如何使用

WCF 解析/反序列化从 Web 服务获得的 MTOM/XOP 响应？我在磁盘上有响应。我复制了下面的回复：

任何帮助都非常感谢。

解析/反序列化 MTOM/XOP Data .NET

可以使用 WCF 类反序列化响应，如下所示。但在我们继续之前，此 MTOM 无效 - Content-Type标头的参数boundary格式不正确。由于它包含"？"字符，因此需要引用（查看MIME RFC，第5.1节，token的定义）。

现在，要反序列化它，您需要使用 MTOM 阅读器打开文档 - XmlDictionaryReader.CreateMtomReader 会为您提供确切的答案。创建该读取器后，可以将其传递给DataContractSerializer以反序列化对象。下面的代码显示了如何做到这一点。

this is a binary content; it could be anything but for simplicity I'm using text
