在.net 1.x 中, 实现多语言功能, by shawl.qiu

说明:
这两天看了N种实现多语言的方案, 但都N麻烦, 动不动就有些功能不支持:(
像类 System.Resources.ResXResouceWriter 和命名空间 Microsoft.JScript... 在我的.NET Framework 居然找不到...:(

有鉴于此, 虽然功能实现了, 但还是总结总结, 希望对其他人有帮助...

主要是使用 xml 形式的 DataSet 实现...
考虑中英文目录应该是两份站点文件, 所以用 web.config 设置各站点的主要功能... 比如默认语言..Cookie 名等...

嗯, 这个功能现在被我弄得还是挺简单的, 就不多说明了...

目录
1. web.config
2. default.aspx
3. English.xml
4. Chinese.xml
