blocks|key|2634883|text|这是我最近研究的一个有趣的话题。正如你所知道的，你可以通过COM访问BITS，但这里有几个项目可以让它变得更容易：|type|unstyled|depth|inlineStyleRanges|entityRanges|data|2634884|SharpBITS.NET|offset|length|2634885|Forms+Designer+Friendly+Background+Intelligent+Transfer+Service+(BITS)+wrapper|2634886|这个article+on+MSDN可能比你想知道的要多一点。|2634887|我对CodeProject链接中的代码进行了实验，它似乎工作得相当好。CodePlex项目看起来真的很不错，但我还没有尝试过。|2634888|entityMap|0|LINK|mutability|MUTABLE|url|http://www.codeplex.com/sharpbits|1|http://www.codeproject.com/KB/cs/Managed_BITS.aspx|2|http://msdn.microsoft.com/en-us/magazine/cc188766.aspx^0|0|0|D|0|0|0|26|1|0|2|F|2|0|0^^$0|@$1|2|3|4|5|6|7|X|8|@]|9|@]|A|$]]|$1|B|3|C|5|6|7|Y|8|@]|9|@$D|Z|E|10|1|11]]|A|$]]|$1|F|3|G|5|6|7|12|8|@]|9|@$D|13|E|14|1|15]]|A|$]]|$1|H|3|I|5|6|7|16|8|@]|9|@$D|17|E|18|1|19]]|A|$]]|$1|J|3|K|5|6|7|1A|8|@]|9|@]|A|$]]|$1|L|3|-4|5|6|7|1B|8|@]|9|@]|A|$]]]|M|$N|$5|O|P|Q|A|$R|S]]|T|$5|O|P|Q|A|$R|U]]|V|$5|O|P|Q|A|$R|W]]]]

This is an interesting topic I investigated fairly recently. As you know you can access BITS via COM, but here are a couple projects to make it easier:

<a href="http://www.codeplex.com/sharpbits" rel="nofollow noreferrer">SharpBITS.NET</a> 
<a href="http://www.codeproject.com/KB/cs/Managed_BITS.aspx" rel="nofollow noreferrer">Forms Designer Friendly Background Intelligent Transfer Service (BITS) wrapper</a>

This <a href="http://msdn.microsoft.com/en-us/magazine/cc188766.aspx" rel="nofollow noreferrer">article on MSDN</a> might be a bit more than you want to know. 

I experimented with the code in the CodeProject link and it seemed to work reasonably well. The CodePlex project looks really good but I haven't tried it.

blocks|key|2634928|text|好吧，如果Web服务器允许列出有问题的目录中的文件，那么您就可以使用了。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|2634929|不幸的是，web服务器如何返回列表并没有标准。它通常是HTML格式的，但HTML在多个web服务器上的格式并不总是相同。|2634930|如果你想总是从同一个web服务器上的同一个目录下载文件，只需在你的web浏览器中的目录中执行一个"view+source“。然后尝试编写一个小的正则表达式，它将从HTML源文件中获取每个文件名。|2634931|然后，您可以创建一个WebClient，请求目录URL，解析响应以使用正则表达式获取文件名，然后使用BITS客户端处理这些文件|2634932|希望这能有所帮助|2634933|entityMap^0|0|0|0|0|0^^$0|@$1|2|3|4|5|6|7|L|8|@]|9|@]|A|$]]|$1|B|3|C|5|6|7|M|8|@]|9|@]|A|$]]|$1|D|3|E|5|6|7|N|8|@]|9|@]|A|$]]|$1|F|3|G|5|6|7|O|8|@]|9|@]|A|$]]|$1|H|3|I|5|6|7|P|8|@]|9|@]|A|$]]|$1|J|3|-4|5|6|7|Q|8|@]|9|@]|A|$]]]|K|$]]

Well, if the Web Server allows to list the files the directory in question, you're good to go.

Unfortunately, there's no standard on how the web server should return you the list. It is often in HTML, but the HTML is not always formatted the same across multiple web servers.

If you want to download files always from the same directory on the same web server, just do a "view source" while being in the directory in your web browser. Then try to write a small regular expression that will grab every file names from the HTML source.

You can then create a WebClient, request the directory URL, parse the response to get the file names with your regular expression, then process the files with your BITS client

Hope this helps

I write some code that can get all path infos, including file and dir, from the IIS site which allow list directory. You can customize the regex to match your need (Or change to use html parser). Further you can add some code yourself to get more detailed info, like file size or create time.

you can get all path infos in 2 lines:

<pre><code>List&lt;PathInfo&gt; pathInfos = new List&lt;PathInfo&gt;();
HttpHelper.GetAllFilePathAndSubDirectory("http://localhost:33333/", pathInfos);
</code></pre>

The helper code:

<pre><code>public static class HttpHelper
{
 public static string ReadHtmlContentFromUrl(string url)
 {
 string html = string.Empty;
 HttpWebRequest request = (HttpWebRequest)WebRequest.Create(url);

 using (HttpWebResponse response = (HttpWebResponse)request.GetResponse())
 using (Stream stream = response.GetResponseStream())
 using (StreamReader reader = new StreamReader(stream))
 {
 html = reader.ReadToEnd();
 }
 //Console.WriteLine(html);
 return html;
 }

 public static void GetAllFilePathAndSubDirectory(string baseUrl, List&lt;PathInfo&gt; pathInfos)
 {
 Uri baseUri = new Uri( baseUrl.TrimEnd('/') );
 string rootUrl = baseUri.GetLeftPart(UriPartial.Authority);


 Regex regexFile = new Regex("[0-9] &lt;a href=\"(http:|https:)?(?&lt;file&gt;.*?)\"", RegexOptions.IgnoreCase);
 Regex regexDir = new Regex("dir.*?&lt;a href=\"(http:|https:)?(?&lt;dir&gt;.*?)\"", RegexOptions.IgnoreCase);

 string html = ReadHtmlContentFromUrl(baseUrl);
 //Files
 MatchCollection matchesFile = regexFile.Matches(html);
 if (matchesFile.Count != 0)
 foreach (Match match in matchesFile)
 if (match.Success)
 pathInfos.Add(
 new PathInfo( rootUrl + match.Groups["file"], false));
 //Dir
 MatchCollection matchesDir = regexDir.Matches(html);
 if (matchesDir.Count != 0)
 foreach (Match match in matchesDir)
 if (match.Success)
 {
 var dirInfo = new PathInfo(rootUrl + match.Groups["dir"], true);
 GetAllFilePathAndSubDirectory(dirInfo.AbsoluteUrlStr, dirInfo.Childs);
 pathInfos.Add(dirInfo);
 } 

 }


 public static void PrintAllPathInfo(List&lt;PathInfo&gt; pathInfos)
 {
 pathInfos.ForEach(f =&gt;
 {
 Console.WriteLine(f.AbsoluteUrlStr);
 PrintAllPathInfo(f.Childs);
 });
 }

}



public class PathInfo
{
 public PathInfo(string absoluteUri, bool isDir)
 {
 AbsoluteUrl = new Uri(absoluteUri);
 IsDir = isDir;
 Childs = new List&lt;PathInfo&gt;();
 }

 public Uri AbsoluteUrl { get; set; }

 public string AbsoluteUrlStr
 {
 get { return AbsoluteUrl.ToString(); }
 }

 public string RootUrl
 {
 get { return AbsoluteUrl.GetLeftPart(UriPartial.Authority); }
 }

 public string RelativeUrl
 {
 get { return AbsoluteUrl.PathAndQuery; }
 }

 public string Query
 {
 get { return AbsoluteUrl.Query; }
 }

 public bool IsDir { get; set; }
 public List&lt;PathInfo&gt; Childs { get; set; }


 public override string ToString()
 {
 return String.Format("{0} IsDir {1} ChildCount {2} AbsUrl {3}", RelativeUrl, IsDir, Childs.Count, AbsoluteUrlStr);
 }
}

How do I get a list of files from a web directory? If I access the web directory URL the internet browser list all the files in that directory. Now I just want to get that list in C# and download them in BITS (Background Intelligent Transfer Service) .

如何从web目录获取文件列表？如果我访问web目录URL，internet浏览器会列出该目录中的所有文件。现在我只想以C#格式获取该列表，并以BITS (后台智能传输服务)格式下载它们。
