DownloadAttachment as Stream

[emrecaglar]

A stream-returning method is required to access the file from memory without writing it to disk.

DownloadAttachmentAsync like

public async Task<Stream> DownloadAttachmentAsStreamAsync(CouchAttachment attachment, CancellationToken cancellationToken = default)
{
    Check.NotNull(attachment, nameof(attachment));

    if (attachment.Uri == null)
    {
        throw new InvalidOperationException("The attachment is not uploaded yet.");
    }

    return await NewRequest()
        .AppendPathSegment(attachment.DocumentId)
        .AppendPathSegment(Uri.EscapeUriString(attachment.Name))
        .WithHeader("If-Match", attachment.DocumentRev)
        .GetStreamAsync(cancellationToken)
        .ConfigureAwait(false);
}

I'm not sure if it helps or not, but I wrote a method to return the data as bytes using Flurl:

return await mCouchDbOptions.Endpoint.WithBasicAuth(mCouchDbOptions.Username, mCouchDbOptions.Password)
.AppendPathSegment(databaseName)
.AppendPathSegment(Uri.EscapeUriString(document.Id))
.AppendPathSegment(Uri.EscapeUriString(attachmentName))
.WithHeader("If-Match", document.Rev)
.GetBytesAsync(cancellationToken);
