DropboxClient dbx = new DropboxClient(user.DropboxAccessToken,10,null,httpClient);

{
var ufile =await response.GetContentAsStreamAsync();
}

No, unfortunately I don't believe the .NET SDK offers a way to track progress of the download. I'll send this along as a feature request though.

I'm assuming the code above works for you? I am trying to use similar code and the file isn't downloading for some reason. I don't get an error message, I just get a blank screen. I have the using(var response = await.dbx.Files.DownloadAsync("/" + file)
{

}

What code actually downloads it and where does it download it? Does the response.GetContentAsStreamAsync() function download the file?

Hi Brandon, it sounds like your question is more about downloading files in general when using the .NET SDK, as opposed to getting progress of a download. Can you open a new thread with the details of any issue(s) you're having so we can help you specifically without spamming Manjit? Thanks in advance!

You can now track progress using GetContentAsStreamAsync. E.g., you can do something like:

 var response = await client.Files.DownloadAsync(path);
ulong fileSize = response.Response.Size;
const int bufferSize = 1024 * 1024;

var buffer = new byte[bufferSize];

using (var stream = await response.GetContentAsStreamAsync())
{
    using (var file = new FileStream("Test", FileMode.OpenOrCreate))
    {
        var length = stream.Read(buffer, 0, bufferSize);

        while (length > 0)
        {
            file.Write(buffer, 0, length);
            var percentage = 100 * (ulong)file.Length / fileSize;
            // Update progress bar with the percentage.
            // progressBar.Value = (int)percentage
            Console.WriteLine(percentage);

            length = stream.Read(buffer, 0, bufferSize);
        }
    }
}
