I succeeded in developing C# code for drag files from windows explorer to listBox.
// Drag and Drop Files to Listbox
private void listBox1_DragEnter(obje
if fileName
is a directory you can create a DirectoryInfo
object and loop through all files (and subdirs)
you can have a look at this code:

(you dont need to use a DirectoryInfo
object, you can also use the static methods from the Directory
class
Your code for DragEnter
still applies for folders.
In the DragDrop
event, you retrieve filepaths and folder paths in the same way. If you drag combinations of files and folders, they will all show up in your files
array. You just need to determine if the paths are folders or not.
The following code will retrieve all the paths of all files from the root of all folders dropped, and the paths of all files dropped.
private void listBox1_DragDrop(object sender, DragEventArgs e)
{
List<string> filepaths = new List<string>();
foreach (var s in (string[])e.Data.GetData(DataFormats.FileDrop, false))
{
if (Directory.Exists(s))
{
//Add files from folder
filepaths.AddRange(Directory.GetFiles(s));
}
else
{
//Add filepath
filepaths.Add(s);
}
}
}
Note that only the files in the root of the folders dropped will be collected. If you need to get all files in the folder tree, you'll need to do a bit of recursion to collect them all.
