If i want to fill an array with numbers, but im not sure what the size is until i run the program how do i make an array adjustable?  I assume you would need to put it in some kind of for loop,

If i read in a list of numbers i would usually do this

static int[] array = new int[10];

for(int i=0; i<split.Length; i++)
{
       array[i] = int.Parse(split[i]);
}

ok so thats going to put them in the array.  Now when i go to sort that array using a bubble sort if the numbers which were read in didn't fill the whole array i get "0" when i sort it and it messes the sort up.

Hi, as Raymun suggested, you can use a dynamic collection such as an ArrayList:

ArrayList array = new ArrayList();

for (int i = 0; i < split.length; i++)
      array.Add(split[i]);

//looping through the ArrayList
int currentInt;
for (int j = 0; j < array.Count; j++)
     currentInt = int.Parse(array[j].ToString());
