Supported adapters

Adapter	Package	NuGet
Local adapter	SharpGrip.FileSystem
AmazonS3	SharpGrip.FileSystem.Adapters.AmazonS3
AzureBlobStorage	SharpGrip.FileSystem.Adapters.AzureBlobStorage

Supported operations

For a full list of the supported operations please see the IFileSystem interface.

Usage

Instantiation

var adapters = new List<IAdapter>
{
    new LocalAdapter("adapterPrefix", "adapterRootPath")
};

// Instantiation option 1.
var fileSystem = new FileSystem(adapters);

// Instantiation option 2.
var fileSystem = new FileSystem();
fileSystem.Adapters = adapters;

Local adapter

var adapters = new List<IAdapter>
{
    new LocalAdapter("local1", "/var/files"),
    new LocalAdapter("local2", "D:\\Files")
};

var fileSystem = new FileSystem(adapters);

AmazonS3 adapter

// Amazon connection.
var amazonClient = new AmazonS3Client("awsAccessKeyId", "awsSecretAccessKey", RegionEndpoint.USEast2);

var adapters = new List<IAdapter>
{
    new LocalAdapter("local", "/var/files"),
    new AmazonS3Adapter("amazon", "/Files", amazonClient, "bucketName")
};

var fileSystem = new FileSystem(adapters);

AzureBlobStorage adapter

// Azure connection.
var blobServiceClient = new BlobServiceClient("connectionString");
var azureClient = blobServiceClient.GetBlobContainerClient("blobContainerName");

var adapters = new List<IAdapter>
{
    new LocalAdapter("local", "/var/files"),
    new AzureBlobStorageAdapter("azure", "/Files", azureClient)
};

var fileSystem = new FileSystem(adapters);

AzureFileStorage adapter

// Azure connection.
var azureClient = new ShareClient("connectionString", "shareName");

var adapters = new List<IAdapter>
{
    new LocalAdapter("local", "/var/files"),
    new AzureFileStorageAdapter("azure", "/Files", azureClient)
};

var fileSystem = new FileSystem(adapters);

Dropbox adapter

// Dropbox connection.
var dropboxClient = new DropboxClient("oAuth2AccessToken");

var adapters = new List<IAdapter>
{
    new LocalAdapter("local", "/var/files"),
    new DropboxAdapter("dropbox", "/Files", dropboxClient)
};

var fileSystem = new FileSystem(adapters);

MicrosoftOneDrive adapter

// Microsoft connection.
var scopes = new[] {"https://graph.microsoft.com/.default"};
var tenantId = "tenantId";
var confidentialClient = ConfidentialClientApplicationBuilder
    .Create("clientId")
    .WithAuthority($"https://login.microsoftonline.com/{tenantId}/v2.0")
    .WithClientSecret("clientSecret")
    .Build();
var oneDriveClient = new GraphServiceClient(new DelegateAuthenticationProvider(async requestMessage =>
    {
        var authResult = await confidentialClient.AcquireTokenForClient(scopes).ExecuteAsync();
        requestMessage.Headers.Authorization = new AuthenticationHeaderValue("Bearer", authResult.AccessToken);
    })
);

var adapters = new List<IAdapter>
{
    new LocalAdapter("local", "/var/files"),
    new MicrosoftOneDriveAdapter("onedrive", "/Files", oneDriveClient, "driveId")
};

var fileSystem = new FileSystem(adapters);

SFTP adapter

// SFTP connection.
var privateKeyFile = new PrivateKeyFile("/home/userName/.ssh/id_rsa");
var privateKeyAuthenticationMethod = new PrivateKeyAuthenticationMethod("userName", privateKeyFile);
var sftpConnectionInfo = new ConnectionInfo("hostName", "userName", privateKeyAuthenticationMethod);
var sftpClient = new SftpClient(sftpConnectionInfo);

var adapters = new List<IAdapter>
{
    new LocalAdapter("local", "/var/files"),
    new SftpAdapter("sftp", "/var/files", sftpClient)
};

var fileSystem = new FileSystem(adapters);

Example operations

// Azure connection.
var azureClient = new ShareClient("connectionString", "shareName");

// Dropbox connection.
var dropboxClient = new DropboxClient("oAuth2AccessToken");

var adapters = new List<IAdapter>
{
    new LocalAdapter("local", "/var/files"),
    new AzureFileStorageAdapter("azure", "/Files", azureClient),
    new DropboxAdapter("dropbox", "/Files", dropboxClient)
};

// Copies a file from the `local` adapter to the `azure` adapter.
await fileSystem.CopyFileAsync("local://foo/bar.txt", "azure://bar/foo.txt");

// Moves a file from the `azure` adapter to the `dropbox` adapter.
await fileSystem.MoveFileAsync("azure://Foo/Bar.txt", "dropbox://Bar/Foo.txt");

// Writes string contents to the `azure` adapter.
await fileSystem.WriteFileAsync("azure://Foo.txt", "Bar!");

// Reads a text file from the `dropbox` adapter.
var contents = fileSystem.ReadTextFileAsync("dropbox://Foo.txt");
