MinIO Client SDK for .NET

MinIO Client SDK provides higher level APIs for MinIO and Amazon S3 compatible cloud storage services.For a complete list of APIs and examples, please take a look at the Dotnet Client API Reference.This document assumes that you have a working VisualStudio development environment.

Install from NuGet

To install MinIO .NET package, run the following command in Nuget Package Manager Console.

PM> Install-Package Minio

MinIO Client Example for ASP.NET

When using AddMinio to add Minio to your ServiceCollection, Minio will also use any custom Logging providers you've added, like Serilog to output traces when enabled.

using Minio;
using Minio.DataModel.Args;

public static class Program
{
    var endpoint = "play.min.io";
    var accessKey = "Q3AM3UQ867SPQQA43P2F";
    var secretKey = "zuf+tfteSlswRu7BJ86wtrueekitnifILbZam1KYY3TG";

    public static void Main(string[] args)
    {
        var builder = WebApplication.CreateBuilder();

        // Add Minio using the default endpoint
        builder.Services.AddMinio(accessKey, secretKey);

        // Add Minio using the custom endpoint and configure additional settings for default MinioClient initialization
        builder.Services.AddMinio(configureClient => configureClient
            .WithEndpoint(endpoint)
            .WithCredentials(accessKey, secretKey));

        // NOTE: SSL and Build are called by the build-in services already.

        var app = builder.Build();
        app.Run();
    }
}

[ApiController]
public class ExampleController : ControllerBase
{
    private readonly IMinioClient minioClient;

    public ExampleController(IMinioClient minioClient)
    {
        this.minioClient = minioClient;
    }

    [HttpGet]
    [ProducesResponseType(typeof(string), StatusCodes.Status200OK)]
    public async Task<IActionResult> GetUrl(string bucketID)
    {
        return Ok(await minioClient.PresignedGetObjectAsync(new PresignedGetObjectArgs()
                .WithBucket(bucketID)
            .ConfigureAwait(false));
    }
}

[ApiController]
public class ExampleFactoryController : ControllerBase
{
    private readonly IMinioClientFactory minioClientFactory;

    public ExampleFactoryController(IMinioClientFactory minioClientFactory)
    {
        this.minioClientFactory = minioClientFactory;
    }

    [HttpGet]
    [ProducesResponseType(typeof(string), StatusCodes.Status200OK)]
    public async Task<IActionResult> GetUrl(string bucketID)
    {
        var minioClient = minioClientFactory.CreateClient(); //Has optional argument to configure specifics

        return Ok(await minioClient.PresignedGetObjectAsync(new PresignedGetObjectArgs()
                .WithBucket(bucketID)
            .ConfigureAwait(false));
    }
}

MinIO Client Example

To connect to an Amazon S3 compatible cloud storage service, you need the following information

Variable name	Description
endpoint	<Domain-name> or <ip:port> of your object storage
accessKey	User ID that uniquely identifies your account
secretKey	Password to your account
secure	boolean value to enable/disable HTTPS support (default=true)

The following examples uses a freely hosted public MinIO service "play.min.io" for development purposes.

using Minio;

var endpoint = "play.min.io";
var accessKey = "Q3AM3UQ867trueSPQQA43P2F";
var secretKey = "zuf+tfteSlswRu7BJ86wtrueekitnifILbZam1KYY3TG";
var secure = true;
// Initialize the client with access credentials.
private static IMinioClient minio = new MinioClient()
                                    .WithEndpoint(endpoint)
                                    .WithCredentials(accessKey, secretKey)
                                    .WithSSL(secure)
                                    .Build();

// Create an async task for listing buckets.
var getListBucketsTask = await minio.ListBucketsAsync().ConfigureAwait(false);

// Iterate over the list of buckets.
foreach (var bucket in getListBucketsTask.Result.Buckets)
{
    Console.WriteLine(bucket.Name + " " + bucket.CreationDateDateTime);
}

Complete File Uploader Example

This example program connects to an object storage server, creates a bucket and uploads a file to the bucket. To run the following example, click on [Link] and start the project

using System;
using Minio;
using Minio.Exceptions;
using Minio.DataModel;
using Minio.Credentials;
using Minio.DataModel.Args;
using System.Threading.Tasks;
