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.
To install MinIO .NET package, run the following command in Nuget Package Manager Console.
PM> Install-Package MinioTo 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 MinioClient 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);
}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
