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

928mb文件可以正常工作，但是当我尝试向soap服务发送1.08GB时发生此溢出错误（mtom chunked transfer，_service reference.cs从wsdl生成）。在提琴手跟踪我看到的只是请求的头，但没有要求的身体也没有反应C＃soap客户端System.OverflowException：算术运算导致溢出

相关代码：

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);

和错误堆栈跟踪如下：

System.OverflowException: Arithmetic operation resulted in an overflow.

我不能除PostFile（）调用外，进一步调试，所以我的问题是 - 错误发生在服务器还是我的客户端？当然如何去解决它？谢谢！

'服务器堆栈跟踪：'问题是在服务器 –

谢谢，这将是一个答案，如果你也能告诉我如何去解释它的地方出现错误的服务提供商？通常我会收到肥皂故障信息，我可以将它们发送给他们进行审查，但在这种情况下没有回应 – Succenna

这里发生了什么？ C：\ MyServiceClient \ Reference.cs：line 8473 –

从堆栈跟踪它告诉你，这是服务器端：

Server stack trace:

错误是由什么引起的，其在发生：

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

访问该文件，看看有什么正在发生这一行。我想想想，当发生这样的事情时，他们已经记录了Web服务的托管位置。

要找出原因，我建议：

给它发生的时间（如果他们有记录其更容易找到堆栈跟踪）的你试图做什么错误发生时
详细说明。
