asp.net登录不了
在adminsys文件夹里面，有个Default.aspx文件，是登录入口，输入用户名跟密码老是提示“用户名密码错误，登录失败”不知道什么问题，查看了数据库里面Admin表的用户名和密码，发现我输入的用户名跟密码都是没错的，请高手帮忙啊！(1)/adminsys/Default.aspx代码如下：

--------------------编程问答-------------------- string[] userInfo = admin.login(uname, pwd);
admin.login返回的是什么？
if (userInfo[2].Equals(pwd))
这个判断是正确的吗？

你登陆方法加密了账号和密码，在数据库里的数据没有加密。所以虽然你输入的和数据库的一样，但经过加密后就不一样了。所以就会登录失败。
添加方法和登陆方法都要将密码加密。这样才能保持一致。
