Oh i thought the using statements where the csharp equivalents of the #include statements i used in C++ Now i realize that adding references is the real deal... Using statements are just for our convenience Pretty informative link by the way Thanks....

Check the following link for a brief tutorial: http://www.brainbell.com/tutors/C_Sharp/Namespaces_and_the_using_Directive.htm As for System and System.Text by writing using System; you will be able to use the classes defined in the System namespace. But System.Text is again a namespace so you need to import that separately through another using statement.
