引用设置到对象的实例。）

Answer 1

忘了写这个了Response.AppendCookie(PicCookie);

Answer 2

HttpCookie PicCookie = new HttpCookie("PicCookies"); PicCookie.Values.Add("id_1_1","N-123456"); 
PicCookie.Values.Add("title_1_1", "T-123456"); Response.Cookies.Add(PicCookie);把红色部分加上，你都没添加到response，怎么可能在前台能拿到呢？

Answer 3

再者 送你一段js取cookie的代码//读取cookie
       function readCookie(name)
       {
           var start = document.cookie.indexOf( name + "=" ); 
           var len = start + name.length + 1;     
           if ( ( !start ) && ( name != document.cookie.substring( 0, name.length ) ) ) 
           {         
                return null;     
           }     
           if ( start == -1 )
                 return null;     
          var end = document.cookie.indexOf( ';', len );     
          if ( end == -1 ) 
            end = document.cookie.length;
          return decodeURI(document.cookie.substring(len,end)); 
       }
