C# foreach语句中使用break暂停遍历

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); 
  } 
}
