Send and receive large file over streams in ASP.NET Web Api C#

Question

I\'m working on a project where I need to send large audio files via streams from a client to a server. I\'m using the ASP.NET Web Api to communicate between client and serv

Answer 1

if I send a large file my server gets a "outofmemoryexception"

Well, it's reading the entire stream into memory right here:

byte[] receivedBytes = await Request.Content.ReadAsByteArrayAsync();

What you want to do is copy the stream from one location to another, without loading it all into memory at once. Something like this should work:

[HttpPost]
[ActionName("AddAudio")]
public async Task<IHttpActionResult> AddAudio([FromUri]string name)
{
  try
  {
    string file = Path.Combine(@"C:\Users\username\Desktop\UploadedFiles", fileName);
    using (FileStream fs = new FileStream(file, FileMode.Create, FileAccess.Write,
        FileShare.None, 4096, useAsync: true))
    {
      await Request.Context.CopyToAsync(fs);
    }
    return Ok();
  }
  catch (Exception ex)
  {
    return BadRequest("ERROR: Audio could not be saved on server.");
  }
}
