The items contained in a folder can be listed using the GetItems, GetFiles, or GetFolders methods. With the Xceed FileSystem, a folder is a folder regardless of if it is located on a local disk, in a zip file, in memory, or on an FTP server.
Using filters, the items that are listed can be limited by various criteria.
The following example demonstrates how to list the contents of a local folder using the steps listed below:
-
Create an instance of a DiskFolder which will represent the folder whose content to list.
-
Call the folder's GetFiles method to retrieve a listing of all the files contained in the folder and loop through the collection to print the list.
| VB.NET |
 Copy Code |
|
Imports Xceed.FileSystem
Dim folder As New DiskFolder( "c:\temp" )
Dim file As AbstractFile
For Each file in folder.GetFiles( True )
System.Diagnostics.Debug.WriteLine( file.FullName )
Next file
|
| C# |
Copy Code |
|
using Xceed.FileSystem;
DiskFolder folder = new DiskFolder( @"c:\temp" );
foreach( AbstractFile file in folder.GetFiles( true ) )
{
System.Diagnostics.Debug.WriteLine( file.FullName );
}
|
Events
All methods exposed by the Xceed FileSystem's FileSystemItem, AbstractFolder, AbstractFile, and derived classes have an overload that can be used when events are required. Events can be handled by creating an instance of the FileSystemEvents class and subscribing to the desired events. For example:
| VB.NET |
Copy Code |
|
Imports Xceed.FileSystem
Dim folder As New DiskFolder( "c:\temp" )
Dim events As New FileSystemEvents()
AddHandler events.ScanningFolder, AddressOf Me.scanning_folder
Dim file As AbstractFile
For Each file in folder.GetFiles( events, Nothing, True )
System.Diagnostics.Debug.WriteLine( file.FullName )
Next file
RemoveHandler events.ScanningFolder, AddressOf Me.scanning_folder
Private Sub scanning_folder( ByVal sender As Object, ByVal e As ScanningFolderEventArgs )
System.Diagnostics.Debug.WriteLine( e.CurrentItem.Name )
End Sub
|
| C# |
Copy Code |
|
using Xceed.FileSystem;
DiskFolder folder = new DiskFolder( @"c:\temp" );
FileSystemEvents events = new FileSystemEvents();
events.ScanningFolder += new ScanningFolderEventHandler( this.scanning_folder );
foreach( AbstractFile file in folder.GetFiles( events, null, true ) )
{
System.Diagnostics.Debug.WriteLine( file.FullName );
}
events.ScanningFolder -= new ScanningFolderEventHandler( this.scanning_folder );
private void scanning_folder( object sender, ScanningFolderEventsArgs e )
{
System.Diagnostics.Debug.WriteLine( e.CurrentItem.Name );
}
