How To Accept a File POST

by

I’m surprised that a lot of you seem to want to save files on the server. Solution to keep everything in memory is as follows:

[HttpPost("api/upload")]
public async Task<IHttpActionResult> Upload()
{
    if (!Request.Content.IsMimeMultipartContent())
        throw new HttpResponseException(HttpStatusCode.UnsupportedMediaType); 

    var provider = new MultipartMemoryStreamProvider();
    await Request.Content.ReadAsMultipartAsync(provider);
    foreach (var file in provider.Contents)
    {
        var filename = file.Headers.ContentDisposition.FileName.Trim('\"');
        var buffer = await file.ReadAsByteArrayAsync();
        //Do whatever you want with filename and its binary data.
    }

    return Ok();
}
