Thanks all of you.

Did you put the following at the top of your page?:

<%@ Import Namespace="System.IO" %>

 

This import is used to let you manipulate files(like save information to a text file).

Thank you, but when import that segment, this error was still issued

And i think that it isn't main reason.

 

let's help me.

Thanks

Can you tell me your file structure?

 

Have you created the virtual directory for testing?

 

 

Thanks your helps

I already found out the reason, because i configed by tool not correct so now it's ok.

But i have encountered the new problem with language, i used the new xml file and config culture type is server, culture is "vn-VN", but it didn't effect. Some title, button has still valued [["Add Contacts"]] or [["Search"]

Can you help me. Thanks.
