Upload all files in folder directory to Google Cloud Storage without loop

Question

How to upload all files in folder to Google Storage Cloud without loop. Here I try use C# with one file upload :

public async Task<ActionResult> Upload(IFormFile file)
{
    string contentRootPath = _hostingEnvironment.ContentRootPath;

    var credential = GoogleCredential.FromJson(System.IO.File.ReadAllText(contentRootPath + "/credentials.json"));

    StorageClient storageClient = StorageClient.Create(credential);

    var objectName = MakeObjectName();

    var imageObject = await storageClient.UploadObjectAsync(
        bucket: CloudConfig.BUCKET,
        objectName: objectName,
        contentType: file.ContentType,
        source: file.OpenReadStream(),
        options: new UploadObjectOptions { PredefinedAcl = PredefinedObjectAcl.PublicRead }
    );

    return Ok(new DropzoneInfo { Name = file.FileName, ObjectName = objectName, Link = imageObject.MediaLink, Size = file.Length});
}

You have a controller action that accepts a single uploaded file. Use a List<IFormFile> in your controller action - see this answer: Submitting multiple files to ASP.NET controller accepting an ICollection<IFormFile>

There is an attribute for uploading directories: <input type="file" webkitdirectory> ( How do I use Google Chrome 11's Upload Folder feature in my own code? )

These browsers support it: Edge, Safari, Firefox, Chrome, Opera ( https://caniuse.com/#feat=input-file-directory )
