Question regarding multi-language Web

Question

In the html page I have the images for different languages in separate subfolders (ex. “images\En\my.gif” ) In the C# code behind I have a variable indicating the selected language, ( ex. string languageCode=”En”) Is it possible to replace the “En” part of folder string with the languageCode, something like: “images\”+languageCode+”\my.gif”? What would the proper procedure and syntax be?
