kDriveClient 1.0.0

🚀 kDriveClient SDK

kDriveClient is a modern C# SDK to simplify file upload and download with Infomaniak kDrive API, including:

• Automatic direct or chunked upload
• Dynamic chunk size based on your actual bandwidth
• Download with redirect support
• Built-in rate limiting (60 requests/min)
• Strong error handling (deserialized API errors)
• Native .NET logging support

📦 Installation

dotnet add package kDriveClient
dotnet add package Microsoft.Extensions.Logging.Console

⚡ Usage

Upload (automatic direct/chunked selection)

using Microsoft.Extensions.Logging;

var logger = LoggerFactory.Create(builder => builder.AddConsole())
                          .CreateLogger<KDriveClient>();

var client = new KDriveClient("your_token", "your_drive_id", logger: logger);
var file = new KDriveFile
{
    Name = "example.txt",
    DirectoryPath = "/Private/test",
    Content = File.OpenRead("example.txt"),
    CreatedAt = (int)DateTimeOffset.UtcNow.ToUnixTimeSeconds(),
    LastModifiedAt = (int)new FileInfo("example.txt").LastWriteTimeUtc.Subtract(DateTime.UnixEpoch).TotalSeconds
};

try
{
    var response = await client.UploadAsync(file);
    Console.WriteLine($"Uploaded file ID: {response.Id}");
}
catch (KDriveApiException ex)
{
    Console.WriteLine($"API error: {ex.Error}");
}

Download

// Into memory
var stream = await client.DownloadFileAsync("file_id");

Console.WriteLine($"File downloaded");

using var fs = File.Create("downloaded.txt");
await stream.CopyToAsync(fs);

Console.WriteLine($"File saved to {fs.Name}");

// Directly into a file
using var outFile = File.Create("downloaded_direct.txt");
await client.DownloadFileAsync("file_id", outFile);

Console.WriteLine($"File downloaded and saved to {fs.Name}");

⚙ Advanced features

✅ Custom parallelism

var client = new KDriveClient("your_token", "your_drive_id", true, 8);

✅ Inject your own HttpClient (for testing/mocking)

var fakeHttpClient = new HttpClient(new FakeHandler()) { BaseAddress = new Uri("https://api.infomaniak.com") };
var client = new KDriveClient("your_token", "your_drive_id", true, 4, null, httpClient: fakeHttpClient);

✅ Built-in error object

catch (KDriveApiException ex)
{
    Console.WriteLine($"Error: {ex.Error.Result}, Code: {ex.Error.Error.Code}, Description: {ex.Error.Error.Description}");
}

✅ Features

• Automatic direct or chunked upload mode based on speed test
• Dynamic chunk size calculation (~1s worth of data with safety margin)
• Download with redirect support
• Rate limit of 60 requests/min
• Deserialized error responses (no manual parsing)
• Native logger support (Microsoft.Extensions.Logging)
• Testable: inject your own HttpClient
