Cannot get thumbails from GetThumbnailAsync

le h.

I don't see any "icon","thumbail"....

using (var dbx = new DropboxClient(Token))
{
var list = await dbx.Files.ListFolderAsync(path);
foreach(var item in list.Entries)
{
list1 = await dbx.Files.GetThumbnailAsync(item.AsFile.PathLower, null, ThumbnailSize.W64h64.Instance);
RootObject obj = new RootObject();

obj.thumbail = list1.Response.........................;
arrays.Add(obj);
}
}

return arrays;
}

The GetThumbnailAsync method gives you IDownloadResponse<FileMetadata>. As shown in the documentation there, there are three different GetContent methods you can call on the response to get the content of the thumbnail requested.

For example, you could get the thumbnail data as a byte array by using: (in your sample though response is list1)

response.GetContentAsByteArrayAsync()

.I can't. Can you write code clearly? I don't know whatever you said.

Here's a simple example that works for me to save a thumbnail of a file in Dropbox at "/test.jpg" to a local file on my computer:

public async Task GetThumbnail(string path)
{
 using (var response = await client.Files.GetThumbnailAsync(path, null, ThumbnailSize.W64h64.Instance))
 {
 using (var fileStream = File.Create ("/destination/path/test_thumb.jpg")) {
 var thumbStream = await response.GetContentAsStreamAsync();
 thumbStream.CopyTo (fileStream);
 };
 }
}

await GetThumbnail("/test.jpg");

Just be sure to set your remote path and local destination accordingly.

your mean that I have to convert byte to getting thumbnail.
