"plz tell me" is not really a subject, is it? It is more of an action.
In a string, there are many ways to move to the next line. There are the VB6 constants VbCrLf, VbCr, vbLf and VbNewLine.
Net has some specific ways to do this that re new to .NET, but I use the VB6 Consts, because I am used to them.
You could embed the code for a carriage-return/Line-Feed combination directly (0x0d, 0x0a [13, 10]), but that would not be a good idea. (Bad coding habit.)
