//foreach语句示例
using System;
class MainClass 
{
   public static void Main() 
   {
      int odd = 0, even = 0;
      int[] arr = new int [] {0,1,2,5,7,8,11};

      foreach (int i in arr) 
      {
         if (i%2 == 0)  
            even++;      
         else 
            odd++;         
      }

      Console.WriteLine("发现 {0} 个奇数和 {1} 个偶数。", odd, even) ;
   }
}
