FileSystemProvider

Namespace: Wisej.Core

Assembly: Wisej.Framework (4.1.0.0)

Default implementation of IFileSystemProvider. Provides access to the server's file system.

C#

public class FileSystemProvider : IFileSystemProvider

VB.NET

Public Class FileSystemProvider
    Inherits IFileSystemProvider

Constructors

FileSystemProvider()

Initializes a blank instance of FileSystemProvider.

FileSystemProvider(root, name)

Creates a new instance of the FileSystemProvider class with the specified root and name . The root is added in front of all path arguments passed to all methods in this class.

Name	Type	Description
root	String	The root path of this file system.
name	String	The name of this file system.

The root path is also the current directory path.

Properties

Icon

Image: Returns or sets the icon that represents the file system. (Default: null)

IconSource

String: Returns or sets the icon name or URL that represents the file system. (Default: "resource.wx/icon-storage.svg")

Name

String: Returns or sets the name of this root. This is the name that should be shown to the user.

Root

String: Returns or sets the root path for the file system. All file system operations in the implementation class are expected to be limited to the root.

Implements

Name	Description
IFileSystemProvider	Abstracts access to the file system. Implementations of this interface are used by the file dialogs and other components that need to interact with the file system. Wisej provides the built-in default implementation for the standard disk-based file system and a number of alternative implementations in the Wisej extensions, such as: Amazon S3, Google Drive, and Microsoft OneDrive.
