C#集合的性能与stopwatch的用法

用哪种集合来存取对象更快些？经过实验安全的更快些。

假定有一个对象Order

  List<Order> newSafeList = new List<Order>();//此种性能更好些
  ArrayList newUnsafeList = new ArrayList();

 测试代码：

   stopWatch.Start();
   for (int i = 1; i < 100000; i++)
   {
    Order newOrder = new Order(i, DateTime.Now, i + 100);

    newSafeList.Add(newOrder);
   }
   stopWatch.Stop();
   loadSafeListMs = stopWatch.ElapsedMilliseconds;
   stopWatch.Reset();

   stopWatch.Start();
   for (int i = 1; i < 100000; i++)
   {
    Order newOrder = new Order(i, DateTime.Now, i + 100);

    newUnsafeList.Add(newOrder);
   }
   stopWatch.Stop();
   loadUnsafeMs = stopWatch.ElapsedMilliseconds;
   stopWatch.Reset();

心得：

System.Diagnostics 下的Stopwatch能准确记录是去时间。

用法：

stopWatch.Start();

stopWatch.Stop();

stopWatch.Reset();
