各位亲们，菜鸟求帮助，我们头儿给了我两个做好的web网页，他让我做主页里面包括用户登录，添加用户等东西，我现在不知道从哪里开始

看来你门都没入，怎么就开始上班了呢？准备好有书看书，没书就百度、谷歌狂搜吧，这个不难的，花十几个小时也就搞定了。
新建页面->放置控件->获取数据->判断逻辑->根据判断结果动作，就这么简单，呵呵！

看来找工作真容易.

唉我现在连css都不太会啊，前一阵做有关winforn的啦，这种web的布局啊什么母版的啊让我乱糟糟的

我遇到困难啦！！！我在用vs 用母版页做另一个web的时后，往添加的label控件里输入内容的时候，内容显示出来是倒着的，这是怎么回事？

不小心把RightToLeft设置了吧？

我又来了。。。请问怎么把添加用户的密码写到数据库的时候是加密的呢？

如果加密了是不是就是数据库里看不到真正的密码啊
那登录的时候怎么办

                decryptStream, decryptTransform, System.Security.Cryptography.CryptoStreamMode.Write);
            decryptor.Write(encryptBytes, 0, encryptBytes.Length);
            decryptor.Close();
            var decryptBytes = decryptStream.ToArray();
            var decryptedString = Encoding.UTF8.GetString(decryptBytes, 0, decryptBytes.Length);
            return decryptedString;
        }
    }
}

字符串加密，登录时加密输入的密码看是否与数据库的数据相符就可以了。

那样不是asp了吗
