Directory.GetFiles（）返回完整路径

Question

I want to return the files that are images, inside a particular directory. I want to create the image path like this

  string[] ImageNames = Directory.GetFiles(path);


        string tds="";
        for (int i = 0; i < ImageNames.Length; i++)
        {
          tds += "<tr> <td> <img href=/Articles/ArticleImageStore/'" + ImageNames[i] + "' width='64' height='64'></img></tr> </td>";
        }

but it returns the physical path of the file on the disk. How should I do this??

Answer 1

You can use Path.GetFileName :

string[] ImageNames = Directory.GetFiles(path)
                                    .Select(p => Path.GetFileName(p)).ToArray();

This will produce a list with only the names of the files.

Answer 2

Rather than using the Directory class I would use DirectoryInfo then you can do this;

 string[] fNames = new DirectoryInfo(dirPath).GetFiles("*.png").Select(x => x.FileName).ToArray();

The DirectoryInfo version of GetFiles returns FileInfo objects rather than the file paths as strings so you can do a lot more the with the results. I happen to have a select which sort of nullifies that by just projecting a the FileName for each FileInfo instance returned by GetFiles but if you needed to do more with the files you could remove that then loop over the FileInfo objects.

Also, I'm using an overload that has a pattern which will make it easy to ignore your non image files.
