通过C＃使用REST api将大文件放入一个驱动器

Question

I want to put a large file (1.4 gb) via rest api to onedrive.

HttpWebRequest webRequest = (HttpWebRequest)WebRequest.Create(myUri);
webRequest.Timeout = 12 * 60 * 60 * 1000;
webRequest.AllowAutoRedirect = true;
webRequest.ReadWriteTimeout = 12 * 60 * 60 * 1000;
webRequest.AllowReadStreamBuffering = false;
webRequest.AllowWriteStreamBuffering = false;
webRequest.SendChunked = true;
webRequest.KeepAlive = false;
webRequest.ProtocolVersion = HttpVersion.Version10;
webRequest.ServicePoint.ConnectionLimit = 1;
webRequest.ContinueTimeout = 12 * 60 * 60 * 1000;

webRequest.Method = "PUT";
using (Stream stream = webRequest.GetRequestStream())
{
    stream.WriteTimeout = 12 * 60 * 60 * 1000;
    writeToStream(stream);
    stream.Flush();
    stream.Close();
}

But at arround 200mb I receive an IOException (The underlying connection was closed. Unexpected error during write)

I've searched the internet and found some recommendation to set KeepAlive to false, set the HttpVersion and the ConnectionLimit , as you can see.

I've tried it with different settings, but it is always the same.

I can not use HttpClient , because of Memory consumption.

The code works with small files.

Answer 2

Have you tried with LIVE SDK for windows runtime.

Hope with this, you can achieve , as it provides asyc upload.

Note: This is off-topic. But still i thought of sharing.I have tried uploading to Amazon S3 using AWS SDK, it does work, and i have tried with around 800MB file.

It is currently not possible to upload a file larger than 100MB via the REST API. Hopefully that's a situation that's improved in the future.
