Streams not handled properly on ObjectApis.UploadObjectXXX methods

[mmartin78]

ObjectApis.UploadObject and ObjectApis.UploadObjectAsync fail for certain types of streams. We are using the following WebApi code (some parts omitted) and it crashes:

MultipartMemoryStreamProvider provider = await Request.Content.ReadAsMultipartAsync<MultipartMemoryStreamProvider>(new MultipartMemoryStreamProvider());

foreach (HttpContent content in provider.Contents)
{
     var stream = await content.ReadAsStreamAsync();
     dynamic uploadedObj = await objects.UploadObjectAsync(fileStoreBucket, item.Id, (int)stream.Length, stream, "application/octet-stream");
}

We have tracked it down to the following code in ObjectsApi.cs which does not seem to be handling streams properly:

 if (body != null && body.GetType() == typeof(byte[])) // http body (model) parameter
            {
                localVarPostBody = body; // byte array
            }
            else if (   body != null
                     && (   body.GetType() == typeof(System.IO.FileStream)
                         || body.GetType() == typeof(System.IO.BinaryReader)
                         || body.GetType() == typeof(System.IO.BufferedStream)
                         || body.GetType() == typeof(System.IO.MemoryStream)
                         || body.GetType() == typeof(System.IO.StreamReader)
                        )
                    )
            {
                localVarPostBody = Configuration.ApiClient.toByteArray(body); // byte array
            }
            else if ( body != null )
            {
                localVarPostBody = Configuration.ApiClient.Serialize(body);
            }

We have created a quick fix in a local build, but it would be nice to be able to use the official NuGet library. The fix is simply replacing the above code with this:

localVarPostBody = Configuration.ApiClient.toByteArray(body); // byte array

We can submit a pull request if needed.

In addition, not all streams support synchronous reads.

System.NotSupportedException: Synchronous reads are not supported.

@mmartin78 - I am not sure what needs to be changed - is the whole code to be replaced by one line?
