AWS SDKを使ってさくらのオブジェクトストレージにアクセスするやつ

sakura_objstorage.cs

private const string ACCESS_KEY_ID = "アクセスキーID";
private const string SECRET_ACCESS_KEY = "シークレットアクセスキー";

public static void GetObjectFromObjStorage(string downloadFolder)
{

	var config = new AmazonS3Config
	{
		ServiceURL = "https://b.sakurastorage.jp/"
	};
	
	var credentials = new BasicAWSCredentials(ACCESS_KEY_ID, SECRET_ACCESS_KEY);
	IAmazonS3 s3Client = new AmazonS3Client(credentials, config);

	var objects = s3Client.ListObjects(ACCESS_KEY_ID).S3Objects;

	// 例として列挙したオブジェクトの中でサイズが最大の物を返す
	objects.Sort((x, y) => (int)(y.Size - x.Size));
	var obj = objects.First();

	Console.WriteLine("ETag: " + obj.ETag);
	Console.WriteLine("Key: " + obj.Key);
	Console.WriteLine("Size: " + obj.Size);

	var path = Path.Combine(downloadFolder, Path.GetFileName(obj.Key));
	Console.WriteLine("Downloading: " + path);

	s3Client.DownloadToFilePath(ACCESS_KEY_ID, obj.Key, path, null);
	Console.WriteLine("complete");
	Console.Read();
