If you're running ruby without any arguments and then typing your script
in directly, you need to send the end of file character at the end of
the script.  Since you mention C#, you're probably running on Windows
with the cmd console.  In that case, type Ctrl-Z and then Enter.  If
you're at a Unix terminal or running under Cygwin, type Ctrl-D.

A better way to try things out is to put them into a file and then run
the file using ruby.  This will allow you to easily go back and make
changes without having to retype everything.

An even better way to try simple stuff out like this is to use irb.  The
irb program gives you a prompt that takes ruby code line-by-line and
executes it, giving you a result after each line or complete statement.
 It's very handy.
