Use the following
MonoTouch code to easily list all the files in your Applications Documents folder. First create a regular IPhone Navigation based Project.
Open "RootViewController.xib.cs" and add the following code. I only added five lines of code. I've put a "//EDITED:" comment in front of each line that I added. Make sure to add a "using System.Linq" to the top of the file as well.
partial class RootViewController : UITableViewController
{
//EDITED: list to hold file names.
private System.Collections.Generic.List<string> dataItems = null;
public RootViewController (IntPtr handle) : base(handle)
{
}
public override void ViewDidLoad ()
{
base.ViewDidLoad ();
//Show an edit button
//NavigationItem.RightBarButtonItem = EditButtonItem;
//EDITED: build list of files.
string path = Environment.GetFolderPath (Environment.SpecialFolder.Personal);
dataItems = System.IO.Directory.GetFiles(path).ToList();
this.TableView.Source = new DataSource (this);
}

By default your app won't have any files in the documents folder but you can manually add some. In you user accounts "~/Library/Application Support/IPhone Simulator/" directory there will be multiple folders for each version of IPhone OS you can test. Pick the one you'll be test and put some files in the "Documents" folder.
Once that is done you can run your application in the simulator and it should give you the list of files you added to the "Documents" folder. Pretty simple huh?
I'll be using this code in a prototype that uploads
Cycorder recordings from my IPhone 3G (I have a separate app for 3GS to use the built-in video recording) to
Qwikcast, my company's WebCast presentation software. I'll be using SSH to
create a symbolic link so Cycorder saves it's recordings to my applications Documents folder. Then I'll be doing a HTTP Upload to the Qwikcast web server where the video will automatically be encoded, published to a streaming media server, and then available on a "catalog" page for viewing (iPad and iPhone compatible of course) !
.
does not have a regular "line in" that would work with the Kensington Bluetooth kit. :(
