PostSharp message to WCF REST service

Question

I am having problems uploading images to the server via RestSharp.

I have a Wcf Rest service that accepts a Stream. If I use the code below, I always get this exception:

Protocol ViolationException The bytes that must be written to the stream exceed the specified byte size of the content length.

What settings do I need to configure ... setting the content length header does not seem to matter.

The server side does not receive the image, but a slightly smaller stream of bytes.

Any help was appreciated.

Client (test) code:

byte[] byteArray = File.ReadAllBytes("small.jpg"); request.AddHeader("Content-Length", int.MaxValue.ToString());//doesn't matter what length I put here request.AddFile("image/jpeg", (requestStream) => { using (var ms = new MemoryStream(byteArray)) { ms.CopyTo(requestStream, byteArray.Length);//doesn't matter whether I add second param or not ms.Flush(); ms.Close(); } }, "sample", "image/jpeg"); request.Method = Method.POST; client.ExecuteAsync(request, (response, a) => { Assert.IsNotNull(response.Content); string content = response.Content; resetEvent.Set(); }); 

Service Code (returns the URL of the saved image)

 [OperationContract] [WebInvoke(UriTemplate = "upload/{fileName}/{fileExtension}/{id}", Method = "POST", BodyStyle = WebMessageBodyStyle.Bare, ResponseFormat = WebMessageFormat.Json)] Message UploadPhoto(string fileName, String fileExtension, string id, Stream fileContents);

The Content-Length header is set automatically based on the contents of the request body, so you do not need to explicitly specify it.
