I have an ArrayList, and I need to be able to click a button and then randomly pick out a string from that list and display it in a messagebox.

Create an instance of
Random class somewhere. Note that it's pretty important not to create a new instance each time you need a random number. You should reuse the old instance to achieve uniformity in the generated numbers. You can have a
static field somewhere (be careful about thread safety issues):
static Random rnd = new Random();
Random instance to give you a random number with the maximum of the number of items in the
int r = rnd.Next(list.Count);
Display the string:
