下面的代码演示了在C#中使用foreach时如何通过break语句暂停数据遍历

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); } }
