Question

我在WinXP上运行此问题（在Windows 8和Windows 7运行没有问题）并且没有看到问题所在。

我应该登录管理页面，但仍然要求我输入密码。（它看到了用户名）。所以我假设是饼干。

我使用.net framework 4

using System.Collections.Generic;

我认为在Xp上的默认浏览器中未启用Cookie

检查Cookie是否已启用或未在浏览器网址中粘贴以下代码并按Enter键。

javascript:alert(navigator.cookieEnabled);

HttpWebRequest Cookies不适用于WinXP
