Download via Stream

[Nikey646]

It shouldn't be a requirement to download a file to a local path. There should be the capability of downloading the file to any writable stream.

The best (in my opion) way to handle this would be creating a download method that returns the response stream that correlates to the file. EG, if using a Http Client, returning response.Content.ReadAsStreamAsync() might be an option.

The direct stream along with the streams progress (IProgress) can be access using the "DownloadAsync" method in root of the client object. Here is an example:

var files = new string[] { @"c:\my\directory\file1.txt", "file2.bat" };

foreach (var fileName in files)
{
  using (var stream = File.Create(fileName))
  {
      var results = await Client.DownloadAsync("[BucketName]", fileName, stream);
  }
}

This doesn't quite achieve my objective in the end. UItimately, I wanted to start the download request but not actually download any part of the file, because it was just to check if the file existed. In the end, i just ended up implementing a manual HTTP Head request to check the status code (looking for a successful status code to indicate the file existed).

Got it. I have a better understanding of what you are trying to do. You can download the status/results of a file by passing "null" in the stream. This will automatically handle passing a head request HttpCompletionOption.ResponseHeadersRead and will not download any content. Here is an example:

var results = await Client.DownloadAsync("[BucketName]", "file.txt", null) 

However, to download the actual content you will have to execute the request again without a "null" stream. Agreed not the cleanest way to handle it.
