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);
