In C#-WinForms I use a OpenFileDialog. I want to get all files/filenames in a selected folder, without pressing the ok button of the OpenFileDialog.

Is there a good way to achieve this?

It's strange to get the (not by the user confirmed) selected filename. Probably not.

Hi Paul, welcome to so! Can you please consider editing your question so that it is easier for people to answer, perhaps providing some code you have already tried and is not working for example. At the moment I don't think your question is clear enough to answer.

What "code example" do you expect in this situation? Code reading the files after they have been selected? The OP is asking how to read the filenames before the users hits the "ok" button.

It is a dialog, it won't complete and won't tell you what was selected until you click OK. Necessarily so, a selected file can be unselected again. So what you want is not in the cards. It has a FileOk event that fires early when the user selects a file, it is meant to prevent selection. Whether that is what you want is not at all clear from the question.

if i understood your question in the right way, you want to get the Filenames out of your selected folder. To archive that, you could use a FolderBrowserDialog.

FolderBrowserDialog folderBrowser = new FolderBrowserDialog();
if(folderBrowser.ShowDialog() == DialogResult.OK)

 var path = folderBrowser.SelectedPath;
 System.Windows.IO.DirectoryInfo info = new System.Windows.IO.DirectoryInfo(path);
 foreach(var file in info.GetFiles())
 
 //do what you want with your files.
 //example
 listbox1.Items.Add(file.Name);

If you got some further question, feel free to ask.

-- EDIT --

Ok now i understood what you mean.

You want to get the files out of a folder when clicking on it.
Maybe build your own dialog (simple new window). With a treeview on it. And if you click on a treeviewitem, on ther other side it displays you the files and subfolder.

The easiest way would be to create a new dialog your self as i mentoined in my edit. Just create a new Window with a treeview oder maybe two treeviews. One on the left the other one on the right, same like windows explorer layout.
