C# Keeping sentinel value out of my array -

this code works when enter 10 values. if enter less sentinel value added. i'd stop, being able manipulate array length don't many 0's left when entering less 10.

using system; using system.collections.generic; using system.linq; using system.text; using system.threading.tasks; using static system.console; namespace integerstatistics { class program {     static void main(string[] args)     {         int[] numbers = new int[10];         int arraycount, high, low, sum;         double avg;          arraycount = fillarray(numbers);           statistics(numbers, arraycount, out high, out low, out sum, out avg);          (int x = 0; x < numbers.length; ++x)             write("{0, 4}", numbers[x]);         writeline();         writeline("the array has {0} values", arraycount);         writeline("the highest value {0}", high);         writeline("the lowest value {0}", low);         writeline("the sum of array {0}", sum);         writeline("the average {0}", avg);      }      private static int fillarray(int[] numbers)     {          const int quit = 999;         string enternum;         int stop;         int count = 0;         int addnum = 0;         stop = numbers.length - 1;         while((addnum != quit) && (count <= stop))         {             write("enter number or 999 exit: ");             enternum = readline();             while (!int.tryparse(enternum, out numbers[count]))                 {                 writeline("error");                 write("enter number or 999 exit: ");                 enternum = readline();             }               numbers[count] = convert.toint32(enternum);             addnum = numbers[count];             ++count;            }         return count;       }      private static int statistics(int[] numbers, int arraycount, out int high, out int low, out int sum, out double avg)     {         high = numbers.max();         low = numbers.min();         sum = numbers.sum();         avg = numbers.average();           return arraycount;     }     } 

}

first, let's fix code, because simple: rather using numbers.length in main, use arraycount. have, , stop main showing zeros @ end.

i'd [...] manipulate array length

although .net provides way resize array, not should doing in general, because code becomes hard read.

a better solution problem return sized array fillarray. however, best solution switch using list<t>, allowed grow , shrink needed.
