A simple abstraction layer over file system like APIs

Currently implemented:

• FileSystem (CIFS)
• In Memory (useful for Unit Testing)
• FTP/FTPS via AlexFTPS
• SFTP via SshNet
• Dropbox via DropNet
• ZipFile via DotNetZip

Nuget: install-package VirtualPath

Direct instanciation of provider:

using(var storage = new InMemoryVirtualPathProvider())
{
	var file = storage.GetFile("/info.txt");
	var info = file.ReadAllText();
}

Using VirtualPathProvider factory:

// general usage:
var storage = VirtualPathProvider.Open(providerName, config);

// Exemples:
VirtualPathProvider.Open("Memory")
VirtualPathProvider.Open("FileSystem", "C:\\Temp\\")
VirtualPathProvider.Open("FTP", "host=ftp.company.com;username=login;password=password")
VirtualPathProvider.Open("SFTP", "host=ftp.company.com;username=login;password=password")
VirtualPathProvider.Open("Dropbox", "apikey=;apisecret=;usertoken=;usersecret=")

You can also pass anonymous objects to specify constructor parameters:

var config = new { host = "ftp.company.com", username = "login", password = "password" };
VirtualPathProvider.Open("FTP", config);

• If you pass a string:
  • split it on ';' then build IDict<string,string> by splitting on '=',
  • if no key => wildcard key (works for single parameter constructors like FileSystem)
• If passing an object, build a IDict<string,object> from properties

Finding the constructor:

• filter constructors with matching parameter count
• if one result: return constructor
• filter remaining constructors on parameter names
• if one result: return constructor
• filter remaining on parameter types (including conversions if passed strings)
• if one result: return constructor

• InMemoryVirtualPathProvider: Memory
• FileSystemVirtualPathProvider: FileSystem, FS
• FtpVirtualPathProvider: AlexFTPS, FTP
• SftpVirtualPathProvider: SshNet, SFTP
• DropboxVirtualPathProvider: DropNet, Dropbox
• ZipVirtualPathProvider: Zip, DotNetZip

• FTPS by providerName
• CIFS credentials in FileSystem
• WebDAV
• Cross provider methods
  • CopyFile(string virtualPath, IVirtualFile file)
  • MoveFile(string virtualPath, IVirtualFile file)
  • etc

• Directory Move / Copy ?
• Amazon S3
• Google Drive
• Transactional PathProvider (InMemory commiting to FileSystem for example)

• ServiceStack for basic implementation of IVirtualPathProvider/FileSystem/InMemory
• AlexFTPS
• SshNet
• DropNet
• DotNetZip
