using MultipartFormDataStreamProvider and ReadAsMultipartAsync
Issues with MultipartFormDataStreamProvider
submitting files to a web api
File upload using MultipartMemoryStreamProvider

原生的MultipartStreamProvider，其GetLocalFileName()會使用Guid來命名，
若要使用自己的命名方式，需自行實作：

        public virtual string GetLocalFileName(HttpContentHeaders headers)
        {
            if (headers == null)
            {
                throw Error.ArgumentNull("headers");
            }

            return String.Format(CultureInfo.InvariantCulture, "BodyPart_{0}", Guid.NewGuid());
        }

Dealing with the frustrations of trying to test the ASP.NET Web API MultipartFormDataStreamProvider.

    public class CustomMultipartFormDataStreamProvider : MultipartFormDataStreamProvider
    {
        public CustomMultipartFormDataStreamProvider(string path)
            : base(path)
        {
        }

        public override string GetLocalFileName(System.Net.Http.Headers.HttpContentHeaders headers)
        {
            var name = !string.IsNullOrWhiteSpace(headers.ContentDisposition.FileName) ? headers.ContentDisposition.FileName : "NoName";
            return name.Replace("\"", string.Empty);
        }
    }
