HttpRequest.Files is empty when posting file through HttpClient

Question

Server-side:

    public HttpResponseMessage Post([FromUri]string machineName)
    {
        HttpResponseMessage result = null;
        var httpRequest = Http         


        

Answer 1

Everything looks good in your code except the content type which should be multipart/form-data. Please try changing your code to reflect the correct content type:

content.Headers.ContentType = new MediaTypeHeaderValue("multipart/form-data");

You might want to refer to this post as to why setting the content type to application/octet-stream doesn't make sense from client side.
