如何在不包含目录路径的情况下返回目录文件/文件夹？

Question

I am trying to extract a list of files within a folder and am currently using:

 string[] files = Directory.GetFiles(txtbxNewFolder.Text);

But that returns things like "C:\\Users\\Dahlia\\Desktop\\New Folder\\jerry.txt". Is there a way to return only "jerry.txt", or do I need to do some sort of split on the array strings?

I am also trying to return a list of folders within a directory and am currently using:

string[] folders = Directory.GetDirectories(txtbxOldFolder.Text);

But that returns things like "C:\\Users\\Dahlia\\Desktop\\New Folder\\folder1". Is there a way to return only "folder1", or do I need to do some sort of split on the array strings?

Answer 1

Using LINQ you can get a list of just the files:

Directory.GetFiles(txtbxNewFolder.Text).Select(f => Path.GetFileName(f));

Though rather than GetFiles I'd probably use:

Directory.EnumerateFiles(txtbxNewFolder.Text).Select(f => Path.GetFileName(f));

It isn't as simple to get the directory name, but this should work (untested):

Directory.GetDirectories(txtbxOldFolder.Text)
    .Select(d => new DirectoryInfo(d).Name);

Similarly, there is a:

Directory.EnumerateDirectories(txtbxOldFolder.Text)
    .Select(d => new DirectoryInfo(d).Name);

You could use Path.GetFileName and LINQ

eg:

string[] files = Directory.GetFiles(txtbxNewFolder.Text)
                          .Select(f => Path.GetFileName(s))
                          .ToArray();

Have a look at the FileInfo and DirectoryInfo classes.

You can do:

foreach (String file in files) {
    var fi = new FileInfo(file);
    Console.Out.WriteLine(fi.Name);
}

Similar for DirectoryInfo.
