if (Position < Colors.Length - 1)

{

Position++;
return true;

}

else

return false;

}

public void Reset() // Reset
{
Position = -1;
}

public ColorEnumerator(string[] theColors) // Constructor

{

Colors = new string[theColors.Length];
for (int i = 0; i < theColors.Length; i++)
Colors[i] = theColors[i];

}

}
