Large File Download
Hello,
I used Dropbox SDK for .NET to download a large file of size 1.3 GB but the program hung.
using (var response = await dbx.Files.DownloadAsync(path + "/" + file))
{
byte[] buffer = await response.GetContentAsByteArrayAsync();
}
I then used Dropbox REST API - "https://content.dropboxapi.com/2/files/download"
with Authorization and Dropbox-API-Arg (with path as argument) as headers.
For smaller files the Rest Api worked, but for the 1.3 GB file download, the program threw "Out of Memory Exception".
How do I perform a download of such a larger file with size > 1GB.
Thanks,
Gagan
- You appear to be trying to read the entirety of the contents into memory, which is likely to fail for large files like this.
You'll probably want to use GetContentAsStreamAsync in the SDK (instead of GetContentAsByteArrayAsync), so you can access the contents via a stream, instead of reading it all into memory:
