Hurry up, aspnet C # traverse the files in the folder and bind the file name to the GridView. How can I write the download path to download these files?

Just output the files on the server to the client as a stream.

Aspnet (c #) traverses a folder with TreeView. How can I click a node to open the file?

Now that you have traversed the folder
Add it cyclically in the selectedChanged event
System. Diagnostics. Process. Start ("f: \ a.txt ");
Next, just traverse it again and try again. Wish you success.
