File System

I am attempting to get a list of all files in a directory on the SD card.

Is this possible with current implementations? I was not able to find any function to do so.

Thanks

System.IO.Directory.GetFiles(string folderpath)

This isn’t working? I am just starting to work with the SDCard and programmed it up this way but haven’t given it a try yet.

Yeah, just tried this on a usb drive and it works as expected.

            var sd = StorageController.FromName(@"GHIElectronics.TinyCLR.NativeApis.STM32H7.SdCardStorageController\0");
            var drive = FileSystem.Mount(sd.Hdc);
            // Show a list of files on root directory
            var directory = new DirectoryInfo(drive.Name);
            var files = directory.GetFiles();
            foreach (var f in files)
            {
                Debug.WriteLine(f.Name);
            }
            FileSystem.Flush(sd.Hdc);
            Thread.Sleep(Timeout.Infinite);
        }
    }
}

Thanks guys, I couldn’t find the DirectoryInfo class. Will give this a go tomorrow.

I would really like an integrated sample project with a Main program from where you can instantiate FileSystem, CAN, networking etc. from separate classes and a threading sample e.g. for FileSystem.
