解析/反序列化MTOM / XOP数据.NET [英] Parse/deserialize MTOM/XOP Data .NET

问题描述

如何解析/反序列化 MTOM / XOP 响应是从使用WCF的Web服务获得的？我在磁盘上有响应。我已在下面复制了响应：

How can I parse/deserialize a MTOM/XOP response that I get from a web service using WCF? I have the response on disk. I have copied the response below:

非常感谢您的帮助。

推荐答案

您可以使用WCF类反序列化响应，如下所示下面。但是在继续之前，此MTOM无效- Content-Type 标头的参数 boundary 格式错误。由于它包含'？'字符，因此需要加引号（请参见 MIME RFC ，第5.1节，令牌的定义）。

You can deserialize the response using the WCF classes, as I'll show below. But before we proceed, this MTOM is invalid - the parameter boundary of the Content-Type header is malformed. Since it contains the '?' character, it needs to be quoted (look at the MIME RFC, section 5.1, definition of token).

现在，要反序列化它，您需要打开文档使用MTOM阅读器-和 XmlDictionaryReader.CreateMtomReader 可以为您提供确切的信息。创建该读取器后，您可以将其传递给 DataContractSerializer 来反序列化对象。下面的代码显示了如何完成此操作。

Now, to deserialize it, you need to open the document with a MTOM reader - and XmlDictionaryReader.CreateMtomReader will give you exactly that. With that reader created, you can pass it to the DataContractSerializer to deserialize the object. The code below shows how this can be done.

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

            [DataMember(Order = 2)]
            public Responses Responses { get; set; }
