Let me give an example of what is happening.

Array.Resize() returns another object - the original array continues to exist for as long as it is referenced

	public class AClass
	{
		public static string[] Tables = { "one", "two", "three" };

		public static void Main()
		{
			string[] tables = Tables;

			Array.Resize<string>(ref Tables, 10);

			Console.WriteLine("previous version contains {0} elements", tables.Length);  // 3
			Console.WriteLine("newer version contains {0} elements", Tables.Length);  //10
			Console.ReadLine();
		}

	}
