ArrayList[]=new ArrayList[]?

Question

ArrayList[] adUrls;
private void GetAdUrl(WebBrowser[] webs)
        {
            adUrls = new ArrayList[webs.Length];
 
            for (int i = 0; i < webs.Length;i++ )
            {
                adUrls[i] = new ArrayList();
                Regex r = new Regex(Reg(webs[i].Url.Host), RegexOptions.IgnoreCase | RegexOptions.Compiled);
                Match m = r.Match(webs[i].DocumentText.ToLower());
                while (m.Success)
                {                    if (!adUrls[i].Contains((webs[i].Url.ToString().Replace(GetSurf(webs[i].Url.Host), "")) + @"view.php?" + m.Value))
                    {
                        adUrl[i]s.Add((webs[i].Url.ToString().Replace(GetSurf(webs[i].Url.Host), "")) + @"view.php?" + m.Value);                    }
                    else
                    {                    }
                    m = m.NextMatch();
                }
                foreach (string str in adUrl[i])
                {
                    listBox1.Items.Add(str);
                }
            }
        }
listBox1中什么都没有。ArrayList[]可不可以这么用啊！

ArrayList adUrls;
private void GetAdUrl(WebBrowser[] webs)
        {
            adUrls = new ArrayList(webs.Length);            for (int i = 0; i < webs.Length;i++ )
            {
                adUrls[i] = new ArrayList();
                Regex r = new Regex(Reg(webs[i].Url.Host), RegexOptions.IgnoreCase | RegexOptions.Compiled);
                Match m = r.Match(webs[i].DocumentText.ToLower());
                while (m.Success)
                {                    if (!adUrls[i].Contains((webs[i].Url.ToString().Replace(GetSurf(webs[i].Url.Host), "")) + @"view.php?" + m.Value))
                    {
                        adUrls.Add((webs[i].Url.ToString().Replace(GetSurf(webs[i].Url.Host), "")) + @"view.php?" + m.Value);                    }
                    else
                    {                    }
                    m = m.NextMatch();
                }
                foreach (string str in adUrl)
                {
                    listBox1.Items.Add(str);
                }
            }
        }

Answer 2

当然可以这么用的.你设断点看看
                    if (!adUrls[i].Contains((webs[i].Url.ToString().Replace(GetSurf(webs[i].Url.Host), "")) + @"view.php?" + m.Value)) 
                    { 
                        adUrl[i]s.Add((webs[i].Url.ToString().Replace(GetSurf(webs[i].Url.Host), "")) + @"view.php?" + m.Value);                     } 
                    else 
                    {                     } 
这里的if条件是否成立过.即adUrl[i]s.Add 是否添加进了内容.

Answer 3

  foreach (string str in adUrl[i]) 
                { 
                    listBox1.Items.Add(str); 
                } 
改为
  foreach (object obj in adUrl[i]) 
                { 
                         string str=(string)obj;
                    listBox1.Items.Add(str); 
                } 这样，你再试试

Answer 4

if条件是不加入相同的元素，不使用ArrayList[] adUrls时成立
