asp.net是有可能从一个静态类读取cookie的值？ [英] asp.net is it possible to read the value of a cookie from a static class?

问题描述

我有一个静态属性的值存储在用户访问该网站的cookie最后一次的currentUser类。我希望能够从这个类读取cookie的值。可能吗？它看起来像Request.Cookies时只在网页中使用。什么，我试图做一个简化的版本是：

 类的currentUser
{
公共静态字符串MyField的
            {                得到
                {
                    返回Request.Cookies时[MyField的];
                }            }}
 

这是行不通的。我得到这个错误信息：名字请求没有在目前的情况下存在

解决方案

 使用的System.Web;
...
返回HttpContext.Current.Request.Cookies [MyField的];
 

I have a CurrentUser class with a static property whose value was stored in a cookie last time the user visited the website. I would like to be able to read the value of the cookie from this class. Is it possible? It looks like Request.Cookies is only available in web pages. A simplified version of what I'm trying to do is:

class CurrentUser
{
public static string MyField
            {

                get
                {
                    return Request.Cookies["MyField"];
                }

            }

}

This doesn't work. I get this error message: "the name 'Request' does not exist in the current context'.

解决方案

using System.Web;
...
return HttpContext.Current.Request.Cookies["MyField"];
