C#使用foreach语句搜索数组元素的方法

using System;
public class Search {
 public static void Main() {
  int[] nums = new int[10];
  int val;
  bool found = false;
  // give nums some values
  for(int i = 0; i < 10; i++) 
   nums[i] = i;
  val = 5;
  // 通过foreach语句在nums数组中查找指定元素
  foreach(int x in nums) {
   if(x == val) {
    found = true;
    break;
   }
  }
  if(found) 
   Console.WriteLine("Value found!");
 }
}
