C# WCF使用MTOM上传50Mg文件

使用WCF上传50MG文件的最佳方式是什么

我以为MTOM会自动处理这个问题。
我想我错了

即使在本地主机上运行，也会发生异常
（我假设使用外部IIS将是最糟糕的）

异常消息：

“接收对的HTTP响应时出错 .这可能是因为 未使用HTTP协议的服务端点绑定。这也可能 可能是由于服务器中止了HTTP请求上下文 （可能是由于服务关闭）。有关详细信息，请参阅服务器日志 细节。”

服务器配置：

感谢您的高级支持。

如果文件正好是50MB，那么您的maxReceivedMessageSize和maxArrayLength设置得太低，因为50MB实际上是50*1024*1024=52428800字节。此外，maxReceivedMessageSIze必须考虑消息本身的结构（SOAP信封等），而不仅仅是数据

您可以使用流式处理，这是建议的处理大文件的方法。不幸的是，wsHttpBinding无法使用它，您可能需要使用basicHttpBinding或webHttpBinding之类的工具来启用流式传输
