how to verify downloaded file?

[ghiboz]

hello again, here is my code that I use to download a file:

using (var response = await client.Files.DownloadAsync(file.AsFile.PathDisplay))
{
    File.WriteAllBytes(folder + "/" + realName, await response.GetContentAsByteArrayAsync());
}

but my question is: how can I check if the downloaded file is correct? is there a checksum or md5 or someother thing?

thanks in advance

The Dropbox API doesn't currently offer any sort of hash or checksum, but I'll be sure to pass this along as a feature request. If the download is interrupted though, an exception will be thrown.

Hi, What news this issues? Thx.

Recently, the API "FileMetadata" objects got a new "content_hash" field.

• More information about that field: https://www.dropbox.com/developers/reference/content-hash
• C# code to compute the hash: https://github.com/dropbox/dropbox-api-content-hasher/tree/master/csharp

thx @cakoose it's very good. May be add DropboxContentHasher in sdk?

Thanks Andrew! I can't make any promises, but we'll keep this open as a request to integrate that directly into the SDK.
