C#은 동적으로 어떻게 구현할지 모르겠네요

 public static void printSumAndAvg() throws NumberFormatException, IOException {
 double sum = 0; //합계
 double avg = 0d; //평균
 BufferedReader br = new BufferedReader(new InputStreamReader(System.in));
 int intCnt = Integer.parseInt(br.readLine());
 List<Integer> intList = new ArrayList<Integer>();
 for(int i = 0; i < intCnt; i++) {
 intList.add(Integer.parseInt(br.readLine()));
 }
 br.close();
 Iterator<Integer> iter = intList.iterator();
 while(iter.hasNext()) {
 sum += iter.next();
 }
 avg = sum / intCnt;
 System.out.printf("정수의 합 : %f, 평균 : %.2f\n", sum, avg);
 }

python3 입니다

n = int(input("정수의 개수 입력: "))
n_sum = 0
for i in range(n):
 n_input = int(input("정수 입력: "))
 n_sum += n_input
n_avg = n_sum / n
print(n_sum)
print(n_avg)
del n, n_sum, n_avg
