there are two options to do it...

use google transation to automatically convert web site content while displaying...

but since u dont have control over that translation (and if u require that) u can go for globalization feature of asp.net

http://www.codeproject.com/KB/aspnet/localizationByVivekTakur.aspx

http://quickstarts.asp.net/QuickStartv20/aspnet/doc/localization/localization.aspx#simpleexample

or simple google search on globalization/locallization would give u plenty of resources...

hope this helps...
