A VERY basic random quote generator in C#, windows Windows Forms and reflection

Form1.cs

/*
 * Project Name:            Random Quote Generator
 * Solution Name:           Random Quote Generator
 * Original creation date:  18/06/2006
 * Edit date:               18/01/2013
 * Programmer name:         Jamie Taylor (aka "GaProgMan")
 * File name:               Form1.cs
 * 
 * Purpose of the project:
 *
 *	This is a peice of hobby code written after I had the
 *	idea of creating a random quote generator.
 *		The basic idea came to me after watching way
 *	too many TV shows and films and wanting to impress my
 *	friends with random quotes taken from those shows.
 *		Originally designed to load a text file called
 *	"Quotes.txt" into memory, then randomly picking out a
 *	line (all individual quotes are stored on a single line
 *	of the file) into "lines" and displaying it in the text
 *	box "QuoteLabel".
 *		When the user presses the button labelled
 *	"Generate", the	program then chooses another random
 *	quote and displays it in the text box.
