C＃-从远程目录获取文件名（不带锚）

Question

I have been trying to get from our localhost/remote directory listing of all images on that folder.

What I so far tried follows (based on others SO's questions, but changed a bit to include these on my arr', but still using a WebRequest.):

Regex regex = new Regex(GetDirectoryListingRegexForUrl(url));
var arr = regex.Matches(photosName).Cast<Match>().Select(m => m.Value).ToArray();

public static string GetDirectoryListingRegexForUrl(string url)
{
    if (url.Equals("http://localhost:MyPort/MyNewbieProject/images/"))
    {
        return "<a href=\".*\">(?<name>.*)</a>";
    }
    throw new EverythingExplodedException();
}

So, as a result from that, I get something like:

"<a href=\"All-Your-Base-00.jpg\"> All-Your-Base-00.jpg</a>"

I wanted to get just the "All-Your-Base-00.jpg", so I could download it into my App and use it to fill my Image's.

How should I proceed? Should I manually trim this string, or there is a better way to do so?

You want to get the captured group from the returned match. That is, you have:

var arr = regex.Matches(photosName).Cast<Match>().Select(m => m.Value).ToArray();

First, change that to:

var arr = regex.Matches(photosName).Cast<Match>();

You then want to go through each match:

foreach (Match m in arr)
{
    var name = m.Groups["name"].Value;
    // name now contains the captured group
}
