Environment NewLine should be used as Dan Rigby said but there is one problem with the String Empty  It will remain always empty no matter if it is read before or after it reads  I had a problem in my project yesterday with that  I removed it and it worked the way it was supposed to  It s better to declare the variable and then call it when it s needed  String Empty will always keep it empty unless the variable needs to be initialized which only then should you use String Empty  Thought I would throw this tid-bit out for everyone as I ve experienced it
