C#中foreach语句使用break暂停遍历的方法

using System;
public class w3demo {
 public static void Main() {
  int sum = 0;
  int[] nums = new int[10];
  // give nums some values
  for(int i = 0; i < 10; i++) 
   nums[i] = i;
  // use foreach to display and sum the values
  foreach(int x in nums) {
   Console.WriteLine("Value is: " + x);
   sum += x;
   if(x == 4) break; // 当x=4时停止遍历
  }
  Console.WriteLine("Summation of first 5 elements:" + sum);
 }
}
