C＃肥皂客户端System.OverflowException：算术运算导致溢出

Question

928mb file works ok, but this overflow error happens when I try to send 1.08GB to the soap service (mtom chunked transfer, _service reference.cs is generated from wsdl). In the fiddler tracing I see only headers of the request, but no request body and no response

Relevant code:

var httpsTransportBindingElement = new HttpsTransportBindingElement
{
    MaxReceivedMessageSize = int.MaxValue,
    TransferMode = TransferMode.Streamed //Chunked transfer
};
var binding = new CustomBinding();
var mtomEncoding = new MtomMessageEncodingBindingElement(MessageVersion.Soap12, Encoding.UTF8);
mtomEncoding.ReaderQuotas.MaxStringContentLength = int.MaxValue;
binding.Elements.Add(mtomEncoding);
binding.Elements.Add(httpsTransportBindingElement);
binding.SendTimeout = TimeSpan.FromHours(1);
binding.ReceiveTimeout = TimeSpan.FromMinutes(5);
_service = new FileuploadSoapPortTypeClient(binding, new EndpointAddress(configuration.HttpUploadUrl));
_service.PostFile(request);

And the error stacktrace is as follows:

System.OverflowException: Arithmetic operation resulted in an overflow.

I cant debug this further than to the PostFile() call, so my question is - where does the error occur, in the server or on my client? and of course how to go about fixing it? Thanks!

From in the stack trace it is telling you that it is server side:

Server stack trace:

The error is caused by something which is happening at:

at MyServiceClient.FileuploadSoapPortType.PostFile(UploadRequest request) in C:\MyServiceClient\Reference.cs:line 8473 

Access that file and see what is happening on that line. I'd like to think where ever the web service is hosted they have logs for when something like this occurs.

To find out why I suggest:

• giving the time it occured ( if they have logs its easier to find the stack trace)
• Detailed description of what you tried to do when the error occurred.
