Use the AWS SDK for .NET with Backblaze B2

You can take advantage of Backblaze B2 Cloud Storage using the AWS SDK for .NET alongside the Backblaze S3-Compatible API.

This example demonstrates how to use the AWS SDK for .NET with Backblaze B2:

using Amazon.S3;
using Amazon.S3.Model;
namespace Backblaze_B2_Samples
{
  public class S3_Basics
  {
    public static async Task Main(string[] args)
    {
      /*
        Create an Amazon S3 client object. The constructor looks for
        credentials in the following order:
        1. Explicitly set in the AmazonS3Client() constructor
        2. A credentials profile with the name specified by a value in AWSConfigs.AWSProfileName.
        3. A credentials profile with the name specified by the AWS_PROFILE environment variable.
        4. The [default] credentials profile.
        5. AWS_ACCESS_KEY_ID, AWS_SECRET_ACCESS_KEY, and AWS_SESSION_TOKEN environment variables - a
           SessionAWSCredentials object is created from them, if they're all non-empty.
        6. AWS_ACCESS_KEY_ID and AWS_SECRET_ACCESS_KEY environment variables - a BasicAWSCredentials
           object is created from them, if they're both non-empty.
        Since AWSSDK.Core 3.7.108.0, you can set AWS_ENDPOINT_URL, rather than creating an AmazonS3Config
        object with a custom ServiceURL and passing it to the AmazonS3Client constructor.
      */
      IAmazonS3 client = new AmazonS3Client();
      // Create a bucket and upload something into it
      string bucket = "dotnetv2-sdk-sample" + Guid.NewGuid();
      string key = "hello_world.txt";
      try
      {
        // The AWS SDK for .NET maps the CreateBucket operation to 'PutBucket'
        await client.PutBucketAsync(new PutBucketRequest { BucketName = bucket });
        await client.PutObjectAsync(new PutObjectRequest { BucketName = bucket,
          Key = key, ContentBody = "Hello, world!" });
        Console.WriteLine($"Successfully uploaded data to {bucket}{key}");
      }
      catch (AmazonS3Exception ex)
      {
        Console.WriteLine($"Error: {ex.Message}");
      }
    }
  }
}
