推荐答案
使用服务器文本框（System.Web.UI.WebControls.Textbox）。他们
自动做你想做的事。

Winform？有很多方法可以做到这一点。我正在创建一个类，其中包含
用户名并将其序列化到用户配置文件文件夹中的磁盘。
如果您需要代码，请给我发电子邮件

Winform? Lots of ways to do this. I am creating a class that holds the
username and serializing it to disk in the user profile folder.
email me if you want the code

如果它是Windows窗体（桌面）应用程序，您可以将其保存到
注册表中。 />
对于任何类型的应用程序，您都可以将信息保存到数据库表中。如果
执行机器的权限允许，您也可以将其保存为
文件系统，如XML或文本。对于基于浏览器的应用程序，您可以使用存储在用户计算机上的cookie
。
这是一种非常糟糕的安全措施填写一个
密码字段（你可能只需要在显示器上粘贴一个带有信息的便利贴
）。 *永远不要*这样做。但是，对于使用cookie的基于浏览器的应用程序
，自动登录（不显示登录表单）是
常见做法。如果你这样做，请确保你加密密码所以它不能被访问计算机的人简单地读取。我建议
反对这样做，因为访问的数据是敏感的。
你真的应该向你的应用程序的用户解释一些额外的
他们必须输入登录的键击才能更好地保证安全性。如果他们抱怨b $ b，告诉他们那么他们就不应该为安全而烦恼而且只有
让任何人都敞开心扉，因为那基本上就是他们'
想要。

If it''s a Windows Forms (desktop) application, you can save it to the
registry.
For any type of app, you can save the information to a database table. If
the permissions of the executing machine allow it, you can also save to the
filesystem as XML or text. For a browser-based app, you could use a cookie
stored on the user''s machine.
It is an extremely bad security practice to automatically populate a
password field (you might as well just stick a post-it note with the info on
the monitor). *NEVER* do this. However, in the case of a browser-based app
using a cookie, automatic login (without displaying the login form) is a
common practice. If you do this, be certain you encrypt the password so it
can''t be simply read by someone who gains access to the computer. I advise
against doing this where the data being accessed is sensitive.
You really should explain to the users of your app that the few extra
keystrokes they have to enter to login is far better for security. If they
complain, tell them then they shouldn''t bother with security at all and just
leave it wide open for anyone, since that''s essentially what they''re
wanting.
