Visual Studio 2005 on Japanese

Does anyone know how I can express inputted japanese character-numbers, (１２３４５６７８９０) as normal integer values (1234567890)

if im writing an application for a japanese user and they enter on the form in a textbox "７", in the japanese font, how can i convert this as intger 7?

if i get the textbox.text value, it doesnt convert to an intger, even the char datatype doesnt like it.
