Passing an Exception to an HttpHandler

I am trying to pass an exception to an HttpHandler by doing the following:

catch (Exception e)
{
    byte[] exceptionData;

    MemoryStream stream = new MemoryStream();
    BinaryFormatter formatter = new BinaryFormatter(null, new StreamingContext(StreamingContextStates.Persistence));
    formatter.Serialize(stream, e);
    exceptionData = stream.ToArray();

    WebClient client = new WebClient();
    Uri handler = new Uri(ApplicationUri, "TransferException.axd");

    #if DEBUG
    ServicePointManager.ServerCertificateValidationCallback += new RemoteCertificateValidationCallback(BypassAllCertificateStuff);
    #endif

    try
    {
        client.UploadData(handler, exceptionData);
    }
    catch (WebException) { }
}

EDIT

I am getting the following exception on the client.UploadData() line. "Content-Length or Chunked Encoding cannot be set for an operation that does not write data."

EDIT

Even if I change my call to be client.UploadString(location, "THIS IS A TEST!"); it sti开发者_C百科ll fails with the same exception.

I bet that because you're never closing your stream, your array is of zero length.

Try this:

catch (Exception ex)
{
    byte[] exceptionData;

    using (MemoryStream stream = new MemoryStream())
    {
        BinaryFormatter formatter = new BinaryFormatter(
            null, new StreamingContext(StreamingContextStates.Persistence));
        formatter.Serialize(stream, ex);
        exceptionData = stream.ToArray();
    }

    using (WebClient client = new WebClient())
    {
        Uri handler = new Uri(ApplicationUri, "TransferException.axd");

#if DEBUG
        ServicePointManager.ServerCertificateValidationCallback +=
            new RemoteCertificateValidationCallback(BypassAllCertificateStuff);
#endif

        client.UploadData(handler, exceptionData);
    }
}

It turns out this was due to a .Net registered AXD handler. When I changed the extension to .axdx everything started working.
