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

Question

928mb 文件工作正常，但是当我尝试将 1.08GB 发送到 SOAP 服务(mtom 分块传输，_service引用.cs是从 wsdl 生成的(时会发生此溢出错误。在提琴手跟踪中，我只看到请求的标头，但没有请求正文，也没有响应

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：

我无法比 PostFile(( 调用更进一步地调试它，所以我的问题是 - 错误发生在哪里，在服务器或我的客户端上？ 当然如何修复它？谢谢！

从堆栈跟踪中，它告诉您它是服务器端：

Server stack trace:

该错误是由以下位置发生的情况引起的：

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

访问该文件并查看该行上发生的情况。我想想想 Web 服务托管在哪里，他们都有发生类似事情时的日志。

要找出我建议的原因：

• 给出它发生的时间(如果他们有日志，则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。
