C#中的简单问题

问题描述：

大家好，

谁能告诉我下面是什么样的东西:

Hi all,

can anyone told me that Kind of sort is it below:

string[] data = listbox1.Items.Cast<string>().ToArray();

          ArrayList arr = new ArrayList();

          foreach (string s in data)
              if (!s.StartsWith(" "))
                   arr.Add(s);

          arr.Sort();
          listBox2.DataSource = arr;

我介意它是否可以调用快速排序或.... ??

thnx

I mind if it can call quick sort or....??

thnx

答

如果您问ArrayList.Sort使用哪种排序，它将使用Quicksort.
请参阅此链接中的备注"部分: http://msdn.microsoft.com/en-us/library/8k6e334t.aspx [ ^ ]

If you are asking what kind of sort is used by ArrayList.Sort, it uses Quicksort.
See the Remarks section in this link: http://msdn.microsoft.com/en-us/library/8k6e334t.aspx[^]

如解决方案1所述，mscorblib.dll的System.Array类的Sort方法内部使用了QuickSort，如下所示，

As mentioned in the solution 1, Sort method of the System.Array class of mscorblib.dll used QuickSort internally as showing below,

IL_0128:  call   instance void System.Array/SorterGenericArray::QuickSort(int32,
                                                                                int32)

希望对您有所帮助:)

Hope it helps :)
