namespace ConsoleApplication1
{

  class Program
  {
      static void Main(string[] args)
      {

          ArrayList numbers = new ArrayList();
          numbers.Add(10);
          numbers.Add(22);
          numbers.Add(3);

          numbers.Add(5);
          numbers.Add(9);
          Console.WriteLine("The elements of the arraylist are:");
          foreach (int i in numbers)

          {
              Console.WriteLine(i);
          }
          Console.WriteLine("The element 22 contain in the ararylist is:" + numbers.Contains(22));

          Console.WriteLine("The element 12 contain in the ararylist is:" + numbers.Contains(12));
          Console.WriteLine("The element 10 contain in the ararylist is:" + numbers.Contains(10));
          Console.WriteLine("The element 9 contain in the ararylist is:" + numbers.Contains(9));
          Console.WriteLine("The element 40 contain in the ararylist is:" + numbers.Contains(40));

          Console.WriteLine("The element 5 contain in the ararylist is:" + numbers.Contains(5));
      }
  }
}

C# ArrayList的Contain方法检查特定元素是否存在于ArrayList中，如果元素存在，则返回true，否则返回false。
