# MinIO Client SDK for .NET  [![Slack](https://slack.min.io/slack?type=svg)](https://slack.min.io)

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](https://docs.min.io/docs/dotnet-client-api-reference).This document assumes that you have a working VisualStudio development environment.

## Minimum Requirements
 * .NET 5.0
 * Visual Studio 2017

## Install from NuGet

To install [MinIO .NET package](https://www.nuget.org/packages/Minio/), run the following command in Nuget Package Manager Console.
```powershell
PM> Install-Package Minio
```
## MinIO Client Example
To connect to an Amazon S3 compatible cloud storage service, you will need to specify the following parameters.

| Parameter  | Description|
| :---         |     :---     |
| endpoint   | URL to object storage service.   |
| accessKey | Access key is the user ID that uniquely identifies your account. |
| secretKey | Secret key is the password to your account. |
| secure | Enable/Disable HTTPS support. |

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

```cs
using Minio;

// Initialize the client with access credentials.
private static MinioClient minio = new MinioClient()
                                    .WithEndpoint("play.min.io")
                                    .WithCredentials("Q3AM3UQ867SPQQA43P2F",
                                             "zuf+tfteSlswRu7BJ86wekitnifILbZam1KYY3TG")
                                    .WithSSL()
                                    .Build();

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

// Iterate over the list of buckets.
foreach (Bucket 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
```cs
using System;
using Minio;
using Minio.Exceptions;
using Minio.DataModel;
using System.Threading.Tasks;

namespace FileUploader
{
    class FileUpload
    {
        static void Main(string[] args)
        {
            var endpoint  = "play.min.io";
            var accessKey = "Q3AM3UQ867SPQQA43P2F";
            var secretKey = "zuf+tfteSlswRu7BJ86wekitnifILbZam1KYY3TG";
            try
            {
                var minio = new MinioClient()
                                    .WithEndpoint(endpoint)
                                    .WithCredentials(accessKey,
                                             secretKey)
                                    .WithSSL()
                                    .Build();
                FileUpload.Run(minio).Wait();
            }
            catch (Exception ex)
            {
                Console.WriteLine(ex.Message);
            }
            Console.ReadLine();
        }

        // File uploader task.
        private async static Task Run(MinioClient minio)
        {
            var bucketName = "mymusic";
            var location   = "us-east-1";
            var objectName = "golden-oldies.zip";
            var filePath = "C:\\Users\\username\\Downloads\\golden_oldies.mp3";
            var contentType = "application/zip";

            try
            {
                // Make a bucket on the server, if not already present.
                bool found = await minio.BucketExistsAsync(bucketName);
                if (!found)
                {
                    await minio.MakeBucketAsync(bucketName, location);
                }
                // Upload a file to bucket.
                await minio.PutObjectAsync(bucketName, objectName, filePath, contentType);
                Console.WriteLine("Successfully uploaded " + objectName );
            }
            catch (MinioException e)
            {
                Console.WriteLine("File Upload Error: {0}", e.Message);
            }
        }
    }
}
```
