Question

928mb文件工作正常，但是当我尝试向soap服务发送1.08GB时发生这种溢出错误（mtom chunked transfer，_service reference.cs是从wsdl生成的）。在fiddler跟踪中，我只看到请求的标题，但没有请求正文和没有响应

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);

错误堆栈跟踪如下：

System.OverflowException: Arithmetic operation resulted in an overflow.

我无法对PostFile（）调用进行调试，所以我的问题是 - 在服务器或客户端发生错误的位置？当然如何修复它？谢谢！

在堆栈跟踪中，它告诉您它是服务器端：

Server stack trace:

错误是由以下情况引起的：

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

访问该文件，看看该行发生了什么。我想要考虑托管Web服务的位置，当发生类似这样的事情时，他们会记录日志。

找出我建议的原因：

给出它发生的时间（如果它们的日志更容易找到堆栈跟踪）
发生错误时尝试执行的操作的详细说明。
