我怎样才能把中文转换成unicode, 我需要user input chinese to a Textbox, 然后把这个Textbox.Text 转换成unicode ,然后存到database, 怎样做啊？

浏览器好像会自动替你做的~

谢谢你， 不过用户输入以后，是存在一个variable 里面呀， system 不能帮我convert 阿， 我想把这个variable 里面的chinese char save to database

当你浏览一个page 的时候

如果你输入的语言 跟 page 的 encoding 不是相同的时候， 比如 你的page encoding 是 iso-xxxx- 你的输入是 GBK or GB2312
浏览器 就会自动 把你的 chinese 转成 unicode 然后提交给 服务器

跟是不是 ASP 没有任何关系

i am a web developer,developing asp.net backend , i am not a frontend user.
i know chinese char can be converted to unicode. i am a seeking for a way that convert any char to unicode, which actually be done auto. i need a 1-line command. any one know asp.net well can help me with this?

seems i have not done this before.

sorry.

you can set this in your web.config file

<globalization requestEncoding="utf-8" responseEncoding="utf-8" /> (or you can set decode/encode for that specific page).

this will convert all into utf characters.

to store this in the database, i suggest you use nvarchar instead of varchar data type.

hope this is help for you!
