Here's my problem:
I've got a form with a combobox. I want to add the contents to an array each time I click on button1, and the array is in the Global.cs file 
using System;
using System.Collections;
using System.IO;
namespace WindowsApplication1
{
	public class Globals
	{
		private Globals()
		{
			
		}
		public static ArrayList getList()
		{
			ArrayList arr = new ArrayList();
			string cmbval;		// value from combo
			foreach(string cmbval)
			{
				arr.AddRange(cmbval);
			}
			return arr;
		}
	}
}
and am writing this behind the button1:
	string cmbval = cboChoose.Text.ToString();
	Globals.getList();
Please help.
