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); }}
