Comparing C# Int Arrays

Can you use generics? They are a little easier to deal with than arrays:

private void simpleButton2_Click(object sender, EventArgs e)
    {
      List<int> free = new List<int>();
      List<int> used = new List<int>();
      free.AddRange(new int[] { 1, 2, 3, 4, 5, 6 });
      used.AddRange(new int[] { 2, 3 });

      int nextNumber = GetNextFreeNumber(free, used);
      System.Diagnostics.Debugger.Break();
    }
    private int GetNextFreeNumber(List<int> free, List<int> used)
    {
      foreach (int i in free)
      {
        if (used.Contains(i))
          continue;
        else
        {
          used.Add(i);
          return i;
        }
      }
      throw new Exception("out of free number");
    }

I haven't used generics before. The arrays are already built and filled. Is there an easy way to move the aray data to the generics? There are about 300 elements per array.

Yes:

private void simpleButton2_Click(object sender, EventArgs e)
    {
      int[] numbers = new int[] { 1, 2, 3, 4, 5, 6, 7 };
      List<int> lst = new List<int>();
      lst.AddRange(numbers); //adds the array to the generic list

That Got It! Thank you so much! Plus I learned about Generics for the first time. Will study up more on that.

Here's the code I used in the end for those interested:

List<int> free = new List<int>();
List<int> used = new List<int>();
free.AddRange(FreeNumbers); //adds the array to the generic list
used.AddRange(UsedNumbers); //adds the array to the generic list

foreach (int i in free)
	{
	if (used.Contains(i))
	continue;
	else
		{
		Response.Write("<hr>");
		Response.Write(i);					
		Response.Write(" is the next available number<hr>");		
		break;
		}
	}

Now one more question...why didn't I join Daniweb sooner? :-)

Thanks again
